Any other tricks or tips to get hatchlings eating?

[Bogertophis]

Had my first clutch shed out on 11/5/22. Some just took their second meal today. I have 2 that still not eaten. I know it's not crisis time yet where I need to assist feed. But just looking for tips to maybe help get them going.

And for reference I've tried rat fuzzy, mouse hopper, and a asf hopper/fuzzy

Are you feeding live or f/t, or fresh-killed? at night, in dim light? not helicoptering? tried drop-feeding? tried leaving live crawlers in a shallow* bowl overnight (deep enough so they cannot crawl out & get lost in substrate)- many young snakes feel braver when slightly above their wiggling prey, & btw, when feeding live, the prey shouldn't be "too" active, & if f/t, don't get carried away w/ motion- a slight jiggle & moving AWAY from the snake, NOT approaching the snake (which wild rodents refrain from & which tends to scare some snakes).

Some snakes are pickier than others- things that don't bother some may bother the shyer ones, so re-evaluate what you're doing & may be doing wrong.
If feeding f/t- warmth is essential & hairdryers are indeed handy.
