We've made slow progress integrating a 1 1/2 year old buff brahma hen into our flock. Now that it's cold, she's sleeping in the main coop on the roost with the others. The problem is, she won't come out of the coop. She stays on the roost while the others are in the run. Whenever she moves, the rooster pecks and bites at her. She's had her tail feathers pulled out continually. I've covered her back end in blue kote. The hens seem to be accepting her but the rooster is so mean! I thought he was the protector. Any thoughts on how I can protect her or make it easier for him to accept her?
