I'm sorry that your question wasn't answered in a timely manner. I need to know if your bird is feather picking or, instead, an abnormally persistent molt exists. The former is more likely and so I'm going to post my synopsis of feather picking for you at this time:
I can understand your frustration at this time. The etiology of feather picking/chewing/self-mutilation can be a challenge to determine particularly if you don't have an avian-oriented vet (please see here: www.aav.org) available where you live. Both medical and behavioral causes exist.
Birds usually chew the breast feathers and areas under the wing and around the legs but any pattern can present. Feathers on the head remain unless a molt or medical disorder is present. Medical disorders include infection with the protozoan parasite Giardia spp. and should be a consideration when picking of the feathers over the ventral (lower) abdomen is seen and zinc toxicosis due to chewing on zinc-plated cages has also been shown to be linked to feather picking. Anecdotal reports suggest that a unilateral (one-sided) pattern of picking may indicate a disease process under the area of picking such as ovarian or renal disorders. Viral infections such as psittacine beak and feather disease or polyomavirus, bacterial folliculitis, dermal yeast infection, or topical irritants need to be considered as well.
Rarely do birds feather pick with external parasites. There are many rule-outs for behavioral feather picking including improper socialization when raised by humans resulting in phobic birds or those with obsessive-compulsive disorders - which should be a consideration when this behavior is preceded by a molt. A traumatic event can cause a bird to become nervous and pick; anecdotal examples abound such as witnessing an attack by a hawk outside the window at a bird feeder, the owner leaving for vacation, a change in the color of the cage, a nervous owner, and the death of a mate or owner. Some birds improve in a new home with a new owner for unknown reasons.
Here's where an avian-oriented vet will be necessary...
All possible medical causes for a bird's feather picking are evaluated first; then if no medical cause is found, behavioral causes are explored or presumptively treated with psychotherapeutic drugs such as clomipramine which would need to be prescribed by a vet. A complete blood count and biochemical profile, blood lead and serum zinc test (Louisiana Veterinary Medical Diagnostic Laboratory can run this test on just 0.1ml of blood and serum), X-rays, psittacine beak and feather disease test, and fecal ova and parasite exam and fecal ELISA test for Giardia spp, if necessary, are performed along with a feather follicle biopsy and culture. Consider the introduction of toxins into her environment as well - the great majority of which can’t be tested for.
General and presumptive treatment includes removing any stressors, improving her diet - it sounds exemplary, however - and restoring what she perceives as a normal environment. Consider clomipramine which works well in true obsessive-compulsive disorders. Distracting her with toys, a "sweater" over the area may help but be sure that she can also engage in normal and necessary preening behavior. A collar isn't recommended as it doesn't allow her to engage in normal preening behavior, normal feeding behavior, and normal movement. A collar should only be used if she's in imminent danger of hurting herself (self-mutilation). Finally, many birds normalize once their molt is complete and so simply "watchful waiting" may be appropriate at that time.
