I'm on day 19 of my first ever hatch. My temperature has been perfect 99.5 with only a 1 degree variations at times. I am using a hovabator-bator with an electronic egg turner. Today I removed the Turner and added additional water to the tray. My concern was the Turner has to produce additional heat that was helping compensate the heating element. However I left the dial at its current spot. I had to leave for work and returned approximately 10 hours later to find my TEMPERATURE AT 92.3. I have since returned to normal but wanted to hear the experts thoughts. I do not have a fan and it is a still incubator.
