Duck egg candling help

[00talyssa]

Does anyone know if this egg is fertilized!? I have another egg that is definitely fertilized and around the 10 day mark. Idk if this egg is in the early fertilization stage or if there was an early death or if it’s fertilized at all?
Thanks!

Looks fertile, but I also see a blood ring. Likely an early death.
