I have some chicken with leg problem. They came out yesterday. Some of them cannot stand and just sit. It is not the splayed leg. I think I must have the temp problem, as they came out 22nd and 23rd day. Can anyone tell me if I can do anything to help them? He came out about 16 hours ago, and the one came with him is already runding in the box. When he grovels when he wants to move.
