A little sad today. I candled my store bought fertile eggs today and not one has veins that I can see. I put them under my hen on Friday. Shouldn't I see something? One looks like the yolk is broken and there is a blood ring? a red circle on it that moves around. I put them all back under her after candling. Just not sure what to do now. Do I let them sit another week? Do I candle in a few more days? Do I beg again for fertile eggs? What to do? What to do?
