Maybe leave them in the incubator from now on. They need the humidity or they'll get shrink wrapped, and taking one out could disturb the other egg as well as that egg.
Can't wait to see pictures of the babies!! :ya
I'm not really an expert on it, but I just paint over it with one layer and do it quickly.
I think you should seal it, she could make the crack bigger by sitting on it and bacteria could get inside the egg.
I'll add a photo in a sec, just have to find it first.
Edit: I couldn't find a photo...
