What does a blood ring look like?

[theron]

I have a dozen chicken eggs in the bator which are going to hatch about two days after easter. all of them have veins and a dark spot which is the chick, but one egg has like a red ring around it. I can't get any pictures, but i think it is a blood ring which means the chick died right? I would like to see any pictures you guys might have so i can compare it to. Thanks

ya that's a blood ring, quite literally it looks like a redish ring around the egg. This is the best pic that I got it day 8ish
you can see the ring
