Day 2 of incubation. Trying Chooks dry method from her tip sheet. Lg bator, dry air. Temps are holding good at 100.5 (Its set at 101.0. Humidity is at 40-50 percent. Its in a walk in closet with no air movement or changes unless I open the door. My question is, my 2 cheapo thermometers state the temp as 98.0. They both agree. The bator states 100.5. Do I add a plug or 2 and try and get the aquarium thermometers to read higher, counting on them to be more accurate since they agree?
