I found this HEN dead today with its eye socket empty and almost half its scalp exposed. They can be rough on each other but we have never seen anything like this. Their cage is secure and off the ground so it wasn't a predator attack. We culled out about 15 males as about 40 birds or so recently matured and some were moved around between our 3 cages. My only real question is would this attack likely be male on female or female on female. I am relatively sure it was a male who did this because I didn't move any new females into this cage. How can I prevent this kind of attack in the future if I don't know which bird did this?
