I am new at this so probably doing it wrong .

We were all new at one time.. no worries. We're here to help if we can.

If you are positive that you have only female ducks, then the egg is most definitely not fertile. Eggs can appear to have a bullseye sometimes and still not be fertile. But it is impossible for gender to change, or for 2 females to produce fertile eggs.

One way to check fertility for sure - incubate the egg for a week and see if anything develops.

K thank yall so much. Had posted some where else also and they said it was fertilized so was wondering what people here would think.

Where I live we often have fertilized eggs in our supermarket eggs. Breeding them even let to a result of near 20 procent being fertile and resulting in chicks!

The problem;
Just like people, chicken/ducks/anything else come in great varieties. Sometimes a male chicken looks 100% like a female chicken, even by proffesional sexers. but in fact, has male genitalia. Often smaller then usual... but let that one run around in an free-range chicken coop, which in my country means a reaaaally big room with 5000+ female chickens....and voila; someone is in rooster-heaven with 4999 virgins and we end up with a lot of fertilized eggs ;') And since the chicken-farmers has a whole hall of 5000 female chicken that all look like female chicken; good luck finding the lucky man
And with 5000+ he isn't probably the only man in disguise...

You could test this. But is would involve quite some work. Rotating them, checking their eggs, keeping some locked up for a time, and I don't know how long the breedings season lasts where you live.

And is it worth it. What if one is a man in disguise. It has 3 females. And if you keep eating the eggs nothing is going to happen.
