So how many thermometers/hygrometers are in YOUR bator? I was doing pretty well with temps but yesterday they started going all over the place, so I bought a third therometer. Today the two hygrometers were wildly different and none if the thermometers agreed, so I bought a fourth. Unfortunately, it seems to confirm the higher temp readings from another thermometer and now I'm afraid I'm cooking eggs instead of hatching. Ugh!
