Keep all the eggs in the bator even if you're not sure if they're going to hatch out? this is my first hatch and I'm not really sure when I candle. And I've read that I shouldn't candle after day 16. Some look like nothing's in there - kinda blurry and others - well I've got dark marans that I can't tell and there seems to be some EEs that might hatch. None of them smell bad so I'm wondering if it's okay.
