My eggs are on day 18-19 now. I took them out of the turner this morning and layed them on cheesecloth on the grate. They are staying the correct temperature, but there is a lot of condensation on the viewing windows. So much that I can't see the eggs through it. I lifted the cover to check the temp and when I did the water dropped off the glass and onto the eggs. They also had some lighter condensation on them before I took the cover off. I don't know how high the humidity is in there. I've had some condensation for a few days, but just around the edge of the viewing windows. I probably shouldn't have opened the cover, but I wondered what was going on in there that made it change so fast. Any thoughts?
