Hi folks. I came here a few months back for help and want to give an update in case it helps someone else. My Congo female started plucking her chest and stomach bald, sometimes causing bleeding wounds. I tried everything including Haldol, but she continued to get worse. Finally I figured out it started when I'd bought her a freestanding perch, placing her on it a few hours a day. When I got rid of it and returned to leaving the cage door open so she could go in and out at will, the self-mutilating immediately stopped. Several months later, she's regrown most of her feathers. Unfortunately the easy-going bird I've had since she hatched 33 years ago is now easily stressed by things that never used to bother her. Car rides, noisy motorcycles outside, and being kept up too late now result in a few plucked feathers. Maybe the Haldol is what changed her personality, I don't know. Sorry I tried it.
