81-461: Ducks with buff coloration are a cross between Indian Runner, Rouen and Aylesbury ducks. Their origin originates from the renowned Orpington farms in England, which is why they are also known as Orpington ducks. The buff-coloured plumage of the breed was developed by a man named William Cook from the same region. During this period, buff was a very fashionable colour. As well as the black, the chocolate, and

162-634: A capon , has more tender and flavorful meat, as well. A bantam is a small variety of domestic chicken, either a miniature version of a member of a standard breed , or a "true bantam" with no larger counterpart. The name derives from the town of Bantam in Java where European sailors bought the local small chickens for their shipboard supplies. Bantams may be a quarter to a third of the size of standard birds and lay similarly small eggs. They are kept by small-holders and hobbyists for egg production, use as broody hens, ornamental purposes, and showing. Cockfighting

243-544: A 94% share of the 2.6 million tonne global market. Global egg production was expected to reach 65.5 million tonnes in 2013, surpassing all previous years. Between 2000 and 2010, egg production was growing globally at around 2% per year, but since then growth has slowed down to nearer 1%. In 2018, egg production reached 76.7 million tonnes, a huge 24% growth since 2008. Poultry is available fresh or frozen, as whole birds or as joints (cuts), bone-in or deboned, seasoned in various ways, raw or ready cooked. The meatiest parts of

Poultry Poultry ( / ˈ p oʊ l t r i / ) are domesticated birds kept by humans for the purpose of harvesting animal products such as meat , eggs or feathers . The practice of raising poultry

405-458: A bird are the flight muscles on its chest, called "breast" meat, and the walking muscles on the legs , called the "thigh" and "drumstick". The wings are also eaten ( Buffalo wings are a popular example in the United States) and may be split into three segments, the meatier "drumette", the "wingette" (also called the "flat"), and the wing tip (also called the "flapper"). In Japan, the wing

486-461: A broody hen, because when raised in this way, the ducks "lay aside their wild nature and without hesitation breed when shut up in the bird pen". Despite this, ducks did not appear in agricultural texts in Western Europe until about 810 AD, when they began to be mentioned alongside geese, chickens, and peafowl as being used for rental payments made by tenants to landowners. It is widely agreed that

567-526: A disease of birds caused by bird-specific influenza A virus that is not normally transferred to people; however, people in contact with live poultry are at the greatest risk of becoming infected with the virus and this is of particular concern in areas such as Southeast Asia, where the disease is endemic in the wild bird population and domestic poultry can become infected. The virus possibly could mutate to become highly virulent and infectious in humans and cause an influenza pandemic . Bacteria can be grown in

648-401: A fenced yard and poultry house at a higher stocking rate. Poultry can also be kept in a barn system, with no access to the open air, but with the ability to move around freely inside the building. The most intensive system for egg-laying chickens is battery cages , often set in multiple tiers. In these, several birds share a small cage which restricts their ability to move around and behave in

729-606: A larger scale, and modern high-output poultry farms were present in the United Kingdom from around 1920 and became established in the United States soon after the Second World War . By the mid-20th century, the poultry meat-producing industry was of greater importance than the egg-laying industry. Poultry breeding has produced breeds and strains to fulfil different needs; light-framed, egg-laying birds that can produce 300 eggs

810-416: A long, straddling gait. They roost in trees and forage on the ground, feeding on seeds, nuts, berries, grass, foliage, invertebrates, lizards, and small snakes. The modern domesticated turkey is descended from one of six subspecies of wild turkey ( Meleagris gallopavo ) found in the present Mexican states of Jalisco , Guerrero and Veracruz . Pre-Aztec tribes in south-central Mexico first domesticated

891-463: A means to save them from going extinct. More specifically, in 2020 the Science Advances published a study where they concluded that the work and population of human beings has affected the growth of animals going extinct around the world. The uproar of animals going extinct has caused zoos to use their captive breeding programs on endangered animals in an effort to create a stronger population. It

