Everything was fine when I left for school, and then I come back and find one of my hens with a bad limp! She was just great when I left, but now she refuses to walk around much but still eats and drinks fine. It's her right foot. It has a small fresh wound which looks like it was scraped, halfway down her leg. This doesn't bother her when touched. She just can't put much pressure on her right leg. I'm really worried about her and I already have too many things to worry about....did she just maybe sprain her leg? What do I do?! I took her in the house in a bin but all she wanted to do was get back to the others. Please help!!!
