I have an very old Painted Finch his beak crosses over like sissors, I have been on the internet and they say to cut the end which I did just a little bit with nail clippers. His beak still crosses over a bit as I am not sure how much to trim. He seems to be blind in one eye, he still enjoys the aviary and sitting in the sun but with his beak like that would he be able to eat okay. Any advice would be appreciated.
