I adopted a young macaw about 2 years ago. Her name is Maria and she is dna'd female and we are very bonded. I used to work with all kinds of parrots and would take her with me to schools and do educational programs with her on occasion But she never really socialized with the other parrots bc they had been a flock for years and just didn't like her..she started pulling out several wing feathers and lost so much blood she almost had to have a transfusion twice in one year but the incidences were months apart with no plucking between. She recovered both times after week long hospital stays and lots of test and still no answers. I got a new job and am able to spend more time with her at home but it's just getting worse she went from beautifully feathered to a few weeks later having a bare chest and constantly preening and plucking...she cries out when she pulls them out but goes right back at it.she even wore a cone of shame for a while.but no matter what I've tried and how many vets I've seen we haven't been able to help her its just getting worse. Ive worked with macaws my entire life and have never seen this from a bird that has no history of poor diet or improper husbandry. Several thousand dollars in vet bills have gotten me nowhere I Dont want this for her and she is obviously distraught even when being held and cuddled, she won't stop compulsively preening and plucking. I'm desperate for advice, and have been researching holistic treatments and am even considering keeping her on an anxiety medication one vet gave her for her recovery after a hospital stay. I hope someone has an idea we haven't thought of
