Running a dry incubation in a Hovabator w/fan. Have a bulb thermo below turner and another on top of eggs. Both read consistantly 100.0 degrees +/- what the naked eye can't see. My digi thermo at about mid egg range consistantly reads tween 98.2-98.8. Just been leaving thermostat alone calling it a happy medium. Can anyone suggest anything different or am I on the right track?
