What do you do if your budgies wings arent growing back fully after they are clipped Do you pluck the unreplaced feathers out if so will it hurt the bird?

Never pluck a birds feathers. I dont know what you are thinking. To a bird plucking feathers if almost as painful as if someone were to pull out your hair! Bad idea

Ok, so what can I do if my bird's wings aren't growing back fully?
