But if the bator is regulated by a thermostat, wouldn't the thermostat adjust for that change?LG, I don’t know what your incubator looks like or how many eggs you have in there but one problem the big boys have, the ones that incubate tens of thousands of eggs at a time, is getting rid of excess heat. The huge volumes of eggs that have put off so much heat they can cook the eggs if they don’t cool them off. But that’s normally later in the incubation, not as early as you describe. Just throwing out a thought.
