This morning I went to feed the pair of button quails and found the male had plucked all the feathers off the females back overnight!!!!!!! They have been living together with no problems for many months. I was shocked how many feather he pulled out of her in such a short time. Why did he do this? I thought they were happy. They are tame and will come running to the door when I open it to add new food. They have lots of hiding places and a big dust bath - get chick started food, egg food, seeds vegetables and have grit, oystershell and cuttlebone. I keep another group of button quails in a colony with several males and females living together (which I am told will lead to fighting). However they are all in perfect feather condition and laying lots of eggs with no fighting. They are also less tame than the single pair and quite flighty.
