I need help! I am relatively new at raising coturnix quail, and I just bought 8 new hens last week. this morning I came home from school, and one of my males was completely bald on the back side of his head. There was quite a bit of dried blood, but I'm sure he will be fine. I noticed one of my hens was being aggressive. While observing him, I saw her attack him. She attacks any hen/male that comes near her. I don't know how old she is, but she is much smaller than my laying hens. Any tips/suggestions please?
