Is the fifth snake from one clutch still hiding?
Sorry if you already posted about this; it's harf to keep track.
If still missing, well, that seems like spicy behavior?
I don't think it was specifically spicy behavior so much as it was natural instinct to disburse combined with bad luck being in an incubator with a hole for a thermostat probe big enough to let a baby snake slip through. It's not like they intentionally ran away, they just did what nature dictates a baby snake should do.
I'm hoping they'll turn up before they get too dehydrated. I've been looking for signs but they often curl up somewhere safe until their first shed so they might be tucked in a nook and not moving.
