ok, that's good. any eggs you have on the bottom might be earlier than the ones on the top rack. Hope you have a good hatch!Built in readout stays the same I adjust the calibration it stays sitting at 37.5C and I rely on my two thermometers to make sure temp is running right. Don’t worry the are right I stuck the probe in a cup of ice water and left it there for a good while and it read 32.2F and bottom reads 100.4 and top at the most I think it reads 100.8 but just for a short while and only seen it one time I they were still stabilizing
