Araucanas originated in Chile. It is speculated that this breed was developed prior to Old World contact, which would make them the only breed of chicken native to the Americas. Araucanas are very rare in the United States. They are rumpless, meaning they have no tail feathers, and have ear tufts. They do not have beards or muffs like an Ameraucana. Their rarity is likely due to the fact that the gene for ear tufts is a lethal gene.
