I have an 11 week old Buff Orpington Hen, who while the runt of the flock is mean. She charges the roosters and goes to peck me anytime I go to pick up any of the hens. Is this something she will grow out of? She has been somewhat of a little scrapper since day one but I thought this was supposed to be one of the better tempered breeds. Any thoughts to help make her nicer?
