One of my chickens has recently gotten wry neck, I believe either because she wasn't eating enough possibly because another hen was being aggressive toward her. I've been giving her vitamin E and Selenium for about the past week and a half and have been letting her free range outside. I've experimented with putting her back in the coop, and the hen that was being aggressive toward her was separated during one of these experiments. When that hen was separated, all of the chickens got along fine. Her body is still very bony and less muscular than that of the other chickens, but she has been eating occasionally inside (which is where I've kept her at night) and in a cage located in the coop that she's protected from the other chickens in. She eats the most when she's free ranging and in the coop with the others. She's still weaker than the others and has some trouble going over obstacles. Any advice on what I can do to help her get back into the coop permanently and how I could make the transition of putting her back in? Any advice is appreciated.
