I put a water wiggler in the incubator this time to see if it will help my hatch rate and have a question for people who use them. Do you go by the temperature from the probe in the water wiggler or the temperature of the air? I have calibrated the probe in the water wiggler with a medical thermometer so I am confident it what it is saying but there is a difference in it and the air temp. The water wiggler is saying 99.4 (after .2 adjustment) and the air temp is reading 101.8.
