On my Little Giant /fan testing without eggs, I could get 99.5 degrees on 2 different thermometers. One laying on the wire screen, one reading on the therm. on its stand that came with the bator. Finally found a digital therm. and humidity thingie at Walmart. It's reading 95 and the original is at 99.5. They are both at the same level, either side of the bator. I put my guinea eggs in this morning at 5am. Which thermometer should I go with? Should I split the difference? Help please!
