I know Karen Hulvey is one of the very "bird-wise" folks on here....I don't recall seeing her post the last couple of times I've been surfing through here, but I'm betting she would have some words of advice if she sees your post.
If there's anyone else that is a "birdy" person on here, I don't mean to leave ya out, Karen is just the first that comes to mind!!
Do you speak to your grey often? I know my cockatiel has actually picked up a couple of words that he jabbers incessantly just from what I always say to him, lol....every time I walk by him, he either says "hello" or wolf-whistles at me, and he's starting to say, "kittykittykitty", hehehe.
