My budgie is picking at his feathers. Is that normal?
A budgie will normally preen his feathers daily, keeping them clean and free of dust. So you might see your budgie sliding his feathers through his beak, nibbling at his feathers, scratching his head with his claws, and fluffing up. This is all normal behaviour.
If you find your budgie is actually “yanking out” feathers repeatedly (or yanking out one of his flock mate’s feathers) it’s time to talk to a vet.
