Ok, your bp is very young and very stressed right now. New enviornment, new smells , new living arrangement. All this equals fear and defensive behavior by the youngster. It's always a good idea to just observe them once they are placed in their new living quarters until they have settled in and taken 3 or 4 meals. Definitely going in and taking them out of their hide is a no no. The hide is where they expect to be safe and untouchable. It may be ok to do that to a established bp but a young bp is very fearful and their only defense is to hiss and make themselves sound and look bigger. And also to snap and bite. So, for now, just go in to change water and spot clean. No more handling at all right now. The little girl needs her privacy and security. Good luck.and you have handled her way too much at 4 or 5 times.
