I saw that video too, but Justin uses an exact mix of 50:50 vermiculite water that's on the dry side to start with, he just doesn't want to lose the little bit of humidity that's in the tubs. I'm not sure how he deals with moldy eggs or stinky bacteria on eggs, he seals them up and doesn't even check on them for two months. I'm constantly checking on my eggs making sure everything is OK, at least once a day. I'm sure I've saved clutches or at least a few eggs by pulling out the nasty ones and trying to save them in a separate box, so far all the moldy bad ones have gone completely bad, I haven't saved one yet. But at least I get them away from the good eggs.
You say the humidity is on target, do you have a humidity gauge? What are you running at? They looked a little bit dimpled but they still don't look too bad as long as they don't get too dehydrated along the way. You could try adding damp sphagnum moss to the incubator to boost the humidity a little bit.
