The Araucana, also known in the USA as a South American Rumpless,[1] is a breed of chicken originating in Chile. The Araucana is often confused with other fowl, especially the Ameraucana and Easter Egger chickens, but has several unusual characteristics which distinguish it. They lay blue eggs, have feather tufts near their ears, and a tail. To comply with the north American standard they must have no tail and are rumpless.

History
The ancestors of the modern Araucana chicken were purportedly first bred by the Araucanians Indians of Chile -- hence the name "Araucana." The Araucana as we know it today is a hybrid of two South American breeds: the Collonca (a naturally blue-egg laying, rumpless, clean-faced chicken) and the Quetro (a pinkish-brown egg layer that is tailed and has ear-tufts). The Collonca male and female are very similar, with very few secondary sexual characteristics like comb, wattles or tail coverts to distinguish them. Naturally, after centuries of introgression with other South American races, for example, Quechua, Huapi, Ona and Mapuche, South American Indian villages Colloncas are more often than not, composites. The Quetro or Quetero is also nearly combless but the sexes are markedly dichromatic. The male of both Colloncas and Quetero have unusual voices. The Quetero has a multi-syllabilic laughing crow. Colloncas have a slightly musical crow. Muffs and beards are present in most South American domestic fowl. The European equivalent of the North American show standard variety Araucana is what one comes across in South American villages. Quechua and Mapuche do not have tufts and resemble the Ameraucana. The Quechua is larger, and more powerfully built. It is shaped more like a game fowl than the Mapuche which is smaller, lighter and less domesticated in the sense that it is a semi-feral bird while the Quechua is a domestic bird reared for meat and eggs. The Mapuche is also known as the Chilean Passion Fowl and the Aymara Fire Fowl. Mapuche are generally crested and exhibit markedly colorful plumage in both sexes. The Quechua is unremarkable in plumage, closely resembling the North American standard Ameraucana. a composite between many of the South American domestic fowl races is known as the Falklands Isles Hen. These birds are descended from many different strains of birds purchased from Indian villages on the eastern coast of South America. The Falkland Isles hen is the progenitor of the Shetland Isles hen, U.K. Araucana and Ameraucana.
The current world wide Araucana Standard (except North America) indicates a medium to large sized chicken with a tail that lays bluish-green eggs. Specific features are feather ear tufts, muffs and beards, with a very much reduced comb, a small feather crest and a complete absence of wattles. The current North American standard calls for a chicken that is rumpless (missing their last vertebrae and lacking a tail), possesses ear-tufts (feathers that grow out from near the birds' ears), and lays blue eggs. In the United States and Canada, muffs, beards, and tails are all disqualifications.
Araucanas are often confused with two other types of colored-egg-laying chickens: Ameraucanas and Easter Eggers.
The Ameraucana should also lay blue eggs, but unlike the Araucana it has a tail and possesses muffs and a beard, which are quite different from the tufts of the Araucana, and no feather crest. Muffs and beards provide insulation against the cold. They are downy filoplumes that grow on the face below the eyes, extending to beyond the ears as well as the throat. Earrings or "Tufts" as they are known in Western countries are actual feathers that grow from fleshy lobes called peduncles on either side of the birds' face. Quetero are prominently tufted but many females have only small earrings or lack them altogether. Tufts are associated with a lethal gene, which makes them difficult to attain.
The Easter Egg Chicken is not an actual breed; the term refers to any bird that lays colored eggs. The vast majority of birds sold as "Araucanas" or "Ameraucanas" are actually neither. Instead, they are mixed breeds with no APA (American Poultry Association) Standard that lay colored eggs, ranging from bluish and greenish to pinkish-brown, and sometimes even tan, gray or white.
The Araucana's eggs are not more nutritious than eggs of other colors (despite popular myth), but the birds are reliable layers of medium-sized eggs. Because of the Araucanas' capacity to forage for much their own food, the egg yolks tend to be more nutritious than those of large standard breeds that prove to be less efficient forages. The Araucana, if hand-raised specifically, is extremely well-tempered, calm and trusting.
