  • The breed is recognized by the American Poultry Association and also comes in a bantam size and a variety of colors: White, Black, Black Breasted Red, Golden Duckwing and Silver Duckwing. 
  • It is known for its unique blue-green eggs, which are a result of the breed’s genetics. But this original layer of blue eggs gave way to other blue-egg-laying breeds such as Ameraucanas and Easter Eggers in recent years.
  • The breed is native to Chile and was first discovered by Spanish conquistadors in the 16th century. 
  • This unusual breed is rumpless (aka having no tail) and also lacks a tailbone and oil (or preen) gland. 
  • One of the most striking features of this breed is its ear tufts, which are a feather or group of feathers coming out of the sides of the bird’s face around the ear area. They can be one-sided or bilateral (which is preferred).
