This is my second year using a Janoel 12 incubator. Last year I used the incubator settings indicated in the (very difficult to decipher) manual and hatched 2/6 shipped eggs. The fact that the eggs were shipped and a period of nearly a week when I forgot to top up the water/humidity likely contributed to my low hatch rate. This year, I bought a separate temp/humidity probe (~$30 ExoTerra brand intended for reptile cages) to keep better tabs on the humidity, but it is giving me very different temperature readings than the Janoel thermostat. I originally had the incubator thermostat set at 38 degrees C, but the ExoTerra probe was reading above 39. I then adjusted the thermostat to 37.5, but the temp probe is still giving me readings between 38.0 and 38.4. Does any body have experience with either of these two methods of monitoring temperature who could give me some guidance as to which thermometer I should trust?
