He is young, is there a way I can put a stop to this or does he need to go? 17 weeks old. Nobody is mean to these chickens, chasing is not allowed. My other rooster and all my hens are mellow. Once I pick him up he is fine. Settles and I can pet and talk to him. However, he has attacked both my grandsons and the littler boy got it twice in one hour! Food should not be an issue: Free range dawn til dusk. Chick starter in coop.
