Bought this rcom 20 and because I have and use the Rcom mini (3) successfully, I didn't think I needed to check the temp inside the incubator (display said it was right on) - I've tried to hatch two batches of eggs (first just shipped, but second had some of my own eggs in it). Nothing hatching - lots of blood rings. Decided to check the inside temp and it was only running around 90 -91 degrees. Obviously, not warm enough. Tried to manuallly hike the temperature, but with no difference. Anyone use this incubator, that might have an idea what my issue is. Humidity is staying good.
