Sherry, you all will be just fine. The best thing about amazon's is that they are very easy to read, they say what they mean and mean what they say, lol. Take your time. Watch her posture and body language. Find out her favorite treat and for the first couple of weeks bribe the heck out of her for everything she does that is positive. You can worry about dietary changes later. You really want to develop a bond of trust with her.
Like all birds, zon's are very, very SMART and catch on quickly. They are usually very food oriented so that will help. Because of being brought into a new situation, she'll probably be a little docile first, checking things out. Use this to your advantage. After that, she'll probably try testing you by lunging and trying to bite, wanting to judge your reaction to her behavior. Try not to cringe, but do let her know, firmly, that that type of behavior is not acceptable. Be fair, firm and consistant. She'll catch on fast.
I am so very, very excited for you and soooooo jealous. I just love zon's and would so have a houseful of them if I were able to. Feel free to pm me, email me or even call me if you have any questions of need someone just to listen. Good luck, and thank you for bringing this special creature into your home. You are an Angel!!!
