Aw, gotta love those broodies! I was searching BYC to jog my memory about how the hygro in the Genesis ran, high or low, and found that I did incubate a few eggs in it from the Brahmas in March 2018. I completely forgot doing that, but I said that the time that in comparison to my calibrated analog hygrometer, it reads a tad low. I can't find my little hygro anywhere, so I ordered a new one to keep the Genesis honest. I'll figure it runs about 5% low and adjust accordingly until that gets here and I calibrate it. I didn't get any eggs from the Rocks in time to put any in the incubator. Jane and Athena laid eggs in the same nest late yesterday, but even if I knew which was which, it was too far behind, IMO.
ETA: Nah, I canceled the order for a new hygro. Seemed overkill. I'll just assume that the Genesis is running about 5% too low and adjust accordingly. I found another older hygro/thermo combination unit, popped in a new battery and I'm calibrating it today. Maybe it will be a good backup, hopefully not as off as the Fluker was.
