Hi, I have a hen that is sick. She is a young hen. A couple of days ago she was limping but when I caught her and looked at her leg/foot there were no obvious signs of something being wrong and it seemed to get better. I just went out to the chickens though and she was lying in the shade and I first thought she was dead. When I picked her up she was very much alive but she is very weak. I have her in a crate w/ water. There is a clear discharge from her vent. Does not smell. No sign that I can see of an egg in there. Ideas?
