I just got two new pullets (supposed to be blue partridge Brahmas - one is almost all white though.) They've been through their quarantine period and I'm trying to integrate them into a four hen flock of dark grey (3) and black (1) Orpingtons. The grey hens are attacking the white pullet. The black hen shows no particular interest in either of the new girls. The first attempt at integration was to put the new girls onto the roost after everyone had gone to bed. All was well until I let them out the next morning when the attacks began. It's not just one of the greys trying to prove she's top dog, it's all of them in a gang. Also if the white girl loses a feather, the grey girls fight over it like it's a prize treat. I've actually seen them eat her feathers. The new girls are separated from the original flock now although they are inside the same run and can see each other. I'm wondering if it's her color that is making her a target. Can I do anything to make this work? I wondered if a coat or temporary coloring might work. Any suggestions?
