I think I understand your question.....I have a male CAG he is better with my girl friend. It's not because he's a male IMO it's because his previous owners a female handled him more. I'm a tall fairly big guy and I think it scares him. I would suggest that regardless of the sex you get (remember they aren't dimorphic so a DNA test would need to be done in order to be sure of the sex) that you expose the bird to as many people and situations as you can. I would suggest taking it around people of different races and colors, with hats, with out hats, with/with out glasses etc. From my experience Grey's seem to be more leery of things that are new to them then other birds I've been around so it's good to expose them to new things as young as possible.

thank you for your advice.
