Well, I am at day 4, decided to do a first candling. Many of the eggs look porous, and many just have a black mass floating around in there. Some, though, had some veins and an embryo started. From what I could tell, I have about 25% with veins and embryo. I may of missed some of them, because it took a while to find the first vein, and they were small. I will try again later, maybe a week or so.
