I have no experience with this but I have heard people tell others that if the eggs are drying to add some distilled water to the eggs. You want the water temperature to be about the same temperature as the air in the incubator. Often people keep water bottles in the incubator to help stabilize the temperature and it is available and the right temperature if needed. You do not want to mess with the yoke though, that is the yellow stuff that is attached to the baby. I think the clear gel is amniotic fluid and really I don't think you want to be moving that much either. I would just add water if your concerned, and if anyone knows more then I do please correct me if needed!
