Ok, someone else said this too. they eggs were stone cold. Does that part matter? How do I tell if ther eis anything alive in there? jsut mark where theya re and see if anything gets bigger? Well, on the eggs that arnt marans, cant see into those marans suckers.don't lose hope. If it was just overnight and you caught it in the morning, they may be totally fine!! I lost power to my incubator one hatch for 15 hours. I had a normal hatch even though I thought they would all be dead.
