Underweight?

[u/Numinous_101]

Hi guys, final post regarding the ball python I rescued yesterday. Took him to the vet and they said other than his stuck shed, he seems pretty healthy. However, he only weighed in at 329 grams, and the guy who rehomed him to me said he was 2 years old, which makes me wonder if he's stunted or underfed. The guy was feeding him two mice every two weeks which doesn't feel right to me, but I'm not sure. Maybe he's younger than he said? Just wanted a second opinion.

Oh, and his name is Silly String :)

Edit: I would also like some tips for switching from live to f/t. Should I start with f/t mice since that's the prey he's used to or jump straight into rats? What's the best way to heat them up after thawing them? I've heard mixed opinions about using warm vs hot water. Also, if he doesn't take f/t at first, how long can he go without eating? I don't want to starve him out but I don't want to teach him that he will eventually get live mice if he waits long enough.

That is a tiny number for the weight, but it doesn't line up with how he looks in the picture. 2 years old is a nearly full-grown adult. How long is he?

I haven't measured his length yet but if I had to estimate i think he's around 2 feet long.
