So I have a little Giant incubator with the fan. The front digital portion of the incubator is reading 45-50% humidity. I bought a separate hygrometer/thermometer which I calibrated using the salt water test. It was off 4 degrees from the 75% correct humidity. I dropped it in the incubator and it was reading 30-31 % humidity without the 4 degrees taken off. So it was reading 26% humidity. I'm wondering if all my eggs have gone bad now if the humidity was wrong from day1. I also thought the incubator would hold 40-45 % humidity without any water.
