We just bought an African Gray yesterday. He seems to adore my husband, but doesn't let me touch him. I know he will need time to get used to us, but I don't want to let him control me too long either. How do I start gaining his trust and love. He seems to be getting comfortable already. He is chattering and whistling. He is 3-4 years old we think, but has not had enough attention at his previous home.
