My Russian female laid four eggs. They had been in the incubator 7 days when I had to leave town for 2 1/2 days. Somehow, the thermostat did not turn on the heat at some point, so the eggs were at 77F when I got back. I don’t know if they were at 77 the whole 2 1/2 days, or only hours, so I’m going to assume all 2 1/2 days. Of course I fixed the temperature as soon as I saw that. Will 2 1/2 days at 77 ruin these eggs if they were fertile? Anyone had no power to incubator for that long?
