Hello –
I thought infectrix’s and reps’ advice sounded good, so I’ll just add a few thoughts.
If you have access to live fuzzy or crawler mice (the size with no teeth that stagger around the cage bumping into the snake but aren’t really intimidating), then that would be the best option. Introduce one into the hatchling’s cage at night; if that doesn’t work, next time confine them together in a small container like a deli cup.
I’ve yet to induce any hatchling ball python to feed for the first time by just leaving thawed food with it. They need the food to be warm and to move, at least initially. That’s why it’s so nice to have live fuzzies to offer the ones who just don’t catch on as quickly. It keeps your big, warm, threatening presence out of the picture so instinct can take over.
If all else fails, there’s always assist feeding. If you’ve never done it before, don’t worry, its no big deal and usually quite easy to do. I’ve never met a baby ball python I couldn’t assist feed if necessary. And it can be a life saver with a really recalcitrant hatchling. I never wait until the situation looks dire anymore with a problem feeder. I just assist feed. Let me know if you need the procedure described.
I have a few questions. How much do the hatchlings weigh? Have any of the clutch started eating, or do those four make up the entire clutch? How much do the mice weigh? Have you only offered dead food? Frozen thawed or freshly killed? Are the snakes set up individually or caged together?
There have been times when I didn’t offer food at all until a clutch was a month old. If that photo of one of your hatchlings was taken recently, I’d say you shouldn’t be worrying yet. The baby looks plenty plump with yolk still.
