I set a mixed batch yesterday in my Hovabator 1583 with auto turner. I have two glass thermometers and a digital thermometer/hygrometer combo. I'm maybe driving myself a bit more crazy than I need to, but the digital thermometer is a consistent 99F and 35-36% humidity. However one glass thermometer reads a minimally fluctuating 99F-100F and the other one reads 100F-102F!! The one that reads higher is the one that actually came with the incubator. Which one do I trust?? Do I add yet another to check?? Am I driving myself unnecessarily crazy with it? I'm worried they're too warm.
