I have a quick question about the r-com 50 incubator. I am egg sitting/hatching for a friend who is on vacation. Lock down is today and I can't remember if I am supposed to take the egg tray out before putting in the egg cartons with the eggs fat end up. My friend wants them to hatch in the cut down egg cartons not laying down on the egg tray. I took the tray out but now there is a gap on the edge caused by the movement of the turner mat. I let it go one more rotation and now the gap is on the other side. Does anyone have this incubator and can answer this question for me? TIA!
