Our established flock of 7 older hens who have been together at least 4-5 years, has started acting brutal towards one poor hen. They pick on her mercilessly and seem to take turns running her off the roost, etc. When they free range, she stays off by herself and hates to come back in at night. This didn't always happen. The picked on bird, Jewel, and the worst offender, a nasty white bird, Pearl, are both originally refuges from a neighbor's flock, who joined ours years ago. Two things have changed in our chickens' routine lately: we added a small flock of 5 week old chicks to the smaller fenced-off half of the coop (where some of the older gals used to enjoy roosting, etc before the chicks needed that space); and we have reduced the amount of free ranging for our older flock since we have had a coyote kill and a hawk attack recently...now they are in their run more often and only free range when we're nearby. What can you suggest I do for the poor tormented bird? I haven't seen any bleeding or wounds. She appears to be heavily molting, which is odd, since no other hen is molting. Perhaps the others pulled out some feathers, and now they are growing back in? We don't have a separate part of the coop for this hen, except for the entrance portion at night. During the day, all the hens would need to go through that area to access the coop. Tonight I caught the main offender, Pearl, and held her calmly for quite a while, talking quietly to her, holding her in front of all the others.......then set her down on the coop floor, standing over her, where she just sat/lay quietly, unheard of for her. Normally, she doesn't allow anyone to catch her (I suspect neglect/abuse in her earlier life before we got her) Do you think I should keep doing this, if she's the alpha female? In 9 years of raising chickens, we've never had this kind of bullying. Help, please!
