Out of 36 eggs 1 pipped and did not make it out, 2 undeveloped past 14 days, 6 fully developed never pipped. The rest hatched about 1 day early. I am mainly concerned with the 6 that were fully developed but never pipped. Incubator ran at 100. The humidity was over 70% when the hatch started and would go up as more hatched. I have heard 70-90% was a good hatch rate at the best of circumstances. Never have had them fully develop and not pip though.
