A little over 7 weeks ago, I hatched out some coturnix quail. They turned out to be 9 hens and 2 roos, which I kept together in a 3' x 4' cage in my sunroom. Well, about a week ago, I went to refill their food and water and saw that one of the roos had been badly scalped. I removed him from the group to a cage by himself, where he has been recovering nicely. I figured maybe I made a mistake by keeping the two roos together past 6 weeks of age, and hoped to not have another problem. Then yesterday, I heard a bunch of commotion and went to check on them, and all of the quail were freaking out, trying to get away, but I couldn't tell which quail they were trying to get away from. I then noticed that one of the hens had her neck area badly cut open. I removed her and put her in a separate cage, which now leaves me with 8 hens and 1 roo in a 12 sq ft space. Any ideas of how to deal with this situation? I am experienced with chickens, but this is my first attempt at raising quail and I don't know what I'm doing wrong, if anything. The breeder I got the eggs from says the last time she had to cull a quail for aggression was six years ago, and she hatches out a ton of quail, so I can't imagine that the line of quail that I got would be particularly aggressive.
