Is this a fertile egg?

[Duckmommy5309]

This is my ducks first egg. We wanted to eat it just to taste it, but I took a picture because it looked a little funky. I’m a first timer with incubating and hatching duck eggs, so I don’t know what I’m really doing. I could use some help, I don’t think the egg is fertile but I could use some judging, here is a photo.

I can't really tell from your photo, but what you're looking for is a whitish bulls eye mark on the yolk. You can see one on the egg in the upper right corner.

Thanks for the info!
