We are trying to hatch using a Little Giant with fan and turner and have already lost one setting of eggs because of inconsistent temperatures. I can't find a dependable thermometer. I have tried bulb type and digital type. How do I approach this problem? Is there a 100% reliable therrmometer out there? Can't get the humidity over 34% either. I have all of the water cavities filled + I added 4 little cups to hold extra water. Still no luck. Is it me or the machine?