972-754: A normal manner. The eggs are laid on the floor of the cage and roll into troughs outside for ease of collection. Battery cages for hens have been illegal in the EU since January 1, 2012. Chickens raised intensively for their meat are known as "broilers". Breeds have been developed that can grow to an acceptable carcass size (2 kg or 4 lb 7 oz) in six weeks or less. Broilers grow so fast, their legs cannot always support their weight and their hearts and respiratory systems may not be able to supply enough oxygen to their developing muscles. Mortality rates at 1% are much higher than for less-intensively reared laying birds which take 18 weeks to reach similar weights. Processing

1053-702: A preventative measure. Diseases can also be common and spread rapidly through the flock. In extensive systems, the birds are exposed to adverse weather conditions and are vulnerable to predators and disease-carrying wild birds. Barn systems have been found to have the worst bird welfare. In Southeast Asia , a lack of disease control in free-range farming has been associated with outbreaks of avian influenza . In many countries, national and regional poultry shows are held where enthusiasts exhibit their birds which are judged on certain phenotypical breed traits as specified by their respective breed standards . The idea of poultry exhibition may have originated after cockfighting

1134-421: A process known as environmental enrichment . The goals of environmental enrichment are to make environments more complex and fluid, offer more engaging and complex processes, and give animals more chances to make decisions. Techniques that are commonly used to provide environmental enrichment include social, occupation, physical, sensory, and nutritional. Another type of abnormal behavior shown in captive animals

1215-469: A recessive sex-linked dilution factor. It was found that a deficiency of vitamin U resulted in widespread deposition of black pigment in the feathers of buff orpington ducks, a breed normally not known for black pigmentation. The Buff Orpington duck eats insects, larvae, aquatic invertebrates, seeds, acorns, aquatic vegetation, and grains; they require regular freshwater access. In general, the Buff offers much to

1296-453: A study has shown that zoo visitors density positively correlates with the number of gorillas banging on the barrier, and that low zoo visitors density caused gorillas to behave in a more relaxed way. Captive animals often cannot escape the attention and disruption caused by the general public, and the stress resulting from this lack of environmental control may lead to an increased rate of self-injurious behaviors. There are studies that suggest

1377-412: A variety of animal and plant materials such as aquatic insects, molluscs, worms, small amphibians, waterweeds, and grasses. They feed in shallow water by dabbling, with their heads underwater and their tails upended. Most domestic ducks are too heavy to fly, and they are social birds, preferring to live and move around together in groups. They keep their plumage waterproof by preening, a process that spreads

1458-482: A vegetable garden clear of pests and will eat the ticks that carry Lyme disease . They happily roost in trees and give a loud vocal warning of the approach of predators. Their flesh and eggs can be eaten in the same way as chickens, young birds being ready for the table at the age of about four months. A squab is the name given to the young of domestic pigeons that are destined for the table. Like other domesticated pigeons, birds used for this purpose are descended from

1539-420: A year; fast-growing, fleshy birds destined for consumption at a young age, and utility birds which produce both an acceptable number of eggs and a well-fleshed carcase. Male birds are unwanted in the egg-laying industry and can often be identified as soon as they are hatch for subsequent culling. In meat breeds, these birds are sometimes castrated (often chemically) to prevent aggression. The resulting bird, called

1620-491: Is stereotypical behaviors , i.e. repetitive and apparently purposeless motor behaviors. Examples of stereotypical behaviours include pacing, self-injury, route tracing and excessive self-grooming. These behaviors are associated with stress and lack of stimulation. Animals that exhibit this tend to suffer from zoochosis , as it is manifested in stereotypical behaviors. Many who keep animals in captivity attempt to prevent or decrease stereotypical behavior by introducing stimuli,

