Blood Ring?

[and1223]

This is my first time incubating Buff Orphington eggs and two dark brown eggs Half BO and Black Copper Maran.
I’m on day 14. The two dark brown eggs look little one had a blood ring and the 2nd looks infertile. I need confirmation though. I’m using a Hovabator 2370 with a fan and automatic turner. Should I remove these two eggs immediately to prevent exploding? Any help is appreciated

It is very hard to tell what I am seeing from the photos.

I do not see blood rings and I swear I see veins in two of them. The last one looks dead though.

I would keep them in longer unless they smell like sulphur.

How did they do?
