I tried to look up how old my eggs were in the spring when they went without heat. All I mention in the May HAL is "They've survived being left open twice with no heat; once for the day and once for about 4 hours." And those were in my incubator. The day we did taxes I turned it off and opened the incubator when I turned the eggs...but I forgot to turn it back on and shut the lid before we left.
But everything was fine in my case.
I also had broodies switch nests and one nest of eggs were left uncovered all day in 9C weather. Eggs were ice cold when we got home at 2am, no movement at all from the embryos. I put a broody back on the nest and everything was fine.
I'm thinking you'll be fine.
