The LG thermometers are worse than worthless. I took them out and went with my digital therm/hygrometer. Had a great hatch rate for shipped eggs. I trusted the digital because it's readings agreed with how the eggs felt, if you know what I mean.
I had a broody last summer, and when I pulled her off once a day to eat I would reach in once in a while and feel the eggs. They felt pleasantly warm. My LG therms were reading 3 degrees higher than the digital, but when they said the temp was perfect the eggs didn't feel warm enough to me. So I went with the digital and had a 66% hatch rate, my first time, with shipped eggs, in a universally excoriated incubator.
