I candled my eggs, again, tonight in a darker room. On several eggs, again, I see a red ring on part of the egg, but the eggs are the only ones that really look like there is a chick moving around in there. So far, nothing smells. I cant see vascular lines on anything else. However, only 3 eggs look completely clear, which tells me that something is happening in the others. What does a blood ring look like, and what causes it? I tried a search, and nothing is coming up.
