Will a Duck Sit on Unfertilized Eggs?

No, a duck will not sit on unfertilized eggs. If there are no ducks around to fertilize the eggs, they will not hatch. The mother duck needs to be with the eggs for them to stay warm and for them to hatch.

If you’ve ever wondered whether a duck will sit on unfertilized eggs, the answer is yes!

Ducks are not particularly picky about what kinds of eggs they will sit on, and will often incubate a mixture of fertilized and unfertilized eggs. This behavior is called “brooding.”

There are a few reasons why ducks might choose to sit on unfertilized eggs. One possibility is that the duck is simply trying to keep all of her eggs warm, in order to maximize the chances that at least some of them will hatch.

Alternatively, the duck may be trying to deceive potential predators into thinking that her nest is full of viable eggs, when in reality it contains nothing but duds.

Of course, if you’re hoping to incubate some ducks of your own, you’ll need to make sure that they have access to fertile eggs! Otherwise, you’ll just be left with a bunch of unhatched shells.

Ducks will typically incubate their eggs for about 28 days before they hatch.

Will a Broody Duck Sit on Unfertilized Eggs?

If you have a broody duck, she will likely sit on any eggs she can find – including unfertilized ones.

While it’s possible to break a duck out of this behavior, it’s often easier (and less stressful for the duck) to simply let her continue sitting.

She won’t be able to hatch any chicks from the unfertilized eggs, but she will probably take good care of them until they eventually go bad.

Does Duck Egg Need to Be Fertilized?

No, duck eggs do not need to be fertilized. Duck eggs will hatch without any intervention from a male duck.

However, if you want your duck eggs to hatch into ducks that can reproduce, then you will need to have a male and female duck mate.

How Many Eggs Will a Duck Lay before Sitting on Them?

How many eggs will a duck lay before sitting on them? This is a difficult question to answer definitively because it can vary so much from one duck to the next.

Some ducks may only lay a handful of eggs before they start sitting on them, while others may lay hundreds or even thousands!

The best way to determine how many eggs your particular duck will lay before sitting on them is to simply keep track of her laying habits over time.

If you notice that she typically starts sitting on her eggs after she lays a certain number, then that’s probably how many she’ll need to lay before she feels comfortable doing so.

When do ducks start laying eggs

Duck Behavior before Eggs Hatch

When a duck is about to lay her eggs, she will start to build a nest out of soft materials like feathers, down, and grass.

She will carefully arrange these materials into a cup-shaped depression in the ground, lining it with down to keep her eggs warm. Once her nest is complete, the duck will start laying her eggs.

During this time, the duck will become very protective of her eggs and nesting area. She may hiss or even attack if she feels that her eggs are threatened in any way.

Once all of her eggs are laid, the duck will settle down on top of them and begin incubating them.

The incubation period for ducks typically lasts around 28 days. During this time, the mother duck will barely leave her nest, only moving enough to turn the eggs so that they don’t get cold.

She will also occasionally drink and eat small amounts of food to sustain herself.

Once the chicks start hatching, the mother duck will help them out of their shells and then lead them to water so that they can learn how to swim.

After that, she will take them back to the safety of their nest where they will spend their first few weeks before venturing out into the world on their own!


No, a duck will not sit on unfertilized eggs. If the eggs are not fertilized, they will not develop into chicks. The female duck will abandon the nest and lay her eggs elsewhere.
