Hey I have a large collection, and i still have issues on feeding some hatchlings, As i have posted on this forum as well. But we try not to handle them after the 2nd or 3rd feeding. If we do it is quick and just to clean or weigh the snakes.
Hang in there.
We got our live feeders on to f/t by placing a live in the cage to get a feeding response, like when they get alert and hone in on the prey, Then swap live with a f/t quickly and zombie dance it and about 90% of the time they take the F/t. We do that a few feedings and then they get use to eating f/t. hope this helps.
