I am so frustrated! I rescued a hen three months ago, after quarantine we tried to integrate and my girls would not accept her. She was an only chicken at her prior home, and is terrified of chickens, doesn't know how to behave. One month ago I purchased a pullet to live with her, in hopes that I could integrate them together later. They bonded well, no significant problems. The two new hens have been in a side by side run with my other girls so that they can see each other, and they have their own coops. Yesterday we combined the flocks, and while the hen I purchased is doing fine, the rescue hen is being beaten up by my girls. They sense how scared she is and go after her. She keeps escaping the run and hiding behind our trash cans, shaking in fear. I don't know what else to do with her, we can't maintain a separate coop for one hen! She doesn't even lay, she has only laid one egg since we have had her, she's too stressed to lay I guess. Everything that I have read says that they will eventually integrate and work it out, but this hen is neurotic! I'm don't know if anyone has experienced this before, but I'm out of ideas. Short of giving her back, or just letting her get beat up and hoping they stop eventually. I'm afraid they will kill her though. Ugh, crazy hen.
