OK< I just got done incubating eggs for a friend. She had penned up her RIR hen, white leghorn hen, and white leghorn rooter together for about two weeks before collecting eggs. Here is what we got: About half each black and white. Some of the white ones have black spots, and two of the black ones look maybe dark brown, but the others are definitely black. she does not have ANY black roos! She has two leghorns, one BO and one EE roo. And, the weirdest part! One of the black ones came from a white egg!
