Two days ago, my alpha rooster's left leg became a little limp. There is no obvious injuries. It lasted for two days i thought he would recover eventually. But when I open the coop this morning to let them out, the Alpha could even barely walk. I wonder what could have made it worse? What should I do? It is a very proud rooster, very protective, although he couldn't stop a hawk attack 4 days ago which the hawk killed my favorite little white hen.. At the time of the attack,, I didn't know whether the Alpha put up a fight,, but he did look okay after that at least for the first day he walked OK. He became limp on the second day. What's going on?
