Quaker Parrot self mutilating
I have a two year old Quaker that was given to me by someone who didn't want him anymore. He had a small patch of baldness on his neck when we got him and the previous owner gave me some liquid aloe gel to put on the spot but I never did because I knew the bird would lick it. I read that one of the personality traits of Quakers is that they pluck and self mutilate. There is no pattern to his plucking, he did it when his cage was covered at night, he's done it while sitting on my shoulder. He gets a good diet and lots of love and attention.
The small bald spot has gotten bigger and is more down the chest now. Sometimes he plucks and picks so bad that he bleeds profusely. When that happens I try to soothe him and cover the cage so he calms down. A collar won't do any good because if he can't get at it with his beak, he uses his feet. It's not an every day thing, I would say it averages about once a month.
He can't be bored because I'm with him all day and I know it's not any type of stress because we have a good routine and he pretty much has the run of the house.
What do I do if it gets bad again and how do I prevent him from doing it?
