After a bath today I discovered that one of my Conure's wings has a bare patch hidden under a primary feathers. The patch is on the top of the right wing, where the first 2 primary feathers are. She has been preening small down feathers but mostly on her chest. Is this a natural part of her molt? I haven't seen her plucking but perhaps she has been? I am very worried for her and was wondering if anyone else has seen/experienced this? She is a healthy bird otherwise, her vet gave her a clean bill of health a week ago.
