I have 5 week old quail, cotournix, last week one of the males pecked one of the females so badly her head started bleeding. I pulled out the males from the main cage and put the injured one in her own cage till she could heal some. She healed up pretty well over the next three days, she was very alert and moving around just fine. So i added her back into the now, female only cage. The females started pecking at her head within seconds and she started trying to break through the cage roof. So I pulled her out again. What I don't get is the female runt which is half her size was also pecking at her. Any suggestion?
