THis is my third time incubating but this time I don't have an auto egg turner. I have 15 eggs in an LG styrofoam bator witha fan. I am super annoyed by the fact that when I turn the eggs, they frequently roll to what might be the same spot. I am worried they will end up spending too much time on certain sides. Could I use an egg carton to hold the eggs (pointy end down) and rotate it in the cartons ? Or would I be better off just rolling them on the mesh and hope fo the best?
