I have noticed that Ruby (11-month-old female LSC2) has 3 balding spots. One on either side of her neck and one on her chest. I can only notice them when her feathers are ruffles, or when she is wet. Then I have to really look to notice the spots. When she is dry or does not have her feathers ruffled, I can not see the spots. I am concerned that this could be feather plucking. I never have seen her pluck, nor do I see excessive amounts of feathers on the bottom of her cage, or around her cage Just the normal amount of down feathers. Any ideas or feedback?
