The real danger is infection so make a nest of wet kitchen roll and leave hatchling in a separate clean tub in the dark in incubator. Sadly once the hatchling has straightened whatever is remaining of the sac will not be absorbed. This is the crucial time either infection will set in or the remaining yolk sac will dry up and drop off. About 30 years ago I hatched a clutch of hermans and several were like this. When I could no longer keep them in the egg I put them in a small heat aquarium with no substrate sitting on blobs of ky jelly I sprayed them lightly with water. After a few days they were dragging their rather red looking sacs around. One of them started nipping at his siblings sac . I went to my vet who gave me wound dressing powder which helped the sacs dry up and I kept them on dry kitchen roll . So every danger of infection if kept in incubator for to long so should have straightened after a couple of days then needs to be moved into a clean environment . Several baths a day to prevent dehydration. Be careful very slippery when wet.use ky jelly so they don't stick to tub or glass and helps to keep infection at bay. Mine survived in fact Nipper has fathered many hatchlings. I wish every success.
