I adopted a chicken from a friend about 4 months ago. All but one of her chickens were eaten by a fox so she felt bad for the last one and wanted it to be with other chickens. My 6 chickens are a year old and RIR the new one is a Golden Pencil Hamburg. I did all of the things suggested on this board to introduce her to the flock and they got along quite well for the first two months. Now she refuses to sleep in the coop even during crazy rain storms- she stays outside and gets soaked. I'm afraid she won't come in during the winter. What can I do. She is also a bit wild so I can't pick her up or get anywhere near her.
