on day 10 and this is what I see on EVERY single egg. I'm not sure if I would call this a blood ring but I don't see any other veins. How do I know of they are still alive?

If this is day ten on chicken eggs unfortunately they all quit You may have had a temp spike you were unaware of. This is what a day 10 egg looks like:

Thank you, I thought that and cracked one and it was nothing. I had 11 eggs and on the last one I cracked there was a small Heartbeat. Thanks for the reply!
