Mine at least seems to calm down once I pick him up and have him out of the tank. He seems scared still when he is in the cage and I start picking him up, but seems to relax after a couple minutes. I let him sit still in my hand while he calms down, and try to avoid poking at him too much while he is relaxing. Wrapping his body around my hand seems to help him relax faster than if I let him curl up in my hands. As I'm sure you've seen in the breeder videos, hatchlings may still be nippy even while they are out, and there's always the chance of startling your bp and having him go back into defensive mode, but as long as you move slowly and avoid putting your hand near or over his head, he should be ok. I've also noticed my bp start to "run away" when he is too anxious, and this lets me know he's been out too long. He'll start to move really fast as if he's trying to get away, and it can get hard to keep up with him. It's taken a while for me to learn his body language, so your bp may behave differently and have different signs.
