I'm behind, seeing that I have answered a question that was already answered, but oh well..will do this one too just in case.
I, personally, hand turn my eggs three times a day. I put an X on one side..and a 0 on the other, alternating from side to side..3 times a day.
I have mine on their side, some people like egg cartons. See the X? When time to turn, I slowly turn them to the 0. :)
