Today we noticed that our rooster was hopping along instead of walking. He is favoring his right leg and not using his left leg very much. We checked out his leg and foot and didn't notice any scratches, redness or swelling. Any suggestions to what might be wrong with him? He is only about five months old. He is usually a very active rooster running and chasing but he is sitting down a lot and not chasing me like usual! Thanks for any help or suggestions.
