Hi Debby and welcome to the grey forum.
My grey Corky is a CAG and we met her when she was 9 weeks old. On our first meeting she ran up the wife`s arm and pooped on her shoulder and when she was 14 weeks old she came home with us.
Corky just turned 13 years old this month and she is vey out going, fearless and will go to almost anyone.
Both the TAG and CAG are great companions parrots and what ever you decide on I bet you will be happy with.
