Tweety Take Flight

Tweety took flight today so wings got clipped this is at 40 days old. Just about all of his feathers have grown out.. there are still a few bald spots on his wings. For some reason his father plucked out the feathers on his wing and broke ALL of his flight feathers to the point that some were bleeding. Does anyone know why his father would have done that? I thought that maybe it was because Tweety may be a male and his father didn't want the competition.
