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.

History

The Ameraucana was developed in the United States in the 1970s from Araucana chickens brought from Chile.^{[6]: 37 [7]: 11} 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.^[6]: 37 It was added to the Standard of Perfection of the American Poultry Association in 1984.^[2] The name derives from "America" and "Araucana".^[6]: 37

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.^[7]: 11

Characteristics

The Ameraucana is one of the few chicken breeds to lay blue eggs.^[7]: 11 It shows many similarities to the Araucana, including the pea comb and the blue egg gene. It is tailed, muffed and bearded, whereas the Araucana in the United States has ear tufts and is rumpless.^[8] The earlobes are small and round, the wattles small or absent; earlobes, comb and wattles are all red. The shanks are slate-blue, tending to black in the black plumage variant.^[6]: 37

Nine color variants are recognized in the American Standard of Perfection: black, blue, blue wheaten, brown red, buff, silver, wheaten, white, and blue.^[2]
