    I have a very old Hovabator about 18 years old it has the original egg turner and it was still air, so i use a small computer fan blowing upwards, trying to trim the temperature i noticed that if i set the temperature to 99,5 with everything in place (turner-water) but no eggs the temperature is stable around 99.5. plus minus 0,3
    When i put eggs in and the temperature stabilizes after one or two hours depending on the egg turner position (right, middle or left) the temperature fluctuates as much as 2 degrees. I understand that the eggs block the air flow and create turbulence, do i have to readjust the temperature or leave it alone and stop worrying about the thermometer reading after all i read somewhere that the average temperature counts.
    The thermometer is digital very accurate with a tolerance of plus minus 0,1 degree C and it is always fixed on the same spot through one of the ventilation holes just over the eggs.

    If your average is 99.5, I'd leave it alone
