Can someone explain how to file their beaks down? I know we can help them file it down 'naturally' by feeding them on slate and adding cuttle bones for them to chew on, but how would you file a young torts beak or an older one? Who knows, maybe someday I'll have to do this and would like to know 'how'. What tools would you use and, how much would you file at a time say if it was REALLY badly over grown?? I'm really curious about this..
