Well, today is 1/3 of the way through the set. I thought I'd try to candle the eggs, as suggested, but the brightest LED flashlight I have doesn't even BEGIN to shine through the lightest colored egg of the hatch. So, do I just leave them alone and hope they are okay? If any of them start to rot, am I going to smell it when I remove the incubator top to fill the water reservoir? This is my first time - I don't have any experience at this...
