My female budgie is 5 years old, in very good health and very happy. I took her to a local vet when I noticed her cere overgrowing. He said it wasnt scaly face which I had already worked out for myself. He said to use an emery board to 'sand' it down. My poor Beaky wasn't having any of that, it would have taken forever anyway! The vet said he couldnt do anything. I am worried it may grow upwards and into the top of her head as it is already growing that way and she wont be able to breathe, is there anything else I can do to help her, any advice would be very much appreciated.
