Help please! We rescued five chickens last year, three of them are ex-battery hens, roughly four or five years old. They are free range during the day and have all stopped laying. When I let them all out yesterday morning, one of the ex-battery hens had lost quite a few feathers. She seems to have the little new ones poking through underneath so I put it down to moulting. Same again this morning though, she's lost even more, isn't hanging around with the other girls, instead preferring to stay inside the coop, and her tail is pointing down :( There's no evidence of mites, although I'll check again tonight when it's dark. If she was just moulting, she wouldn't look so miserable, would she? I just feel so sorry for her. Any ideas would be greatly appreciated!
