Silkie egg developing black ring at 8 day

[Bantam girls]

Help! I am incubating 4 eggs and everything looked fine until this morning. One of the eggs has developed what appears to be 2 black masses or blood clots on the bottom of the egg. Embryo is still moving on the other side of the egg but I am nervous. This is my first time incubating eggs . I have pictures but don't know how to post them here.
Thank you.

If the embryo is still alive the only thing you can do is leave it alone. It might be ok or it might quit later. Sometimes these things happen.

i get that a lot, and almost threw away perfectly good eggs. Keep the bator shut and make sure that your temperature and humidity is where it is supposed to be. As long as the egg is pointed end down or your turning them properly all should be fine
Are they shipped eggs by any chance

No I got the eggs just a mile away from my house. The lady wasn't even sure they were fertile. The three others look fine. I am turning them by hand. Temp is 100 and humidity is 60%. Can I still candle the egg?
