Okay, I have one regular thermometer which I stick in a ziplock baggie filled with water and folded over to make "water wiggler", it reads 100.9. There is an aquarium thermometer in there also which read 101.2. I have another thermometer which is filled with clay and in a molded egg which reads 98.6. I have a digital thermometer/hydrometer which reads 102 with 46% humidity. I have an outside thermometer which reads 100 on the wall of the incubator. Do I average these temps and say I'm in the good or is there one more dependable than the other? I'm at a loss of what to do. I candled and I have the "spider" in some eggs. I'm on day 5 and the spider is small with few veins. Some I just see the yolk. Thanks for your help.
