Yep, I was in the first one, and my Hygrometer is calibrated. I was originally using a Little Giant with a Calibrated theremomiter/hygrometer. I didn't like that incubator, so I borrowed a NR360 from a friend, became they seemed to be out of stock. The friend that hatched with it got a pretty good hatch rate while trusting he gauge, and everyone else on here said its pretty trustworthy.
I would use a calibrated thermometer, but I calibrated it twice doing the same thing each time, and got different results by 2 degrees each time. I didn't trust the calibration, so I decided to go with trusting the gauge.
I dont get it though, all the eggs were alive a day ago, and in a day over half have quit? It doesn't make sense. I didn't do anything different, I don't get it.
