I just built an incubator. I went with the ice cooler design. I measured the heat cycle with a digital multimeter that has a thermocouple probe. The heat cycle is as follows: - At 100 degrees, the light/heat comes on for about 35 seconds. - During this time, the heat climbs to between 103 and 104 degrees. - The light/heat goes off. - The temperature drops back to 100 degrees in about 2 minutes and 30 seconds. - Cycle repeats. Is this sufficient for incubating eggs or should I change something? Also, what is the best way to maintain proper humidity levels? Thanks a lot!
