He's eating fine.
I have started my own hatchlings before and felt confident in my ability to start him
or I wouldn't have done the trade.
It wasn't from a "reputable" breeder but a smaller local person who will back up the animals genetics
in a heart beat, so I did the trade.

He is doing fine and has a good feeding response now after eating twice on his own.

You presume the snake was stressed out?
Actually I believe it was held too much before getting it feeding.
When I got it he mentioned it liked to be held.
I handle my hatchlings as little as possible till they eat a few times, maybe it's just me, but it seems to help them start better.
