Anyone have any ideas why a parakeets beak constantly gets over grown? I have read it might be linked to the liver? Should I take her to a vet for bloodwork? She is so small I worry that might do more harm than good. She is constantly picked on by my other birds and I had to separate her from the others. I take her to a vet to get trimmed and the vet has never mentioned anything. She has access to cuttle bones and whatnot but her beak needs trimmed about once a month.
