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.
The answer is "gums".
Hens can live a whole life without fertilization and still lay fresh eggs just as frequently as hens who are mated regularly. To produce fertilized eggs for hatching, hens must be mated about once weekly.
The difference is simply the animal inside. Hen eggs produce chickens if they are fertilized, and starfish eggs produce starfish. Also, starfish eggs do not have a hard shell - they are somewhat gelatinous.
"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 it has eggs in the nest.
If a duck is broody, it will lay on a 'nest' and make peculiar growling sounds when anyoneapproaches and she may become fairly aggressive.
They eggs will be fertilized about a week after the rooster consistantly starts to mount the female.
a hen can still lay fertilized eggs up to 30 days after contact with a rooster
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.
To get things straight, ducks aren't nocturnal so NO they don't leave their nests at night. 1) The mallard duck is a single hen (mother duck). Single mothers are the most common in mallard duck families in which the mother duck stays in her nest for hours to secure her eggs. She does leave but only for 3 minutes to grab herself some food and then rushing back to her nest. 2) The mallard duck is a hen whose mate the drake (father duck) will feed her so that she does not have to leave the nest while the eggs have yet to hatch. In these rare families containing both parents, the drake will feed her until the ducklings emerge. However, if the mother decides that she needs to go feed herself instead of heavily relying on the drake then she will leave the nest for temporary like the single hen without the drake. If you're wondering about the eggs, the drake will secure them during her absence.
