I need help with one of my button quails. He has recently got a wound on the side of his ear and I'm not sure how. He is a male quail and has a female partner. Just this morning I noticed he had a wound now on the top of his head. His wound is still healing but I'm still don't know the cause of the and I'm worried the female one may be pecking him. They are still currently together but and they show no signs of aggression and he needs help. What could be the cause?
