My friend had a dog get into her yard and run and kill all but two chickens a few days ago. I came to help her today, since she wasn't sure what to do. The remaining two are in shock. One is not hurt, the other is currently unable to walk. I haven't been able to really assess the injury, but I brought her inside in a box with food and water. She was shaking when I brought her in The remaining hen is out in the coop all alone, now. What is best to do in this situation? I worry about the lone chicken, especially with such recent trauma. With the injured chicken I feel like keeping her warm and still is most important for now, but correct me if I'm wrong.