1701-502: Is a jerking motion applied to one's own hair with hands or teeth, thus resulting in its excessive removal. The proximal causes of self-injurious behavior have been widely studied in captive primates ; either social or nonsocial factors can trigger this type of behavior. Social factors include changes in group composition, stress, separation from the group, approaches by or aggression from members of other groups, conspecific male individuals nearby, separation from females, and removal from

1782-496: Is accompanied by low levels of fat which have a favourable mix of fatty acids. Chicken meat contains about two to three times as much polyunsaturated fat as most types of red meat when measured by weight. However, for boneless, skinless chicken breast, the amount is much lower. 100 grams (3.5 oz) of raw chicken breast contains 2 grams (0.071 oz) of fat and 22 grams (0.78 oz) of protein, compared to 9 grams (0.32 oz) of fat and 20 grams (0.71 oz) of protein for

1863-406: Is frequently separated, and these parts are referred to as 手羽元 ( teba-moto "wing base") and 手羽先 ( teba-saki "wing tip"). Dark meat, which avian myologists refer to as "red muscle", is used for sustained activity—chiefly walking, in the case of a chicken. The dark color comes from the protein myoglobin , which plays a key role in oxygen uptake and storage within cells. White muscle, in contrast,

1944-399: Is known as poultry farming . These birds are most typically members of the superorder Galloanserae ( fowl ), especially the order Galliformes (which includes chickens , quails , and turkeys ). The term also includes waterfowls of the family Anatidae ( ducks and geese ) but does not include wild birds hunted for food known as game or quarry . Recent genomic studies involving

2025-417: Is large and broad, with an oval head and medium-length bill, as well as a gracefully curved neck. The Buff duck's body carries itself 20 degrees above horizontal, and its wings are short and curved. It has buff plumage and has a yellowish snout and feet, as well as brown eyes. Duck's bills are brown-orange, whereas the drakes' bills are yellow. In the U.S., there existed a blue variety of Orpington duck, but it

2106-504: Is predominantly in southwestern China, northern Thailand and Myanmar. These domesticated chickens spread across Southeast and South Asia where they interbred with local wild species of junglefowl, forming genetically and geographically distinct groups. Analysis of the most popular commercial breed shows that the White Leghorn breed possesses a mosaic of divergent ancestries inherited from subspecies of red junglefowl. Chickens were one of

2187-478: Is said that zoos are responsible for reducing the number of animals on the endangered species list and from extinction. Zoos could also be known as a place where animals are put into after they are taken out of their natural habitat . When animals are pulled out from their native habitat and taken to a location they are unfamiliar with, then it is said that animals may experience shock and poor mental health. Furthermore, some wild animals have died inside zoos due to

2268-523: Is said to be the world's oldest spectator sport. Two mature males (cocks or roosters) are set to fight each other, and will do so with great vigour until one is critically injured or killed. Cockfighting is extremely widespread in Island Southeast Asia , and often had ritual significance in addition to being a gambling sport. They also formed part of the cultures of ancient India, China, Persia, Greece, Rome, and large sums were won or lost depending on

2349-416: Is self-injurious behavior (SIB). Self-injurious behavior indicates any activity that involves biting, scratching, hitting, hair plucking, or eye poke that may result in injuring oneself. Although its reported incidence is low, self-injurious behavior is observed across a range of primate species, especially when they experience social isolation in infancy. Self-bite involves biting one's own body—typically

2430-766: Is suitable only for short bursts of activity such as, for chickens, flying. Thus, the chicken's leg and thigh meat are dark, while its breast meat (which makes up the primary flight muscles) is white. Other birds with breast muscle more suitable for sustained flight, such as ducks and geese, have red muscle (and therefore dark meat) throughout. Some cuts of meat including poultry expose the microscopic regular structure of intracellular muscle fibrils which can diffract light and produce iridescent colors, an optical phenomenon sometimes called structural coloration . As of 2022, no clinical trials have assessed poultry intake on human health. Poultry meat and eggs provide nutritionally beneficial food containing protein of high quality. This

