Ameraucana
The Ameraucana is an American breed of domestic chicken. It was developed in the United States in the 1970s, and derives from Araucana chickens brought from Chile. It was bred to retain the blue-egg gene but eliminate the lethal alleles of the parent breed. There are both standard-sized and bantam versions. History The Ameraucana was developed in the United States in the 1970s from Araucana chickens brought from Chile. It was bred to retain the unusual blue-egg gene of the Araucana, but eliminate the tufted and rumpless lethal alleles of the parent breed. It was added to the Standard of Perfection of the American Poultry Association in 1984. The name derives from "America" and "Araucana". The Ameraucana is recognized in the United States as a separate breed from the Araucana. In some other countries, including Australia and the United Kingdom, both the tailed and rumpless variants of the Araucana are considered a single breed.

Araucana
The Araucana ( es, Gallina Mapuche, italic=no) is a breed of domestic chicken from Chile. Its name derives from the AraucanÃa region of Chile where it is believed to have originated. It lays blue-shelled eggs, one of very few breeds that do so. Breed standards for the Araucana vary from country to country. It may have unusual tufts of feathers on the ears, and may be rumpless, without a tail and tail-bone; in the United States it may for this reason be known as the South American Rumpless. Both ear-tufts and rumplessness are caused by lethal genes, so not all birds display these traits. The Ameraucana breed and "Easter egger" hybrids of the United States, which also lay blue or green eggs, both derive from the Araucana. History The early history of the Araucana is not documented. The birds were commonly seen in South America in the early twentieth century. The Spanish aviculturist Salvador Castelló, who visited Chile in 1914, saw them and named them "Gallina Araucana", as m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicken
The chicken (''Gallus gallus domesticus'') is a domesticated junglefowl species, with attributes of wild species such as the grey and the Ceylon junglefowl that are originally from Southeastern Asia. Rooster or cock is a term for an adult male bird, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen and a sexually immature female is called a pullet. Humans now keep chickens primarily as a source of food (consuming both their meat and eggs) and as pets. Traditionally they were also bred for cockfighting, which is still practiced in some places. Chickens are one of the most common and widespread domestic animals, with a total population of 23.7 billion , up from more than 19 billion in 2011. There are more chickens in the world than any other bird. There are numerous cultural references to chickens – in myth, folklore and religion, and in language and literature.

Breed
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. 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. Another point of view is that a breed is consistent enough in type to be logically grouped together and when mated within the group produce the same type. When bred together, ind ...

Lethal Allele
Lethal alleles (also referred to as lethal genes or lethals) are alleles that cause the death of the organism that carries them. They are usually a result of mutations in genes that are essential for growth or development. Lethal alleles may be recessive, dominant, or conditional depending on the gene or genes involved. Lethal alleles can be embryonically lethal, in which the fetus will never survive to term, or may be lethal perinatally or postnatally after an extended period of apparently normal development. Embryonically lethal alleles are a cause of non-Mendelian patterns of inheritance, such as the observation of traits in a 2:1 ratio. History Lethal alleles were first discovered by Lucien Cuénot in 1905 while studying the inheritance of coat colour in mice. The ''agouti'' gene in mice is largely responsible for determining coat colour. The wild-type allele produces a blend of yellow and black pigmentation in each hair of the mouse. This yellow and black blend may be ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bantam (chicken)
A bantam is any small variety of fowl, usually of chicken or duck. Most large chicken breeds and several breeds of duck have a bantam counterpart, which is much smaller than the standard-sized fowl, but otherwise similar in most or all respects. A true bantam chicken is naturally small and has no large counterpart. Etymology The word ''bantam'' derives from the name of the seaport city of Bantam in western Java, Indonesia. European sailors restocking on live fowl for sea journeys found the small native breeds of chicken in Southeast Asia to be useful, and any such small poultry came to be known as a ''bantam''.

American Standard Of Perfection
The ''American Standard of Perfection'' is the official breed standard for the poultry fancy in North America. First published in 1874 by the American Poultry Association, the ''Standard of Perfection'' (commonly referred to as "the ''Standard''") classifies and describes the standard physical appearance, coloring and temperament for all recognized breeds of poultry, including chickens, ducks, turkeys, and geese. The current edition was published in 2015. Use The ''Standard'' is used by American Poultry Association judges at sanctioned poultry shows to judge poultry, and by those who participate in the competitive showing of selectively bred birds that conform to the standard, which led to the term "standard bred" poultry. History The first edition of the book listed 41 breeds, and today's versions have nearly 60. There are 19 classes of poultry recognized by the American Poultry Association. Eleven of these classes are devoted to chickens, of which six are classes of large bree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Poultry Association
The American Poultry Association (APA) is the oldest poultry organization in the North America. It was founded in 1873, and incorporated in Indiana in 1932. The first American poultry show was held in 1849, and the APA was later formed in response to the burgeoning need for an overseeing body to set standards for poultry breeds and to administer judging. A year after its foundation, the Association published the first ''American Standard of Perfection'', which to this day is the most widely used and respected handbook on poultry breed standards. The APA continues to publish and expand the ''Standard'', and aims to promote all aspects of poultry fancy by certifying official judges, sponsoring shows, fostering youth participation, and advocating for its members, in both the U.S. and Canada. The Poultry Standard of Perfection Once the APA was formed in 1849, they made it their first order of business to create a standard for American poultry breeds. Six members from the original m ...

Comb (anatomy)
A comb is a fleshy growth or crest on the top of the head of some gallinaceous birds, such as domestic chickens. The alternative name cockscomb (with several spelling variations) reflects the fact that combs are generally larger on cock birds than on hens. The comb is one of several fleshy protuberances on the heads of chickens, the others being the wattles and earlobes, which collectively are called caruncles. In turkeys, the caruncles are the fleshy nodules on the head and throat. Chicken combs are most commonly red, but may also be black or dark purple in breeds such as the Silkie or the Sebright. In other species the color may vary from light grey to deep blue or red. The comb may be a reliable indicator of health or vigor and is used for mate-assessment in some poultry species. Types of chicken comb Comb shape varies considerably depending on the breed or species of bird. Of the many types and shapes seen in chicken cocks the principal ones are: * the single comb, ...

Wattle (anatomy)
A wattle is a fleshy caruncle hanging from various parts of the head or neck in several groups of birds and mammals. Caruncles in birds include those found on the face, wattles, dewlaps, snoods, and earlobes. Wattles are generally paired structures, but may occur as a single structure when it is sometimes known as a dewlap. Wattles are frequently organs of sexual dimorphism. In some birds, caruncles are erectile tissue and may or may not have a feather covering. Wattles are often such a striking morphological characteristic of animals that it features in their common name. For example, the southern and northern cassowaries are known as the double-wattled and single-wattled cassowary, respectively, and a breed of domestic pig is known as the Red Wattle. Birds Function In birds, wattles are often an ornament for courting potential mates. Large wattles are correlated with high testosterone levels, good nutrition, and the ability to evade predators, which in turn indicates a ...
