I got 2 barred rock chickens in May 1 of them died to a raccoon. So last Saturday I just picked up two 4 month old Buff Orpingtons and she's been pecking them and they just run away from her. I've been keeping them in a cage in the coop for three days. I let them out to eat grass and bugs and she still doesn't like them. Will she ever accept them or will it always be like this? I don't know her age but she's much larger than they are.
