I have the Hova Bator 1602N, I have 36 eggs in it, as of last night, 2 thermometers, one says 97, (its got a probe that I can move around, so I placed it beside the other one )the other says 100...question....do I rotate the outside eggs into the center to keep the temps equal throughout? I read this somewhere when you don't have a fan installed in the bator. I hatched out 5 last week, from 12 eggs....was hoping for better results this time...advice?
