There are some threads on the parent breed of the ameracauna breed. Quechua are a land race from South America. The parent breed for the auracauna is the Colloncas, another land race from South America. Land race breeds are not standardized and so are hard to quantify. Basicly, Quechua chickens come in just about every color and can lay many different color eggs, but they are tailed and have a 'winter face'. Colloncas can lay a rainbow of colors among even siblings and are known for gentleness, even among roosters. They are 'rumpless', meaning they have no tails, not even tail bones. Colloncas are clean faced and have no tufts or earrings.
