Hi everyone. I'm a little upset right now. our eggs are on about day 30. When they first were laid, they candled fine. Strong veins. Now, many of them in the tub are moldy, and we can't get them to candle properly. It's almost as if the skin of the egg is too thick for the light to penetrate. I'm so worried. Has anyone dealt with this, and what can we do to save them? Thanks!!!
