So, I just came back from a week long vacation and my neighbor who also has chickens took care of my flock. When I got home it was late and they were already in the coop. The next morning I came outside to give them some treats, they all ran over and my rooster followed his girls. I noticed him running weird, like almost skipping, I also noticed he walks with a slight limp in his right leg, and when he stands still for a while he'll occasionally lift up his right leg for a few moments and put it back down. Any ideas what could have happened or what I can do to fix it? Any help is greatly appreciated.
