Unveiling the Truth for Do Ducks Eat Their Own Eggs?

Updated: 03 Mar 2024


In exploring the curious behavior of ducks and their relationship with their eggs, one can’t help but wonder why these unique creatures might turn to eating their own offspring’s potential homes. The question of “Do Ducks Eat Their Own Eggs” surfaces frequently among poultry enthusiasts and is worth a deeper dive.

While it’s generally no, ducks do not eat the viable, fertilized eggs that they lay, certain conditions encourage this uncommon habit. Factors such as an unbalanced diet, overcrowding, curiosity, hunger, and boredom can lead to ducks eating their eggs.

Most cases occur when an egg is broken by accident, tempting the duck with the unexpected taste of its contents. This can develop into a dangerous habit, potentially introducing deadly diseases to the flock.

From my personal experience, ensuring that your ducks have a well-balanced diet rich in calcium and protein can significantly prevent this behavior.

Overcrowding should be avoided to reduce stress and accidents that might lead to eggs being broken. It’s fascinating yet impossible to stop this behavior entirely without addressing the underlying reasons.

As we are discussing in this article, the key to preventing ducks from eating their eggs lies in understanding their unique, interesting behaviors.

Delaying in addressing the issue only makes it harder to stop. Therefore, being proactive in providing an enriched environment and proper nutrition is crucial for keeping your feathered friends healthy and preventing them from developing the habit of eating their eggs.

Do Ducks Eat Their Own Eggs?

In my years of tending to ducks and observing their behavior closely, I’ve noted an intriguing habit that often perplexes many: ducks do, indeed, sometimes eat their own eggs.

This behavior isn’t born out of a bizarre preference but is a common problem rooted in nutritional deficiencies, particularly a lack of calcium and protein in their bodies.

It’s a scenario not unlike what chickens face. When ducks develop this egg-eating habit, it’s a clear indication that their diet is lacking. They seek to replenish the missing nutrients through the most direct source available to them—their eggs.

Ducks eating their eggs in diet

Recognizing this, I’ve learned to feed my flock a supplemental diet rich in proteins and calcium. This proactive approach has made a significant difference.

Whenever I notice that a duck has started this behavior, I immediately adjust their diet to curb the issue. This personal journey has underscored the importance of closely monitoring and catering to the dietary needs of my feathered charges.

Why are Eggs So Important to Ducks?

Understanding the pivotal role eggs play in the life of ducks unveils a realm of evolved behaviors and adaptations that are nothing short of fascinating.

At the heart of this intricate dance between nature and nurture lies the egg, a precious commodity teeming with nutrition essential for developing ducklings. Each egg is packed with protein, fats, vitamins, and minerals, making it an ideal food source for growing healthy baby ducks.

The nutritious yolk and essential fat, alongside the protein-rich whites, are crucial for muscle development, while the calcium-rich shell lends itself to bone strength and beak hardness.

Ducks have even adapted to reabsorb leftover calcium from the shell after hatching, a strategy that ensures they make the most of every resource available for their future offspring and the continuation of their genetic lineage.

This deep-seated value of eggs to ducks—beyond mere nutrition—touches on their essential motivation to incubate and protect their potential progeny, ensuring the species’ survival.

Female ducks, driven by hormonal responses and natural instincts, are hard-wired to lay, care for, and nurture their eggs, a process deeply imprinted in their biology.

These instincts override the impulse to consume the eggs as a food source, illustrating a profound balance between the need to nurture and the necessity to consume.

Such behaviors highlight the ducks’ capacity to prioritize laying and brooding over immediate nutritional gain, ensuring not just the survival of their immediate offspring but the long-term viability of their bloodline.

Through this lens, we see how the life cycle of a duck, potentially spanning up to 10 years, is a testament to the intricate adaptations and behaviors that have evolved to support not only the individual but the species as a whole.

Do Mother Ducks Eat Their Eggs?

In the intricate world of avian behavior, mother ducks, or mama ducks, as they are affectionately known, exhibit extremely strong urges to nurture their offspring from egg to adulthood.

This journey begins with mating and laying, transitioning swiftly into full broodiness mode, where the mama duck becomes a heated, protected fortress for her nest.

Despite the occasional quick breaks to nourish herself, she meticulously plucks her feathers to line the nest with soft down, ensuring a cozy incubation environment.

This act not only keeps the eggs warm but also serves as a camouflage against predators. To further safeguard her future offspring, she may puff up and spread her wings to appear larger and more threatening, showcasing strong attachments to her brood and a willingness to defend them fiercely.

Even during short breaks, her strategies to lead predators away through distraction displays underline her dedication to their survival.

However, when it comes to the question, “Do mother ducks eat their own eggs?” it’s crucial to understand the context. While their default instinct is not to snack on their eggs, there are exceptions.

A mama duck may abandon or consume non-viable eggs, a pragmatic decision driven more by the nutritional incentive and the need to maintain a clean nest rather than a lack of maternal drive.

This act allows her to reclaim some of the energy invested in laying them. Once the adorable ducklings hatch, her role shifts from protector of eggs to guardian of the young, protecting and guiding them on their journey to the water.

This transition from egg care to duckling care is a testament to the mama duck’s adaptive strategies, ensuring the continuation of her future offspring while balancing the nutritional needs and fertilized eggs’ safety.

Her life revolves around this cycle of laying, nurturing, and ultimately leading her offspring towards independence, a beautiful illustration of nature’s balance between nurturing and survival.

Will Ducks Eat Their Own Eggs?

While it’s unlikely that ducks will eat their own eggs, certain triggers can lead to this behavior. An accidentally broken egg may introduce them to the taste, and if it feels good, they might start an eating habit.

