Feather plucking and self-mutilation is an ongoing problem with many parrot owners worldwide, and can be caused by many different problems.  However, there have been instances where owners have given accounts where feathers have re-grown.  I am appealing for such accounts of recovery, which can be published in Parrots Magazine, so others, who have been affected, may learn from known successes.  You can email me at Parrots Magazine with your stories.
