I would really recommend visiting Dee's site, anafricangrey.ca/forum Its so friendly and informative.
I have a CAG, Grace, who is just over a year old. I am absolutely, madly in love with that girl. She is an absolute riot. It's been a long journey with her, in some ways, but I wouldn't trade her for the world.
I was forunate and got Grace from an EXCELLENT breeder. Grace was abundance weaned, lived with her parents for an extended period of time (related to CAGS taking longer to mature than TAGS), and wonderfully socialized. All the extra TLC as a chick has certainly helped Gracie a ton. She isn't phobic the way greys are "supposed" to be. She went through a phase where she was very skittish, but for the last few months she's been a terror (in a way that I love!) because she wants into EVERYTHING.
I did have a plucking episode with her though

Grace fell off her cage one day and she broke her wing. But I didn't think her wing was hurt at all. Over the next week her barbered/shredded the feathers on her chest, back, and the tops of her wings. I was devasted and took her to the vet. Once we realized what the issue was and got her pain medication her stopped messing her feathers completely. Now her feathers are almost completely grown back. But I'm so thankful that I got her from a breeder who gave her a strong start in life, because I really believe that helped her handle the situation better and not become a picker out of habit. I'm almost glad I go to anafricangrey.ca/forum because of everything I learned there and they helped me help her. And I'm glad I had an avian vet that I trust, because otherwise I may never have known what caused the plucking.
Someday, I think I would like a TAG. The longer I have Grace, the more I adore and the more I think I just "need" another grey. LOL. But I would go with a TAG for my second one for variety and because then I could have a smaller cage.
Grace literally has the biggest cage I've ever seen (in person). It's an Island Macaw cage. And she uses all of it! So when you do get your grey, I would wait until I could afford to buy them as big as cage as possible, especially if you're going to be at work all day. Grace is a pyscho when she's into a toy... hanging from the ceiling, flipping around... she really uses the space...
Sorry to ramble so much, but I ADORE greys sooooo much.
