I have a rooster that is about 7 months old. This afternoon when I went out to the coop I noticed that he was standing on one leg and refused to put any weight on the other leg. He lets the lame leg just hang down and doesn't really tuck it in like normal. He is able to move the leg itself, however he doesn't seem to be able to move the toes on the leg. He is obviously not motivated to move much and just stands on one leg in the middle of the coop floor. When he sits down he lets himself flop down and then sits awkwardly on his side to not put any pressure on the side with the injured leg. When he is standing he tucks his tail way down and is definitely not a proud rooster at this point. I had not noticed this before this afternoon, however I do remember him roosting on the lowest rung last nite which I thought was strange, but could have been because he couldnt get up any higher with an injured leg. Is this an injury, infection, or something else??? please help!
