Baby Balls can be very sketchy and prone to defensive strikes. Usually once you get them up out of their tubs they chill out. Over time they will start to relax and tolerate handling much better.
Keep in mind that just because your Mojo may be 9th generation captive bred, he doesn't know that...all he knows is that he's small and near the bottom of the food chain right now.
Personally, I've only ever known one BP that stayed that nippy into adulthood, and I'm pretty sure that particular snake was possessed by something unholy![]()
