It's been a long time since I had BCI's but in my experience they are not shy with handling. They tend to be inquisitive and confident snakes that have no fears interacting with people. BUT, I would still let him settle in first. Changing environments is stressful and you want him to feel comfortable and familiar in his new home to ensure that he's in a positive state of mind. If he doesn't feel secure in his new place yet he may be nippy.
