I have two male love birds. Muffin, the oldest has begun to pull out his feathers. Three vets and all tests proved him healthy. Now, his male cage mate is "helping" him by pulling out the face feathers he cannot reach! I noticed he stopped masturbating about the same time he began to destroy his feathers. Would it help if I got him a female mate? Has anyone had two males with one female? Do the males fight?
