Most of the egg turners that come with incubators have the egg standing on end as they would be in an egg carton, and they are then tilted slowly side to side. The commercial hatcheries turn eggs in this fashion also. Many folks who don't have an electric turner place their eggs in a carton, and tilt the whole carton. I've done so. (I've also incubated them laying flat on their side, and rolled side to side.) When I incubate, I make sure that my eggs not only get turned, but get moved around in the incubator. My bator, even with a fan, and lots of air baffles to help eliminate hot/cold spots... still has some temp variance. So, the eggs get moved around between warm/not so warm areas. Yes, a broody will roll her eggs. Goes to show, there's no one right way to do it. The end justifies the means.
