Parakeet scratching and rubbing his face; lots of white flakes
For the past few weeks (probably more than a month), my budgerigar has been rubbing his "face" on various objects (my finger, the perch in his cage, etc.), almost as if he's trying to scratch an itch. Also, whenever he uses his claws to scratch himself, many small white flakes (almost like salt) fall onto my shoulder or arm.
Is this cause for alarm? What's going on?
Also, my bird eats mostly seed, although he LOVES spinach. Is it bad for him to eat so much seed even if he gets plenty of exercise every day (his wings aren't clipped)?
