Babalu's beak use to have a big edge on it, or like a little step going up towards his nose, very uneven... hard to explain, hope you get what Im saying, hehehe. Anyway, it looked similar with the white but not as much as Pepper's. When I took him to a bird store I asked the owner his opinion on if I needed to have it filed down, they said no and recomened the sandy perch. So I got the sandy corner perch and he has smoothed it all out himself over a few weeks.
