Well, just had a perfect hatch from my last set of eggs. I had taken all forms of moisture out of the bator and hatcher after the last drowned-chick hatch and it was a week between hatches so these last eggs had a full week to dry out and it worked like a charm. I am very confident now of setting this next hatch without water. And yes, I weighed each egg separately, I am way to OCD to just weight the tray and take an average, that wouldn't work for my Excel spread sheet. Besides, I only have about two and a half dozen eggs in there.
