Firstly Kody is a very sweet little boy. Secondly, I recommend you leave him alone in his cage for a minimum of two weeks before you start to put your hand in the cage again. This way he can settle into his new surroundings. New budgies, can often seem like they are tame straight away but this is because they are scared and can be very submissive the first few days of being home. In the meantime you can sit by his cage and talk to him and get him used to having your hand near the cage.
