I am reintroducing a hen to the flock that was bloodied up on the head and had a cut comb. The comb is now healed and no more blood. She looked pretty good. She has been out of the flock for a month. So I let her out to semi-free range for the weekend and she was getting chased and hammered whenever she came into the group. She finally ended up not going near them and would run if the group came toward her. One or two of them were indifferent to her but the rest of them are really after her. The only way I can see to do this is to just see how she does in the coop. She is doing a lot of hiding in the coop and run. I feel bad for her but they seem to pretty much leave her alone if she hides behind the waterer or behind the nest box. If she comes out they will just corner her and start the ripping out of the feathers. She just faces the corner and takes it. That is hard to watch. I have put Vaseline on her and it seems to be helping a little. My Question is, how long does this usually go on for until she does not have to be terrified? She is not fighting back at all, she is obviously on the bottom of the order. How long does this go on until they are satisfied that she is on the bottom? She isn't bleeding and doesn't have patches of missing feathers or anything, just some of her feathers are looking rough on her back.
