Could someone tell me if I have a Buff Orp/Ameraucana Rooster over a Black Copper Maran Hen, is it possible to get some Oliver Eggers? I'm not sure how the green egg gene carries. The rooster does not have a pea comb. The hens I have, that are the same cross as the rooster, seem to be laying normal brown eggs but some of them do have pea combs. Any speculation as to if it is even possible to get olive eggers with this jumble?
