Blood Ring? Advice?

[ChickFanatic8]

Hi all,
I have read that when you find a blood ring in a candled egg, you should remove the egg so that it doesn't explode and spread bacteria to the other eggs. however, I also saw a video that advised never to remove the egg, in case it actually works out... I'm not sure what to do. I think it is safe to assume that the egg is no longer alive (see photo). Should I dispose of it? If so, how? Please offer advice! And excuse my grainy photos and any ignorance on my part, I've never incubated eggs before and I'm using a phone camera. Thanks!!

If you find a blood ring, then yes, you should remove it. An egg with a true blood ring will never develop into a viable embryo, and it could rot and explode.

However, I'm not sure from this picture if your egg actually has a blood ring. What day is this egg on? When you're looking at the egg in person, can you see veining? Does the embryo in the middle there move at all? Or was there veining before that has now disintegrated?

That doesn’t look like a blood ring to me. They’re typically around the perimeter of the egg horizontally below the air cell.

That looks like the developing vascular system around an embryo.

Agree with the above.

In the blood rings that I've seen, the ring is clearly defined. Even if I have what I think is the beginning of a blood ring, I give the egg 24 hours, candle it again and carefully look to see if the blood ring has become more defined, if the embryo looks like it has developed, if there was vascularization and has it has broken down.

If the answer is yes, I pull the egg. If I am still uncertain, another 24 hours, and check again.

So far I've never had one go longer than 48 hours without me being certain that it was a blood ring and failure to develop.

When in doubt, leave it in the incubator. Candle again in another week. If the egg still looks like that, then pull.
