The Ameraucana is an American breed of domestic chicken developed in the United States in the 1970s. It was derived from chickens brought from South American that carried the blue egg gene, and was bred to maintain the blue egg color of that breed while eliminating the lethal recessive gene. There is also an Ameraucana bantam variety. The Ameraucana was bred from chickens from Chile. A breeder's club, now called the Ameraucana Breeders Club, was formed in 1976. Both the full-sized bird and the bantam were added to the Standard of Perfection of the American Poultry Association in 1984.
The Ameracucana is one of the few chicken breeds to lay blue eggs; another is the Cream Legbar, which also has Araucana influence. The Ameraucana shows many similarities to the Araucana, including the pea comb and the blue egg gene. The Araucana has earmuffs and is rumpless; the Ameraucana has a tail and is muffed and bearded. 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 variety. In Australia and the UK both breeds are viewed as varieties of the Araucana - tailed and rumpless.
The Ameraucana lays about 250 blue eggs of various shades per year. It has an unusually long laying season. Birds start laying at about 5 or 6 months old. Ameraucanca traits are dominant and when crossed with other breeds the offspring will resemble the Ameraucana. Easter Eggers have been sold as purebred Ameraucanas.
