It really depends HOW crossed it is. How old is he? If you can post a pic, we can give better feedback. Sometimes it can be trimmed; other times, it's just too crossed...I had one that I used to take to an avian vet every 6 weeks for a major trim. She did okay until she was about 8 months, and then passed due to not being able to get enough feed, but I know there are others who have them that they do just fine. You need to provide deep dishes for their feed, because they sort of shovel it in with the bottom beat, so to speak.
