Like the homemade incubator, did you hand turn the eggs. How's the Bi-metal thermostat with the Flex-Watt? I have a Bi-metal thermostat in my Top Hatch, and it gives me air temperatures of about 98 to 100. It is a bit difficult getting the temperature to be the same throughout the incubator, but I added another fan to it, and now I am not having a problem maintaining even temperatures. I plan for my top hatch to be my goose, turkey, peacock egg incubator.
