KooKee, our Quaker parrot, started plucking her feathers out mid October. We believe it was caused by the stress of being boarded at the vet while we went to a business conference for several days. Parrot birds are very sensitive and don’t react well to any drastic changes. She’s had episodes of feather plucking in the past, mostly they were hormone related and every time she eventually stopped picking and (with the help of a few drugs) her feathers regrew.
This time around she has not responded as quickly to the medications as she has in the past. With winter in full force we had to do something to make sure our little girl would not get chilled. So I made a sweater vest for her.
