Yes, they naturally find places like that to hide just as they would in the wild. It is very important to provide a tight little snug hiding place or two for it down on the substrate so it can hide and feel secure there as well. Small upside-down coffee lids with an entrance notch cut out in the side work well for this as tiny hatchlings, and BLACK TV dinner trays (or anything similar) with a notch cut out work well when they get a bit bigger. The lower the profile the hide is, the better for them to feel secure and hidden. This is very important for the general well-being of the snake,...especially when very young and small. This actually helps many reluctant hatchling snakes to feed if they don't feel "exposed" to predators.
