I have ten assorted breeds, seven weeks old. The rooster is Golden Cuckoo Marans, the bully girls are both huge Choc Orpingtons. So he is at least half their size, and is fair to the rest of the girls, but trues asserting himself. The Orpingtons chest butt him, peck him every now and then, and will even intervene sometimes when he is being assertive with smaller females. By smaller, I mean his size. THEy are not hurting him, I just thought the rooster is the leader? One of the huge Orpingtons is the lead hen. Does he have to take her crown off or what? She is also my fav.
