You CAN properly start a hatchling off in the enclosure it will eventually grown into, BUT you're going to have to take some steps to make it work. I'd say at least one, if not two extra hides depending on the size of the hide and how much space you have. I like using half logs and hollow branches not as hides but as tunnels between them so the snake has paths to get around the enclosure with minimal exposure ( keep in mind the width your snake will grow to, you don't want a hollow branch that they end up getting stuck in as they mature). Limit the open space overhead while simultaneously giving it an interesting environment to explore by adding branches, and lastly fill in any empty spaces left with plants; either plastic ones or real ones in potted planters, just make sure they're reptile safe either way. It will look nice to you even when the snake isn't out in the open, and it will fill in what would other wise be a big open void that the baby's brain would interpret as "predator shooting gallery, BEWARE".
