Thanks for tagging me!
This isn't bad at all. I was thrilled to see the eggs weren't cut and the babies were allowed to come out at their own pace. The incubator tub looks great. I just have a few notes.
The first is that it's not necessary to separate egg clusters. You can do it as long as they were laid recently, but it's not necessary to pull them apart unless they won't fit in your incubator otherwise. The second is it's not necessary to wash baby snakes after they hatch; as mentioned, any gunk will come off with their first shed. Finally, I would go ahead and move the babies into their own enclosures after hatching, instead of leaving them together.
Otherwise, cute babies!
