Oh, and often times in the beginning, a very large blood vessel developing, can be mistaken as a blood ring because it is stretching out about half way around the egg. Best wait for other tell tell signs of it being a bad egg. No air sac by day 8..or movement is a good sign. Well, bad sign.![]()
I agree with this whole heartily. There is a stage where normal development appears very much like a blood ring. Especially to those unfamiliar with candling and hatching. I made that mistake my first round of chicks. Cracked a healthy developing egg
