My 8 month old hen is limping and her ankle is swollen. She's actually a guinea fowl, but I think guineas' feet are a lot like chickens' feet. I'll be posting a thread in Guinea fowl as well. She came down from a tree, at least 5 metres high last night and that was when my mum noticed her limping. She went home though, and fought with the others over roost as usual and today she's trying to keep up with the others. I caught her and had a look and I think she sprained her ankle. What can I do?
