OK,,, I do have a serious side also.. I suggest you slip in a couple unfertilized eggs into it and check the temperature after running it 2 or more days. Then compare the temperature on your thermometer reading with what the setting is set to. Adjust set temperature to your desired temperature that you get on your remote thermometer. You may have to set it to run At 95°F or whatever

on your setting, to achieve the desired 100.5°F INSIDE.
I have a feeling, INKI may have a tendency to run a LIL HOT

according to the reviews you read.
After your fine-tuning, toss those eggs, unless you are feeling LUCKY,,

On a second thought,,,,, cook the eggs totally in boiling water, and serve up to your chickens. Crack open and see if ok for them

I think doing as I mentioned above would solve that dilemma.
I have other options up my sleeve, that would require external control. but that is another option that would be best to not have to take.
