Hatchling Hide question.

Is a deli cup with hole cut into it for an entrance a suitable hide?

This is what I am currently using and they don't seem to like it, they are moving it around and not going in. The corn snake is fine with it but the BP's don't seem to care for it. Should I just go out and buy small hide's from petsmart?

You could try something darker and really snug fitting. Like a mini cereal box with a door cut out. Or some type of small box.

My rack is dark and I use 6qt tubs so I don't use hides and all mine are fine.
