What incubator do you have?
My guess is that the temp drops at night and the incubator cannot keep up.
It is one of the higher quality Janoel8-48's(not the knockoff). But i figured out the problem...somewhere early on i somehow set the temp to 36.5c which i just realized yesterday is only 97.7f....it was suppose to be 37.5c

Thank you, the current batch is staggered so i dont think i will lose them all the khaki campbell eggs are only on day 7 today third set of frizzles/frazzle are on day 8. Probly lose my muscovy and another frizzle/frazzle. Muscovy were doing great but when i candled them Monday night the eggs didnt look right ot me anymore, so i dont know if i had alot of late stage deads or what. The eggs dont smell, yet.@misfitmorgan I hope you figure it out quickly so that your the current batch ends up ok!!![]()
