Can anyone give me more info on the genes that make Jaerhon chicks autosexing? I love this breed, but I can't seem to find much information at all. I adopted some hens (couldn't find a roo), and crossed them with my Black Ameraucana roo, hoping to create some true blue egg laying EEs. The chicks fall into 2 distinct categories. They look very similar to Jaerhon chicks. Some are darker with the white dot on their heads. Could these chicks be sex-linked? I know as a general rule, you can not create sex linked chicks by pairing a sex link breed with a non sex link breed. And I admit I unclear on the difference between auto-sexing and sex link.
