There is also a blue egg chicken in China, the Dongxiang, with black skin, muscle, and bone. The Araucana Club's latest newsletter has an article and pictures of it. They have probably been around since they came off Noah's ark, but most people don't prefer black meat, hence their lack of popularity, at least in this country.
