After mapping out the entirety of my still air incubator, I have found some cold spots (furthest from the turner and heating element) and some VERY hot spots. The coolest spot was 98.1*. The hottest was 104.7*. There are several places where the temps vary. Some measured at 101* while others were at 99.1*. I'm probably going to put all the eggs on the outlying 99.1* and the 101* and try to stay the heck away from the 102* areas. I think I finally know what happened in that incubator... I've tested the thermometer 3x now. I have a feeling it's more accurate than the thermostat in my place. When the AC kicks on, the thermometer is at 77*, whereas the thermostat says 76*. The AC is set at 76* so it doesn't make much sense for the AC to kick on AT the temperature it's set at... Which means, my incubator was running 1-2* high for a proper incubation. Hopefully this batch will do better. Am I wrong in assuming the "cooler" temps are the safe bet? I'm so scared after 3 incubations that nothing is going to hatch again.
