A duck will sometimes sit on unfertilized eggs. Usually, after a while the duck will come to realize that the eggs are not going to hatch and she will give up and move on.

You can't fertilize an egg once it is out of the hen.In order to have fertilized eggs, you must keep a hen with a rooster, then collect the eggs to incubate them and hatch chicks.
They sit in the hen house on eggs, on the roost or in a nest.
Eggs are fertilized inside the hen by the rooster. Hens will lay eggs whether they are fertilized or not.
Only if they have mated with a rooster. Even if a rooster in in a flock though, her eggs may not be fertilized, as he may not have mated with her. In that case, if you really want the hen to lay fertilized eggs, you could consider penning the rooster and hen up together for a few days.Actually, you can eat the fertilized eggs. It really makes no difference.The answer to your question is that yes, hens lay fertilized eggs, but only if she has mated with a rooster. If she hasn't, the egg isn't fertilized.
A week after your duck lays her eggs, you can take them in the dark and quickly flash them with a flashlight. If they are alive then you will see a dark area inside an otherwise clear egg. "At about seven days after setting, candle the eggs and remove any eggs that are infertile (clear) or have dead germ (cloudy)"(Duckhealth.com).

"Nest eggs" Used to induce new pullets to lay their eggs in specific places. Often substituted for fertilized eggs under a broody hen so the real eggs can be artificially incubated without causing the brood hen to stop brooding. Golf balls and rocks have been used for this purpose also.

If a duck is broody, it will lay on a 'nest' and make peculiar growling sounds when anyoneapproaches and she may become fairly aggressive.
A fertilized egg that is growing into a chick, after the hen has laid the egg, requires a warm and dry environment for a few weeks to incubate. Man-made incubators are built to incubate over 200 eggs at a time (bigger incubators can hold more), or a nest of straw, grasses and feathers built by a hen are also sufficient, provided the hen is sitting on her eggs as much as she can.
It can be,sometimes you will see blood patches in fertilized eggs.
Once hens are of a certain age, they will produce eggs. If you want an unfertilized egg, don't put the hen with a rooster. Depending on the breed, she will give you 1-6 eggs per week. If you don't have a nest box for her, she will make a nest on the ground. If you want fertilized eggs, place a rooster with the hen, make sure the rooster knows his job, and the next day you may have a fertilized egg. There is a way to tell if the egg has been fertilized once it's cracked open, but through the shell, you can't tell until the egg is incubated and the chick starts to develop.
The hen will continue to lay fertilized eggs for up to 10 days after the last mating.
