When do you make a verdict on dark eggs? I am on Day 7 and to be honest on either side of the egg I can't see any veins in the eggs. I can't even see the air cell from the smaller side but I can see it if I shine the light on the fat end. I don't flip the eggs I just shine it from the top down. I can't see anything else besides that. I only had 4 non-starters from my other lighter eggs of 41 (as far as I can tell).
