My BP doesn't exactly "ball"

[MarkS]

Balling up is generally a sign of fear or stress. The ones I have that ball up are the ones that are more skittish or nervous or just don't seem to like being picked up.

The ones that are perfectly okay being picked up never ball up...they just start poking around checking things out.

^^^^^ This exactly ^^^^^

Most of my hatchlings will ball up but as they get older and more and more comfortable with their surroundings, most will stop doing it. However there are some that just never seem to stop doing it and will stay balled up the entire time I'm handling them.
