I've been reading that you can trim/file down the beaks, and i want to try it on my little cross beaked, however i haven't found a "right" or a "wrong" way to do it. can someone give me instructions, or point me in the right direction, so i know what i'm doing when i try this? I'd hate to hurt her somehow by doing it wrong, i'm hoping she can eat a bit better this way, she's doing pretty good, but still not as big as her siblings.
