I have a hen that started limping two days ago but she was still getting around eating and drinking. Today she didn't want to come out of the coop with the other chickens at first. She has been out of the coop for a while now and it is nice and sunny her in SE PA. She hasn't moved from her spot in run for a few hours, so I put some water in front of her and she drank a good amount, but I am not sure she is eating. She laid an egg right were she was on the ground. She also has a clear watery stool. Anything we can do to help her?
