These chicks came from the co-op. I just don't remember what the sign said they were. I remember one of the bins being marked sex-link. The yellow chicks are from that one I think. The dark one may be a Black Ausultorp. I know they are not the Cherry Eggers. Yes, I know too early to tell gender. These birds are about 2 1/2 week old, I think. Any input would be greatly appreciated.
