Given the time of the year it's probably a CH baby that was recently hatch so I would say a few weeks old.

I would avoid force feeding him, force feeding should be done as a LAST resort and only if the animal has been losing a lot of weight and his heath is in jeopardy, even than assist feeding would be more like than force feeding.

Getting an animal to eat can be tricky especially for new owners, and even more so if they have a very young animal on their hand, but it can be done a lot as do do with husbandry so here are a few tips.

You best bet this is very important if this animal has never ate is to keep him tight and keep him warm.

I would recommend keeping him in a 6 quarts, 15 quarts (max) tub with (1) or (2) 6 inches plastic flower pot saucers for hides, aspen for bedding and temps of 78-82 and 88-92.

Once setup leave him alone for 5 to 7 days (NO HANDLING) and than try offering a live hopper mice (feeding the snake in it's enclosure)
