I'm keeping three quial and this will be the first winter. I have an outdoor cage for them. I heated the enclosed part with a light bulb and it stays about 50 degrees when it drops below freezing. I have two females and one male. Lately the females have been attacking the male. Just kind of bullying, but today I saw a few drops of blood on the males beak. I was told you could keep one male with as many females without problems. They have been together since the spring. Any suggestions?
