Hi, I need help with the correct temp. I have a Hovabator , with a fan and egg turner. The thermometer that came with the incubator reads 100. It is on the egg turner , just about beneath the fan. I have a digital thermometer , a bit away from the fan which reads 90, and a third digital thermometer at the oher end which reads 92. Which one do I use? Where is the proper placement of the thermometer? Thanks All.
