I agree with not handling the snake until it's eating consistently. Leave the snake completely alone for a few weeks except for water changes and try feeding it again. Most snakes will eat f/t if they're hungry enough but you can feed live prey if you wish. I don't see any advantages to feeding live but to each their own. I don't believe snakes "enjoy the hunt". They only hunt to eat. There's no emotion involved. It's purely survival and they're especially not "hunting" in captivity. I hope your critter gets on track soon.
