Please help. I'm not very experienced when it comes to raising chickens. But started with 3 in 2014 and now have 8 and 1 rooster. He was crowing just like normal this morning and at about 12:30 in the afternoon, I looked out and saw him laying on his side in the run. He's still alive, but one claw is spread out and the other pulled together. He can't seem to get up. Any suggestions what it might be? Mine are not free range as I live inside the city limits but on a large lot with privacy fence. I was leaving for an interview when I noticed him, and had no way of doing anything for him at that moment. I am so worried, and just heartbroken and so afraid I might lose him. Can a vet help me you think? Any advice would be greatly appreciated.
