Tiggs

I have finally achieved an ambition I have held for over twenty years and got myself a Grey. He is 10 months old and has been hand reared and is very hand tame with his breeder. Now I have brought him home, he will accept rubs through the bars but doesnt like me trying to touch him with my hand in the cage. He is happy, eating and whistling. I just need to know how easy I need to go with him, he has nipped me once and I dont want him to get into a pattern of if he bites me I go! Any adivce would be gratefully received.
