Blood ring in egg?

[Jinglebells0518]

I have an egg in the incubator that Never developed but I left it just in case. It's sibling of the same age is pretty far along. So today is day 13 and I decided it was definitely rime to call it quits on the dud. So I candle to make sure I'm removing the correct egg and there is a ring of red. About the size of a dime. It doesn't go around the whole edge of the egg but is kind of just floating at the top. Looks similar to the attached picture I stole from online. I just want to be sure this is a blood ring before I trash the egg because it doesn't look like most pictures I've seen but it also doesnt seem possible to be a developing embryo on day 13.

What causes blood rings to form? This was from an egg that never developed at all and that I thought was unfertilized.

That would be an early quitter. It was fertile, but something happened and it didnt develop far enough to get A blood ring on the shell.

Weird. I checked it at day 7 and there was nothing!

ive had eggs do that before and on opening there is a circle of blood around the yolk, no veins, and no embryo.

It takes time for the small veins that were there to disolve and then for the blood to pool together. I'd say somewhere day 1 - 3 is where it would have quit.
