Hello, BYC! We have three button quail--two hens and a rooster-- who have been living happily together since we got them about a year ago. At first, our rooster Manfred seemed to be mated with Ethel, and didn't have much interest in the other hen, Lucy. In the past two weeks, Manfred has become increasingly sexually aggressive with Lucy. He'll chase her around the cage non stop, and has plucked the back of her neck clean. Today, he was especially brutal, and it looks our failure to separate them sooner may have cost our dear little Lucy an eye. We feel terrible. I tried moving Lucy to her own cage so that she could catch a break and recover, but Manfred instantly started going after Ethel with the same aggression. Currently, Manfred is separated in his own cage, but I've read that males don't do well long term on their own. As for what has changed (so that maybe we can correct this/prevent it in the future) -We restricted their light over the winter months and within the last month stopped covering them up in the early evenings. Could this just be "spring fever" and if so, might it pass on its own? -We do have a full spectrum light bulb hanging about 4 feet above the cages as the room they are in doesn't get much natural daylight. I know that white heat lamps can cause aggression in chicks--could this light possibly be the issue? We're not sure what to do next. Here are my questions: -has anyone ever kept a male on his own without him becoming devastatingly depressed? -Is there any chance that we could reintroduce him to the two hens once everyone has healed up? -Is it likely this aggression is permanent, and if so, will it ever be possible to keep him with hens again? Any advice or theories would be greatly appreciated! We're so sad to see the little family get broken up--the only issue we've had until now is Ethel occasionally plucking Manfred's butt feathers, but never to the point of bloodying him.
