What am I looking 4 when I candle??

Well of course I know an embryo, but what will it look like. On day 7 some have red vieny stuff and other look like a round shadow.

The ones with the red veins have a chick growing. I never throw an egg out tho till day 10 which is usually when I candle the first time. If there are no veins by then, there aren't going to be.
