Our neighbors/relatives are leaving for the week and left us in charge of their chickens. We were told that a fox had attacked recently and had killed their rooster and injured one of their hens. We have decided to bring the injured hen ( a barred rock) into our barn to keep a closer eye on her. We inspected her and found that she only puts weight on one leg, and will not walk. On inspection I do not see any leg injury. I may need to check again though. I have not observed her eating habits or weight yet but she does seem alert and perky besides not being able to walk. I don’t want to take her to a vet since my parents probably would not allow it. Any advice for what we can do is appreciated. More info will be given if needed, we just found out about this.
