It appears your candling with the egg in a hoizontal position? How are you incubating the eggs, up right or laying hoizontal?
The reason I ask is because of the position of the blood ring. This is usually the visual you will get from shipped eggs, a blood ring indicates rough handling of the egg. IMO, the air cell is completely detached, and the presence of the ring is a sign of a dead embyro.
How long have they been incubating?