2511-576: Is that people with egg allergies are unable to be immunised, but this disadvantage may be overcome as new techniques for cell-based rather than egg-based culture become available. Cell-based culture will also be useful in a pandemic when it may be difficult to acquire a sufficiently large quantity of suitable sterile, fertile eggs. Captivity (animal) Animal captivity is the confinement of domestic and wild animals. More specifically, animals that are held by humans and prevented from escaping are said to be in captivity . The term animal captivity

2592-433: Is the second most widely eaten type of meat in the world, accounting for about 30% of total meat production worldwide compared to pork at 38%. Sixteen billion birds are raised annually for consumption, more than half of these in industrialised, factory-like production units. Global broiler meat production rose to 84.6 million tonnes in 2013. The largest producers were the United States (20%), China (16.6%), Brazil (15.1%) and

2673-551: Is usually applied to wild animals that are held in confinement, but this term may also be used generally to describe the keeping of domesticated animals such as livestock or pets . This may include, for example, animals in farms , private homes, zoos , and laboratories . Animal captivity may be categorized according to the particular motives, objectives, and conditions of the confinement. All throughout history, domestic animals like pets and livestock were kept in captivity and tended by humans. However, pets and livestock were not

"Poultry" is a term used for any kind of domesticated bird, captive-raised for its utility, and traditionally the word has been used to refer to wildfowl ( Galliformes ) and waterfowl ( Anseriformes ) but not to cagebirds such as songbirds and parrots . "Poultry" can be defined as domestic fowls, including chickens, turkeys, geese and ducks, raised for

2835-605: The domesticated animals carried with the sea-borne Austronesian migrations into Taiwan , Island Southeast Asia , Island Melanesia , Madagascar , and the Pacific Islands ; starting from around 3500 to 2500 BC. By 2000 BC, chickens seem to have reached the Indus Valley and 250 years later, they arrived in Egypt. They were still used for fighting and were regarded as symbols of fertility. The Romans used them in divination , and

2916-427: The leaf litter for seeds, invertebrates, and other small animals. They seldom fly except as a result of perceived danger, preferring to run into the undergrowth if approached. Today's domestic chicken ( Gallus gallus domesticus ) is mainly descended from the wild red junglefowl of Asia, with some additional input from grey junglefowl , Sri Lankan junglefowl , and green junglefowl . Genomic studies estimate that

2997-478: The mallard ( Anas platyrhynchos ) is the ancestor of all breeds of domestic duck (with the exception of the Muscovy duck ( Cairina moschata ), which is not closely related to other ducks). Ducks are farmed mainly for their meat, eggs, and down . As is the case with chickens, various breeds have been developed, selected for egg-laying ability, fast growth, and a well-covered carcase. The most common commercial breed in

3078-437: The rock dove ( Columba livia ). Special utility breeds with desirable characteristics are used. Two eggs are laid and incubated for about 17 days. When they hatch, the squabs are fed by both parents on "pigeon's milk", a thick secretion high in protein produced by the crop . Squabs grow rapidly, but are slow to fledge and are ready to leave the nest at 26 to 30 days weighing about 500 g (1 lb 2 oz). By this time,

3159-529: The swan goose ( Anser cygnoides ), domesticated in Siberia about a thousand years later, is known as a Chinese goose . The two hybridise with each other and the large knob at the base of the beak, a noticeable feature of the Chinese goose, is present to a varying extent in these hybrids. The hybrids are fertile and have resulted in several of the modern breeds. Despite their early domestication, geese have never gained

With their assistance, zoos and aquariums are able to have the proper necessities needed in recovery programs to prevent animals from going extinct. Annually, it is subjected that thousands of wild animals end up in captivity due to the wild animal trade. These animals can be held in captivity because of

3321-484: The AZA, ( Association of Zoos and Aquariums ), may hold animals’ captive as a means to save them from extinction . For example, the AZA SAFE, (Save Animals From Extinction), promotes well-being and care of animals, conservation, and additional disciplines in order to protect and aid the wildlife. The organization focuses on creating recovery plans , cooperation between AZA workers, and advancement of conservation. Furthermore,

