I am experimenting with a new thermostat that can only be set in one degree increments. It is the most accurate thermostat that I have experimented with so so far but the problem is in a forced air incubator, it will maintain a temperature of either EXACTLY 100* or EXACTLY 99*. I have never seen it once fluctuate in either direction. I am aware that the ideal temperature should be 99.5*, so which is the lessor of the two evil, 100* or 99*? I am fairly sure they will hatch at either temperature. If anyone has any ideas on how to get my incubator to maintain 99.5* please let me know.
