Eggs hatched early

[chubbiechicken]

I had 30 eggs in incubator 1 hatched day 19, 6 hatched day 20 and day 21 5 fully delveloped but dead and the rest not even fertile! I'm feeling disappointed but happy with at least haveing 6 babies doing great! I'm thinking my humidity was too high during hatch?

Still air or Fan? Large fowl or bantam? What were the temps and humidity? Early hatches usually indicate slightly high temps, though bantams, in my experience, tend to hatch earlier.

Fan, large fowl.. I couldn't get my thermomiter to go but 89.4 or 101. Nothing in between.. I kept it at 89.4 and humidity at 50% incubation and 60-70% hatch.. All the unfertile eggs where scrambled when I cracked them
