Thanks everyone.

He's not a hatchling. I think he's a few months old.

But I need to feed him in another enclouser because of the bedding - it's aspen. I read that it was safe. However, I can change it to something else once he calms down if that would be better.

Could I just put the mouse (thawed, I like to feed my snakes already dead mice) in a container and put that entire thing in his cage and just let him get in there and eat it and remove it after?

Thanks again.
