welcome to our family! I would highly recommend buying your grey from Bird of Paradise in New Jersey! All their birds are vet checked, hand raised and handled daily. They come fronm the best of breeders and they are very careful as to who they allow to buy their birds. Great care is given to their birds and they are the best!
I have 2 greys, a TAg and a CAG. Both are females. I have found and heard from others as well, that a TAG is less timid and nervous. Although my cag is always willing to venture to a guest after she chooses to, my tag won't. But my tag isn't scared of anything. My tag isn't as loud as my cag, but talks and is much smarter in learning words. Alot is just personality in a bird, not necessarily a difference in breed, but my cag is a nervous bird by nature, my tag isn't.
Both are females.
Sorry for the quick answer, have to go off to work. Hope some of that helps.
