He looks relatively good now, and thank you for complimenting my little buddy Junior. That is his better side. He seems to have a baseline level of feather picking. Sometimes he will pick more, sometimes less. He has no real bear spots but he picks at his wings to the point he cannot fly for years now. Right now he has some red tail feathers, but sometimes those are gone. I do think it might be behavioral or hormonal. He loves to get petted, but I only give him head scratches for years now in case too much touch incites feather picking behavior. A bird vet treated him with Lupron, an anti testosterone drug. This seemed to help a little but it was variable.
Thank you for any advice.
