I have a 10 year old lutino cockatiel, Sunni, who has been picking out his feathers since he was one. When it started, I took him to the vet who said he was healthy. She also said lutinos were more nervous than birds of other colors. I had noticed that, because one night, he was sitting on my shoulder when my power went out. The next thing I heard was a little gasp - and it wasn't me! I got a lantern on and he stopped gasping.
She gave me a spray which had mainly aloe vera in it and I sprayed him daily. He didn't like it and it didn't help. After awhile, I stopped, because I read that picking alone wouldn't cause them to be sick and I felt that the spraying was making him frantic. I tried giving him extra attention, but it didn't seem to help either. Since he came home, his cage has been open, but he won't fly from it unless he sees me. He loves perching outside on the top and looking out a window. Lately, he's been picking different areas and now he's making me frantic. Besides the spot on his belly, he's branched out and done the inside of his wings and now he's started on a shoulder. I can spray him without his getting too upset now, but he really only likes it when it's hot out.
Maybe there have been advances in the past 10 years. Does anyone have any advice for us?
