Yesterday morning I went to feed the chickens. However, I noticed that the hens and even the roosters were walking over her and she wasn't standing up and they kept pecking at her. She didn't do anything and just let them do that to her. This morning I went back again to feed them and I found her lying on the ground breathing slowly and had blood on her face and legs. Her legs does look a bit pale compared to the others. She doesn't want to eat either. I'm from North Carolina and it has been hot lately. I change their water everyday because they always walking on it and in the end of the day it's dirty. Is she dying or sick?
