Sorry Anna about the biting. Is your grey, what is his name by the way, only biting you? Have you been doing something different then normal? Without knowing the situation it is only guess work about the cause. My baby grey, Ana Grey, 9 months old, is a sweetheart, most of the time, but occasionally she will nip at me because she doesn't want to leave the top of her cargo net when I want her to. I then back off and wait a little while. If she still doesn't come down, I offer her a treat, peanut or pecan nut, which she totally loves, and that usually immediately gets her to come down to where I want her to. I am the only one who interacts with Ana Grey now so her bite is what it means, "I don't want to, go away." Sometimes they just like alone time and I try to respect that if I can. I don't know if this helps you, but they are intelligent creatures and unfortunately sometimes have minds of their own. I'm glad you have decided to join the family. If you have any pictures of your grey, we would love to see him. Welcome to the family!
