Hello dberes and welcome to the forum! That is so nice of you to rehome an older grey. Thats great the she bonded with you so well, some people aren't that lucky. If Gracie didn't like her previous owners wife for all of those 16 years then I don't think your wife is going to have any luck. Maybe something bad happened to her and she doesn't trust women anymore. The best thing you can do is give her her space around your wife and don't force her to like your wife. Some greys are just one person birds. So does Gracie talk? or make any cool sounds? Anyways, I wish you the best of luck with Gracie and please keep us updated on her progress. If you have any pictures of her we would love to see.
