Feather Picking is a difficult condition to treat for parrot owners and vets alike.
A 1993 study on 28 parrots by Worell and Farber showed: “Certain types of birds, in particular, Umbrella Cockatoos and Moluccan Cockatoos, show very positive and beneficial responses to acupuncture therapy for feather picking.”
Nei Jing Eastern Medicine has been successful at treating a male Eclectus without the use of collars. This parrots case is still ongoing. He is regrowing his feathers, and is not actively plucking.
If the other therapies have not worked. Please consider acupuncture for your beloved companion parrot.
