One of the chickens is looking so weak during her moult . The other chickens saw it and took advantage over her situation and they pecking on her all the time. Now she just sitting in the coop all day she afraid to go outside not even for food or drink. I tried to force her to go out with the rest of them under my watch she just froze in one spot and after few minutes she run back to the coop and hide. I'm feeding her separately and let her rome in the yard by her self during day time. but it's breaking my hart to see her like that. I don't know what to do any more. If any of you had to deal with a situation like this before. please help!