This could develop from an unbalanced diet, boredom, hunger, or overcrowding in their living space. A notable cause is calcium deficiency, for which eggshells serve as a great source of calcium.

Considering eggs are packed with protein, an essential nutrient for growth and overall health, it’s crucial to pay attention to the protein requirements at each life stage of the duck.

Rotten eggs or those that fail to hatch over a long time become less enjoyable for the flock, potentially leading to a whole raft of issues.

Preventing this acquiring behavior is key; ensuring a supplemental diet rich in calcium and raw taste experiences can stop egg eating and prevent future occurrences.

Do Pekin Ducks Eat Own Eggs?

Pekin ducks, a popular domestic duck breed known for their tasty meat and large white eggs, prompt curiosity regarding whether they share habits with wild ducks concerning their eggs.

While they possess natural instincts to incubate and hatch viable eggs, there are caveats. These ducks might consume non-viable or damaged eggs within their nest.

Given their tendency to lay a large number of excess eggs, not all can be incubated, especially if unfertilized.

This leads to a scenario where domesticated ducks might intentionally consume eggs, not for their potential to hatch ducklings but as a source of nutrition, driven by their hormonal drive for offspring care but overridden by the practicality of not wasting nutritious eggs.

Such maternal behaviors adapt based on the inclination to ensure the survival and health of their offspring and themselves.

When Might a Duck Eat Its Eggs?

Ducks, in general, won’t purposefully eat their viable eggs. However, exceptions occur when eggs become cracked or damaged in the nest, as ducks might consume them to prevent predators from being attracted by the scent.

Non-viable eggs, with their refined sense of smell, ducks can detect and decide to eliminate those that might rot, explode, and attract predators or make the flock sick.

Furthermore, ducks may snack on eggs that cannot be properly incubated within clutches that are too large for their body heat to cover, proving impossible to manage.

Excess or unfertilized eggs, especially in the absence of a drake to fertilize the hens’ eggs, lead to a surplus that won’t hatch into ducklings, offering a free opportunity to regain lost protein and calcium.

Why Ducks Eat Eggs?

Ducks are omnivores that love to eat plants, insects, and crab-like items. But eating eggs was not common in ducks. Potential reasons for ducks to eat their eggs are as follows.

Unbalanced Diet:

A main reason ducks indulge in eating their eggs is an unbalanced diet. During egg-laying, ducks require healthy food sources high in calcium—at least 3% of their diet—to sustain their calcium intake for eggshell production.

When duck food doesn’t provide enough calcium, a common scenario also seen in chickens, ducks may turn to pecking at eggshells to supplement their diet. This lack of protein and calcium leads them to eventually consume the content of their eggs, underlining the importance of a balanced diet.


Overcrowding in the duck shed creates numerous problems, including a major cause for egg-eating. In overcrowded situations, ducks don’t have enough space to remain separate, leading to eggs being more likely to break or crack easily. The shells of these eggs become easy targets for consumption, emphasizing the need for adequate living conditions.


In some cases, ducks, already curious by nature, may break their own egg to taste what’s inside and, finding it palatable, continue this behavior. Curiosity drives them to explore and, sometimes, develop unexpected habits like egg consumption.


Hunger is a straightforward cause. Without enough food and water, ducks become thirsty and hungry, leading them to look for food anywhere they can, including cracking open eggs. Ensuring ducks have constant access to nourishment can prevent this behavior.


Lastly, boredom in a small space with nothing to do can lead ducks to bully each other or start cracking eggs. This behavior is a sign of environmental and mental stress, indicating the need for more engaging habitats to encourage healthier behaviors among the flock.

How to Prevent Ducks from Eating Their Own Eggs:

When ducks start eating their eggs it is necessary to take some step for its presentation.  Some of these steps are as follow.

Feed Your Ducks with Balanced Diet:

To combat the lack of calcium and proteins that often leads ducks to eat their own eggs, it’s crucial to ensure they’re getting a balanced everyday diet.

Providing high-quality poultry food designed for egg-laying ducks ensures they receive the necessary nutrients.

Integrating crushed oyster shells into their feed is a perfect way to add more calcium to their food, addressing nutritional deficiencies that trigger this behavior.

Give Them Enough Space:

Boredom and overcrowding are among the leading causes of egg-eating. This issue can be quickly solved by ensuring ducks have enough space and room to roam, which helps prevent them from getting bored and bullying or cracking eggs out of frustration. Regularly collecting eggs twice a day also helps to prevent the egg cracking temptation, reducing the chances of ducks developing a taste for their eggs.

Remove Broken Eggs Quickly:

Cleaning out broken eggs from nest boxes is an effective method to prevent ducks from eating them. Keep in mind that even a single shell from a fresh egg can introduce the taste of raw eggs to ducks, enticing them to eat more. Prompt removal of broken eggs minimizes this risk.

Remove the Egg Eating Ducks:

If egg eating starts with one duck, it often encourages others to join in. Keep an eye on your poultry to spot any duck that starts eating eggs and remove it from the group to diminish its influence on the rest of the flock.

Don’t Feed Them with Cracked, Raw Eggs:

An efficient way to prevent ducks from developing an egg eating habit is to avoid feeding them cracked or raw eggs. If providing eggshells for calcium, rinse them in clean water, dry them in the oven, and ensure they don’t get the taste of raw eggs, which could encourage the unwanted behavior.


While ducks may sometimes eat their own eggs, this behavior is typically driven by underlying issues such as nutritional deficiencies, lack of space, boredom, or the presence of broken eggs in their environment.

Addressing these root causes through a balanced diet rich in calcium and proteins, providing ample space to reduce stress and overcrowding, removing broken eggs promptly, and separating habitual egg eaters from the flock can significantly mitigate this behavior.
