It's not likely to hurt them, anyhow. The 'don't turn the eggs' thing has been shown to be a myth, when tested. Once they get well into incubation, they tend to lose some water, and then they won't roll (though this doesn't always happen, lol).
I remember a thread on here where one guy turned his eggs everyday just to test the myth and he hatched out babies just fine but with this being my first clutch I want to get everything right. Thanks everyone
