Can anyone with more chicken experience - and understanding of flock hierarchy - help me out?? I had an Ameraucana isolated with a Buff Orpington in my chicken tractor for nearly a month because I suspected her (the Ameraucana) of egg eating. We waited until she laid and left her eggs alone to integrate her back into the flock. When I did it, we put her and the Buff in the main coop at night, when everyone was to roost for the night (since I've been told this is the smoothest way to introduce "new" chickens). Well the Buff had no problem with anyone...no one picks on her, and she doesn't pick on anyone. But the poor Ameraucana is getting bullied by almost EVERYONE!!! One Australorp and a Barred Rock in particular run up and peck her on the head and chase her around anytime she comes out of the coop to eat or drink (the feeder and waterer are in the run, not the coop). So the poor thing is trapped in the coop all day long out of fear and she must be hungry and thirsty. I don't know how to make this stop! It's been at least a week, and nothing's changed. Even when they're all out free-ranging in the yard, that one Australorp will run across the yard just to jump on the Ameraucana's back, hold her feathers and peck the sh*t out of her head! I feel so bad, and know this is my fault for splitting up the flock and then putting them back together. What can I do to make this stop??? (p.s. all the girls grew up together as chicks) Thank you!!