3402-545: The Egyptians made a breakthrough when they learned the difficult technique of artificial incubation . Since then, the keeping of chickens has spread around the world for the production of food with the domestic fowl being a valuable source of both eggs and meat. Since their domestication, a large number of breeds of chickens have been established, but with the exception of the white Leghorn , most commercial birds are of hybrid origin. In about 1800, chickens began to be kept on

3483-486: The European Union (11.3%). There are two distinct models of production; the European Union supply chain model seeks to supply products which can be traced back to the farm of origin. This model faces the increasing costs of implementing additional food safety requirements, welfare issues and environmental regulations. In contrast, the United States model turns the product into a commodity. World production of duck meat

3564-557: The United Kingdom and the United States is the Pekin duck , which can lay 200 eggs a year and can reach a weight of 3.5 kg (7 lb 11 oz) in 44 days. In the Western world , ducks are not as popular as chickens, because the latter produce larger quantities of white, lean meat and are easier to keep intensively, making the price of chicken meat lower than that of duck meat. While popular in haute cuisine , duck appears less frequently in

3645-425: The adult pigeons will have laid and be incubating another pair of eggs and a prolific pair should produce two squabs every four weeks during a breeding season lasting several months. Worldwide, more chickens are kept than any other type of poultry, with over 50 billion birds being raised each year as a source of meat and eggs. Traditionally, such birds would have been kept extensively in small flocks, foraging during

3726-411: The arms, legs, shoulders, or genitals. Threat bite involves biting one's own body—typically the hand, wrist, or forearm—while staring at the observer, conspecific, or mirror in a threatening manner. Self-hit involves striking oneself on any part of the body. Eye poking is a behavior (widely observed in primates ) that presses the knuckle or finger into the orbital space above the eye socket. Hair plucking

3807-614: The attractions of rearing geese is their ability to grow and thrive on a grass-based system. They are very gregarious and have good memories and can be allowed to roam widely in the knowledge that they will return home by dusk. The Chinese goose is more aggressive and noisy than other geese and can be used as a guard animal to warn of intruders. The flesh of meat geese is dark-coloured and high in protein, but they deposit fat subcutaneously, although this fat contains mostly monounsaturated fatty acids . The birds are killed either around 10 or about 24 weeks. Between these ages, problems with dressing

3888-683: The bird around 800 BC, and Pueblo Indians inhabiting the Colorado Plateau in the United States did likewise around 200 BC. They used the feathers for robes, blankets, and ceremonial purposes. More than 1,000 years later, they became an important food source. The first Europeans to encounter the bird misidentified it as a guineafowl, a bird known as a "turkey fowl" at that time because it had been introduced into Europe via Turkey. Commercial turkeys are usually reared indoors under controlled conditions. These are often large buildings, purpose-built to provide ventilation and low light intensities (this reduces

3969-479: The birds is done automatically with conveyor-belt efficiency. They are hung by their feet, stunned, killed, bled, scalded, plucked, have their heads and feet removed, eviscerated, washed, chilled, drained, weighed, and packed, all within the course of little over two hours. Both intensive and free-range farming have animal welfare concerns. In intensive systems, cannibalism , feather pecking and vent pecking can be common, with some farmers using beak trimming as

4050-512: The birds permanently in captivity . Domesticated chickens may have been used for cockfighting at first and quail kept for their songs, but people soon realised the advantages of having a captive-bred source of food. Selective breeding for fast growth, egg-laying ability, conformation, plumage and docility took place over the centuries, and modern breeds often look very different from their wild ancestors. Although some birds are still kept in small flocks in extensive systems, most birds available in

