Well, as much as I tried to guard against it, we had a spike today. My incubator is made from a wine cooler and there is a light that comes on when the door is opened, but it can also be activated with a separate switch. I was not home and we had family come in and my daughter turned on the light so they could see the eggs in the box and forgot to turn it off. I could have done the same just as easy. Apparently that bulb throws a little heat because when I came home and checked the incubator, the light was still on and the temp was 94. The whole timeline was probably a span of not more than four hours and I am certain it took some time for the temps to climb to that point.
I have read other threads regarding spikes but many have had a more dramatic swing or duration. Has anyone experienced a similar spike in temp and duration, and what was the impact, if any? BTW, today is day 12 so we are pretty early in to this. Appreciate any responses.
