Do chicks hatch better in the dark?

Im curious if chicks will hatch better in the dark or in the light.

I don't think it matters at all.

I cover my incubator up just as long you don't cover that error holes for the humidity. I kind of see it as the eggs under a broody hand and it's usually dark so that's what I do.
