Poultry are domesticated birds kept by humans for their eggs, their meat or their feathers. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes.
The chicken is a type of domesticated fowl, a subspecies of the red junglefowl. Chickens are one of the most common and widespread domestic animals, with a total population of 23.7 billion as of 2018, up from more than 19 billion in 2011. There are more chickens in the world than any other bird or domesticated fowl. Humans keep chickens primarily as a source of food and, less commonly, as pets. Originally raised for cockfighting or for special ceremonies, chickens were not kept for food until the Hellenistic period.
Domestication is a sustained multi-generational relationship in which one group of organisms assumes a significant degree of influence over the reproduction and care of another group to secure a more predictable supply of resources from that second group.
Animal husbandry is the branch of agriculture concerned with animals that are raised for meat, fibre, milk, eggs, or other products. It includes day-to-day care, selective breeding and the raising of livestock.
A breed is a specific group of domestic animals having homogeneous appearance (phenotype), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species. In literature, there exist several slightly deviating definitions. Breeds are formed through genetic isolation and either natural adaptation to the environment or selective breeding, or a combination of the two. Despite the centrality of the idea of "breeds" to animal husbandry and agriculture, no single, scientifically accepted definition of the term exists. It was shown by set-theoretic means that for the term breed an infinite number of different definitions, which more or less meet the common requirements found in literature, can be given. A breed is therefore not an objective or biologically verifiable classification but is instead a term of art amongst groups of breeders who share a consensus around what qualities make some members of a given species members of a nameable subset.
The Araucana is a breed of domestic chicken from Chile. Its name derives from the Araucanía region of Chile where it is believed to have originated. It lays blue-shelled eggs, one of very few breeds that do so.
A landrace is a domesticated, locally adapted, traditional variety of a species of animal or plant that has developed over time, through adaptation to its natural and cultural environment of agriculture and pastoralism, and due to isolation from other populations of the species. Landraces are generally distinguished from cultivars, and from breeds in the standardized sense, although the term landrace breed is sometimes used as distinguished from the term standardized breed when referring to cattle.
The domestication of animals is the mutual relationship between animals and the humans who have influence on their care and reproduction. Charles Darwin recognized a small number of traits that made domesticated species different from their wild ancestors. He was also the first to recognize the difference between conscious selective breeding in which humans directly select for desirable traits, and unconscious selection where traits evolve as a by-product of natural selection or from selection on other traits. There is a genetic difference between domestic and wild populations. There is also a genetic difference between the domestication traits that researchers believe to have been essential at the early stages of domestication, and the improvement traits that have appeared since the split between wild and domestic populations. Domestication traits are generally fixed within all domesticates, and were selected during the initial episode of domestication of that animal or plant, whereas improvement traits are present only in a proportion of domesticates, though they may be fixed in individual breeds or regional populations.
The Yurlov Crower is an old Russian breed of chicken primarily selected and used for long crowing cock contests in Russia.
Gamebird hybrids are the result of crossing species of game birds, including ducks, with each other and with domestic poultry. These hybrid species may sometimes occur naturally in the wild or more commonly through the deliberate or inadvertent intervention of humans.
The poulet de Bresse or volaille de Bresse is a French chicken product which has appellation d'origine contrôlée status. It may be produced only from white chickens of the Bresse breed raised within a legally-defined area of the historic region and former province of Bresse, in eastern France.
The Sebright is a British breed of bantam chicken. It is a true bantam – a miniature bird with no corresponding large version – and is one of the oldest recorded British bantam breeds. It is named after Sir John Saunders Sebright, who created it as an ornamental breed by selective breeding in the early nineteenth century.
Solid black plumage color refers to a plumage pattern in chickens characterized by a uniform, black color across all feathers. There are chicken breeds where the typical plumage color is black, such as Australorp, Sumatra, White-Faced Black Spanish, Jersey Giant and others. And there are many other breeds having different color varieties, which also have an extended black variety, such as Leghorn, Minorca, Wyandotte, Orpington, Langshan and others.
Koen Vanmechelen is an internationally acclaimed Belgian multi- and transdisciplinary artist who began his career in the early 1990s. He is one of the most prolific and prominent contemporary artists in Belgium. His ground-breaking work deals with biocultural diversity and identity. Central to his oeuvre is the chicken, which, through his projects, is revealed as both an artwork and a metaphor for society. By bringing together and exploring the interplay between art, science and philosophy in his work, Vanmechelen reflects upon our global heritage and examines the way that we choose to live and evolve. Multi-disciplinary scientific collaborations and community engagement are integral to Vanmechelen's approach.
The Bresse Gauloise is a French breed of domestic chicken. It originates in the historic region and former province of Bresse, in the regions of Rhône-Alpes, Bourgogne and Franche-Comté, in eastern France. Because of legal restrictions on the use of the name, only white chickens raised within that area may be called "Bresse"; outside it, they are given the name "Gauloise"; the breed name combines both. Four colours are recognised for the Bresse Gauloise, three of them linked to areas within Bresse: the Bresse de Bourg is "grey" (silver-pencilled); the Bresse de Bény is white; the Bresse de Louhans is black; a blue variety has recently been created. White Bresse de Bény chickens and capons raised in the area of Bresse have appellation d'origine contrôlée status and are marketed as poulet de Bresse; they are regarded as a premium product and command higher prices than other chickens.
The Alsacienne or French: Poule d'Alsace is a breed of domestic chicken from Alsace, in eastern France. It was selectively bred in the 1890s, at a time when Alsace was part of the German Empire. Unlike most other French breeds, it has not been cross-bred with imported Oriental stock.
Animal genetic resources for food and agriculture (AnGR) are a subset of genetic resources and a specific element of agricultural biodiversity. The term animal genetic resources refers specifically to the genetic resources of avian and mammalian species, which are used for food and agriculture purposes. Further terms referring to AnGR are "farm animal genetic resources" or "livestock diversity".
The Malines, Dutch: 'Mechelse Koekoek', is a Belgian breed of large domestic chicken. It originates from the area of Mechelen, in the province of Antwerp in Flanders, for which it is named. It was created in the nineteenth century by cross-breeding local cuckoo-patterned farm chickens with various different types of imported Oriental chicken. With the Jersey Giant, it is among the heaviest of all chicken breeds. It is valued for the quality of its meat, which is pale in colour and fine-textured.
The Satsumadori is a Japanese breed of chicken. It originated in Kagoshima Prefecture, in the southernmost part of the island of Kyushu in southern Japan, and was originally bred for cockfighting. The name derives from that of the former province of Satsuma, now the western part of Kagoshima Prefecture.