4131-422: The birds' activity and thereby increases the rate of weight gain). The lights can be switched on for 24 h/day, or a range of step-wise light regimens to encourage the birds to feed often and therefore grow rapidly. Females achieve slaughter weight at about 15 weeks of age and males at about 19. Mature commercial birds may be twice as heavy as their wild counterparts. Many different breeds have been developed, but

4212-725: The blue variations, W. Cook created bibs on the chest that resembled white hearts. The American Poultry Associations recognized them in 1914 after Cook introduced them to the United States at the Madison Square Garden Show in New York City in 1908.By 2011, there were 793 breeding buff ducks in North America, with 11 breeders engaged in breeding the species. As of today, there are five primary breeding flocks with 50 or more breeding birds. Buff Orpington Ducks are medium-sized ducks that range between 7 and 8 pounds in weight. The bird

4293-506: The breeder who is seeking an attractive, dual-purpose bird. It produces 150 to 220 eggs per year and gains weight fairly rapidly, enabling it to be sold within eight to ten weeks of birth. The Buff Orpington is listed on the Rare Breed Survival Trust Watch List. The orpingtons are classified as light ducks, but they are on the larger size scale. Their eggs are produced at an average rate of 150 per year, which makes them

4374-562: The carcase occur because of the presence of developing pin feathers . In some countries, geese and ducks are force-fed to produce livers with an exceptionally high fat content for the production of foie gras . Over 75% of world production of this product occurs in France, with lesser industries in Hungary and Bulgaria and a growing production in China. Foie gras is considered a luxury in many parts of

4455-572: The chicken was domesticated 8,000 years ago in Southeast Asia and spread to China and India 2000–3000 years later. Archaeological evidence supports domestic chickens in Southeast Asia well before 6000 BC, China by 6000 BC and India by 2000 BC. A landmark 2020 Nature study that fully sequenced 863 chickens across the world suggests that all domestic chickens originate from a single domestication event of red junglefowl whose present-day distribution

4536-510: The commercial importance of chickens and ducks. Domestic geese are much larger than their wild counterparts and tend to have thick necks, an upright posture, and large bodies with broad rear ends. The greylag-derived birds are large and fleshy and used for meat, while the Chinese geese have smaller frames and are mainly used for egg production. The fine down of both is valued for use in pillows and padded garments. They forage on grass and weeds, supplementing this with small invertebrates, and one of

4617-530: The day and housed at night. This is still the case in developing countries, where the women often make important contributions to family livelihoods through keeping poultry. However, rising world populations and urbanization have led to the bulk of production being in larger, more intensive specialist units. These are often situated close to where the feed is grown or near to where the meat is needed, and result in cheap, safe food being made available for urban communities. Profitability of production depends very much on

4698-518: The first zoos as personal collections to demonstrate their dominance and wealth. These private collections of animals were known as menageries . Contrary to domestication, the ferociousness and natural behaviour of the wild animals were preserved and exhibited. Today, zoos claim to have other reasons for keeping animals under human care: conservation , education and science . Captive animals, especially those not domesticated, sometimes can develop abnormal behaviours . One type of abnormal behaviour

4779-551: The flesh of these birds. Poultry can be distinguished from "game", defined as wild birds or mammals hunted for food or sport, a word also used to describe the meat of these when eaten. Chickens are medium-sized, chunky birds with an upright stance and characterised by fleshy red combs and wattles on their heads. Males, known as cocks, are usually larger, more boldly coloured, and have more exaggerated plumage than females (hens). Chickens are gregarious, omnivorous , ground-dwelling birds that in their natural surroundings search among

4860-421: The four extant junglefowl species reveals that the domestication of chicken, the most populous poultry species, occurred around 8,000 years ago in Southeast Asia . This was previously believed to have occurred around 5,400 years ago, also in Southeast Asia. The process may have originally occurred as a result of people hatching and rearing young birds from eggs collected from the wild, but later involved keeping

