I would seriously consider revamping your entire husbandry. The enclosure is much too big, temperatures are too low and the snake is extremely stressed out. Yes, they will starve themselves to death if their environment is not correct and they don't feel secure(which he doesn't right now).

How I keep new babies is this:

-1 6qt plastic sterilite tub w/lid
-newspaper substrate(full sheet folded in half, then folded in half again)
-1 4" plastic plant saucer(holds water underneath a planter)
-1 AcuRite DIGITAL thermometer/hygrometer unit(WalMart)
-3-4" diameter water bowl
-Hobby Soldering iron(melting holes in the tub)
-undertank heater or a wired piece of flexwatt
-Thermostat or Dimmer(Johnson Controls/Ranco or proportional for thermostat, and Lutron Credenza brand for dimmer)

Set up the tub like so:


Size of snake in the tub(year ago):



After you move him, you NEED to NOT touch him for at least 2 weeks. He needs to settle in and feel safe.

After 2 weeks, offer a LIVE small adult mouse after you have pre-scented the room(stick mouse in cage next to snake's tub for 30 minutes in a dark room). Do not touch the snake, just open the lid, drop the mouse in and close the lid. Keep the room DARK, use a flashlight if you need to.

Wait for 10-15 minutes, don't worry the mouse is unable to hurt your snake if the mouse is well fed and hydrated(and you don't leave it in there for 5 days obviously). If the snake doesn't eat, remove the mouse, close the tub and wait another week. Repeat the same procedure. NO handling at all in between.

DO NOT handle him at all until he's had a good 4-5 consecutive meals. You're going to have him for another 40 years, you have time
