I need some help. I have 30 coturnix quail, 5 males to 25 females. They range from 8 weeks to 9.5 weeks. Yesterday I came home from a baby shower to find one of my males missing all the skin from the top of his head. I went out this afternoon to check on him and the others, and found one of my hens missing about half the skin from her head. Their cage is only 12" high and they're in the garage so nothing to startle them and make them hit their heads. I'm assuming it's one of the other birds. I just can't figure out who. All of them males are rough with the hens, and I have one hen that's just a jerk to everyone. I'm not sure what to do at this point. The male that was scalped is separated to keep the others from pecking at him, but the hen is not. She wasn't as bad and I don't have a third cage to put her in alone. Any help is much appreciated!
