Don't give up. Get rid of the aggressive ones and keep getting rid of them. You will end up with gentler birds.I think I might be done. Cleaned everything, rearranged. Put all but injured eye back in. First thing this morning, my original injured is completely bloodied. I don't think she is going to make it. My male is completely covered in blood from attacking her. Blood all over the cage. I put that quail back in there and they tortured her. The male and my aggressive female need to go ASAP. If they touch my nice, polite tuxedo girls I am going to be so upset. I'm pretty sure half of my new hatch is from the aggressive female's eggs. I do not want to watch them murder each other. This so frustrating and I just feel awful.
