I am babysitting a chicken named Nalu for the week, and she recently got attacked by a fox. she got attacked before I was babysitting her, but her owner (who is my aunt) had to leave for the week so she left us in charge. Nalu can't walk, so there must be something wrong with her hips or legs. when I try to stand her up, she starts to fall over backwards, then to the side. There are no open wounds or blood, and I've felt around her legs and everything seems normal. She looks perfectly healthy besides the fact that she can't walk. I don't even know which leg is hurt! She doesn't seem in pain, but I don't know for sure. My aunt told me to take her out of her cage and try to get her to walk or run and exercise it as often as possible. I haven't been doing that though, because I think she should rest to let it heal better. what is the right call here?
