Hey all. I set 20 eggs in my RCOM 20 PRO yesterday. I have mixed various breeds of eggs in the incubator. It was so easy to use. Just filled it up with watrer. Selected the pre set "Chicken Function" and hit enter. Thats all I needed to do. I turned it on an hour prior to putting in the eggs. There was no need to calibrate temp or humidity, it was spot on within half an hour. I had a couple of glimpses of the temp and humidity and it has remained spot on. Fingers crossed. Anyone care to join me ??
