I was wondering if you guys who incubate could tell me what thermometer/s hygrometers you use in the incubator? I have one on the egg turner that is a zoo quality one for terrariums and incubators. I have one cheap indoor- outdoor one in as well. Even though both are supposed to be calibrated to + /- 1 degree of actual temp, I am getting five degrees difference between them. (and of course the cheap one on the incubator itself is waaay off!)
