Duck Egg status - 9 days old

[aude]

Hi, I have been incubating this egg for 9 days. I have no idea if it is even fertile. I can't really see any blood vessels...one side looks darker and the other looks empty. These aren't the best pics, but please let me know what you think. Side "z" looks clear and empty. There is something I thought might be blood ring at bottom of side W?

Doesn't look fertile to me. By now you would already see veins and a small embryo starting to form. The dark part that you are seeing is just the yolk.

I agree, it’s infertile.

Should look something like this at day 9
