The first looks like a pullet to me. Who knows about mixes! I have a chick that looks exactly like the black one. She is half Black Japanese bantam, and half Mille Fleur D'uccle. You would never guess she had anything light colored in her, except a tiny Vito brown up right close to the comb. But then I have another girl like that, same crosses, that doesn't have any brown. So who knows!
