I have conflicting thoughts about this.
My RTB, (which is certainly not a Nic) ALWAYS uses her hides. Unless its close to or after feeding day, then she will camp out on either hot or cold hide and wait for food
Give it a shot but I wouldn't be suprised if you have to put them back in. Snakes like to hidethe only ones who dont are the massive ones who dont care because they are big enough to defend themselves/dont have predators
Good luck!
