Snow corn as a gift, general question

[Jakeslither]

Apologies if this is in the wrong forum

so last night, I had a friend who told me of a guy here in town who had a 20 gal/40 gal terrariums with decor, hiding spots, climbing branches, heating pads, day/night bulbs/lamps and a snow corn snake.

Basically the previous owner landed in Hospice care and could not take care of the snake any further

Now I wanted to raise two babies..but the equivalent of $300-$400ish I was of course not going to hesitate on the opportunity!!

he/she initially hissed before I got him/her out of her enclosure to a carrier tank to take home (picking the bigger terrarium up later today) but has since seemed to calm down


the guy who had the snake in the house said he hasn't handled him/her since the owner went into Hospice

now there is some advice I wanted to ask, the snake again isn't hissing at me currently, but when I attempt to see if he/she is docile..the snake will curl up into a corner..given it's probably still stressed/getting used to the new environment I understand..again no hissing

but I'm wondering how best I could take steps towards handling/finding out if he/she is docile enough to keep as a pet.

I'm assuming the snake is captive bred previous to the owner but I can't know that for sure either.