4941-479: The group. Social isolation , particularly disruptions of early mother-rearing experiences, is an important risk factor. Studies have suggested that, although mother-reared rhesus macaques still exhibit some self-injurious behaviors, nursery-reared rhesus macaques are much more likely to self-abuse than mother-reared ones. Nonsocial factors include the presence of a small cut, a wound or irritant, cold weather, human contact, and frequent zoo visitors. For example,

Millions of eggs are used each year to generate the annual flu vaccine requirements, a complex process that takes about six months after the decision is made as to what strains of virus to include in the new vaccine. A problem with using eggs for this purpose

5103-461: The majority of commercial birds are white, as this improves the appearance of the dressed carcass, the pin feathers being less visible. Turkeys were at one time mainly consumed on special occasions such as Christmas (10 million birds in the United Kingdom) or Thanksgiving (60 million birds in the United States). However, they are increasingly becoming part of the everyday diet in many parts of

5184-644: The many abnormal captive behaviors, including self-injurious behavior , can be successfully treated by pair housing. Pair housing provides a previously single-housed animal with a same-sex social partner. This method is especially effective with primates, which are widely known to be social animals . Social companionship provided by pair housing encourages social interaction, thus reducing abnormal and anxiety-related behavior in captive animals as well as increasing their locomotion . Wild animals may be placed in captivity for conservation, studies, exotic pet trade, and farming . Places of captivity that are connected with

5265-418: The market today are reared in intensive commercial enterprises. Together with pork , poultry is one of the two most widely-eaten types of meat globally, with over 70% of the meat supply in 2012 between them; poultry provides nutritionally beneficial food containing high-quality protein accompanied by a low proportion of fat. All poultry meat should be properly handled and sufficiently cooked in order to reduce

5346-451: The mass-market food industry. However, things are different in the East. Ducks are more popular there than chickens and are mostly still herded in the traditional way and selected for their ability to find sufficient food in harvested rice fields and other wet environments. The greylag goose ( Anser anser ) was domesticated by the Egyptians at least 3000 years ago, and a different wild species,

5427-420: The only animals to be put in captivity and receive human care because wild animals had this as well. Despite the fact that wild animals have been harbored by humans for thousands of years, this captivity has not always come close to present zoos. Some were failed domestication attempts. Furthermore, the wealthy, predominantly the aristocrats and kings, collected wild animals for various reasons. The affluent built

5508-651: The outcome of an encounter. Breeds such as the Aseel were developed in the Indian subcontinent for their aggressive behaviour. Cockfighting has been banned in many countries during the last century on the grounds of cruelty to animals. Ducks are medium-sized aquatic birds with broad bills, eyes on the side of the head, fairly long necks, short legs set far back on the body, and webbed feet. Males, known as drakes, are often larger than females (known as hens) and are differently coloured in some breeds. Domestic ducks are omnivores , eating

5589-601: The overabundance of their population in roadside zoos. Additional reasons as to why animals may end up in captivity is because animals are captured from their original habitat, come from animal breeders , or come from the black market . When wild animals are captured and held in captivity, then they may be sold in pet stores , auction sales , or the World Wide Web . Zoos are known as a place where visitors come in to see wild animals. This means zoos may keep animals in confinement. For example, zoos may keep animals captive as

5670-404: The price of feed, which has been rising. High feed costs could limit further development of poultry production. In free-range husbandry, the birds can roam freely outdoors for at least part of the day. Often, this is in large enclosures, but the birds have access to natural conditions and can exhibit their normal behaviours. A more intensive system is yarding , in which the birds have access to

5751-418: The production of meat or eggs and the word is also used for the flesh of these birds used as food. The Encyclopædia Britannica lists the same bird groups but also includes guinea fowl and squabs (young pigeons). In R. D. Crawford's Poultry breeding and genetics , squabs are omitted but Japanese quail and common pheasant are added to the list, the latter frequently being bred in captivity and released into

5832-399: The raw product is still present. Also, some risk is present for consumers of poultry meat and eggs to bacterial infections such as Salmonella and Campylobacter .
