Plucking and mutilating does happen to some neglected birds but also to some that are not. It happens because these birds are not meant to be in captivity. No matter what we offer and supply our birds it's not a normal life and never will be. Frustration from hormones is one prime example. The bird bonds to a human so is never able to do what they are hard wired to do. Many of these birds are not aware that they are birds and not human. It's very sad and as your birds get older and mature you will see what I'm talking about. I see it with Cassie who is 9 and very hormonal right now. I'm sure we will see eggs again this fall and winter. We will watch her moods escalate through joy, frustration, hormonal, anger, aggression and I think even depression. This year she even started doing some plucking on her legs during her molt. It seems to be leveling off as her molt is ending. The fact that she doesn't have a mate to help her with the molt I'm sure contributes. All very sad to watch and understand why. Our lives revolve around Cassie's needs, she always comes first. Many of the members here have similar experiences.
