What day did this embryo pass?

This egg was on day 12 and was clearly dead. I decided to open it up to see if there were any clear deformities. What day do you think it developed to? Day 8?

Probably day 7 - 10, it is hard to pinpoint the exact day, but it is before day ten as the embryo does not have feather tracts yet.

Ohnoo I’m so sorry! I agree 7-10 days around. I’m currently hatching baby chicks and they grow fast! good luck with the others though
