The Mysterious Origins of Black Eggs: Unveiling the Secrets Behind this Unique Phenomenon

Are you intrigued by the rumors of black eggs and wondering if they’re real? While the idea of chickens laying pitch-black eggs is fascinating, it’s actually a myth. This blog post will peel back the layers on this mystery, revealing truths about chicken breeds and exposing some common misconceptions along the way.

Hold on tight; we’re about to crack open a whole new world of egg knowledge!

Key Takeaways

  • Black eggs are a fascinating phenomenon, but they do not occur naturally in chickens. They can be created by coloring regular eggs using dyes or pigments.
  • The Ayam Cemani breed, known for its all-black appearance, is often associated with black eggs. However, their eggs are actually cream-colored and not black.
  • Other chicken breeds like Silkies, Jersey Giants, and Black Australorps have unique black traits but do not lay naturally black eggs.
  • Emu eggs and Cayuga duck eggs also captivate people’s curiosity with their unique dark appearances, while Maran chicken eggs provide a close alternative to true black coloration.

The Myth and Reality of Black Chicken Eggs

Many chicken enthusiasts and breeders get caught in the whirlwind of internet rumors suggesting the existence of chickens laying true black eggs. This captivating concept has ignited widespread fascination, with some chicken keepers devoting their efforts towards breeding such mythical egg-laying hen.

However, the stark reality debunks all such myths – no existing breed lays genuine black eggs. The Ayam Cemani, an Indonesian black chicken renowned for its hyperpigmentation, is often misunderstood to produce black eggs due to its completely dark pigmentation encompassing feathers, beak, skin and even bones.

Nonetheless, it’s vital to clarify that these exotic birds lay cream-colored eggs rather than pitch-black ones as widely speculated on social media platforms and unique food stores.

Misinterpretations have led many into believing this unfounded myth about Ayam Cemani’s mysterious egg color whereas science stands steadfast in declaring there are currently no known genetic instances or cross-breeding feat capable of producing a naturally occurring jet-black eggshell from any poultry species worldwide.

In essence then – the allure of taking a peep inside your nest box only to find glistening obsidian-like ovoids is exciting but remains pure fantasy for now! However intriguing they may appear in manipulated photos or videos online; true-born black chicken eggs remain an elusive dream for backyard homesteaders and commercial poultry farms alike.

Understanding the Ayam Cemani Breed

The Ayam Cemani breed is known for its association with black eggs and unique characteristics.

The association with black eggs

Black eggs often hold a mystical allure, intriguing chicken enthusiasts and breeders worldwide. The Ayam Cemani, an Indonesian black chicken renowned for its unique pigmentation, shows strong association with this peculiarity.

However, contrary to widespread belief, these chickens do not lay black eggs; their eggs are typically cream-colored.

Greenish tinted nearly black emu eggs and the dark hued Cayuga duck’s initial seasonal offerings also contribute significantly to the fascination with these obsidian orbs of life. In certain cases though, misuses of photos on social media have led to false associations between some breeds like Jersey Giant Chicken or Australorp and mysteriously dark eggs.

Unique characteristics

Ayam Cemani chickens boast a unique set of characteristics, setting them apart from other chicken breeds.

  • Their striking black pigmentation covers the entire body, including feathers, beak, comb, and skin.
  • The meat and bones don these same pitch – black hues.
  • This breed produces eggs that contrast with their dark appearance; these eggs appear cream in color.
  • It’s not just their unusual coloration that makes them stand out. Ayam Cemani chickens are also pretty rare.
  • They command high prices for such rarity; most chicks sell for at least $50 each.
  • A gene known as Endothelin 3 (EDN3) dominates their genetic structure. This gene controls skin color, resulting in black pigmentation seen throughout their bodies.

Other Chicken Breeds with Black Traits

Silkies, Jersey Giants, and Black Australorps are some chicken breeds that exhibit black traits.


Silkies, a remarkable chicken breed, flaunt intriguing black pigmentation features – from their fascinating feathers to dark skin. Unlike the Ayam Cemani or Jersey Giant breeds, however, Silkies’ unique coloration doesn’t extend to their eggs.

In fact, these fluffy chicken breeds lay cream-colored eggs that add a charming variety into any egg basket. Known for their friendly disposition and distinctive appearance, Silkies have earned popularity among backyard chicken keepers and poultry enthusiasts worldwide.

Each of these unique breeds – Silkies alongside Ayam Cemani and Jersey Giant – bring individual characteristics to the table in terms of chicken pigmentation patterns.

Jersey Giant

The Jersey Giant is a chicken breed that is associated with the mystery of black eggs. However, unlike some other breeds, the Jersey Giant does not lay black eggs. This breed is known for its large size and calm temperament.

While they have black feathers, their beaks, bones, and combs are not black like some other breeds. Created in the late 19th century in the United States by crossing Black Javas, Black Langshans, and Dark Brahmas, the Jersey Giant is often favored for its impressive size rather than its egg color.

Black Australorp

Black Australorp is a chicken breed that is often associated with other breeds known for their black traits, but it does not naturally lay black eggs. Unlike the Ayam Cemani breed, Black Australorps do not have black beaks, bones, or combs.

They are not connected to the gene endothelin 3 (EDN3), which controls skin color in Ayam Cemani chickens. Black Australorps are known for their excellent egg-laying abilities and friendly temperament.

The Fascination with Black Eggs

Emu eggs, Cayuga Duck eggs, and Maran Chicken eggs are just a few examples of the intriguing black eggs that captivate our curiosity. Discover more about these unique phenomena and their unusual characteristics.

Read on to unravel the secrets behind the fascination with black eggs.

Emu Eggs

Emu eggs are highly sought after for their unique appearance and taste. These eggs are large, almost black in color, and have a greenish tint. They are approximately twice the size of regular chicken eggs.

The black color of emu eggs is due to a chemical reaction with sulfur and iron in the water where they are laid. Because of their rarity and distinct flavor, emu eggs are considered a delicacy and can be sold at high prices.

Many high-end restaurants use them to create unique dishes that leave diners intrigued by their exotic nature.

Cayuga Duck Eggs

Cayuga Duck eggs are quite unique in appearance. They start off as black but gradually turn white at the beginning of the season. These eggs are larger than other duck eggs, making them visually striking and captivating to many people.

The contrast between the initial black color and the eventual white shade adds to their allure and makes them stand out among other types of eggs. However, it is important to note that unusual colors inside eggs, including black, can indicate bacterial or fungal contamination.

So it’s always crucial to ensure proper cleanliness and safety when handling Cayuga Duck eggs or any other type of egg for consumption.

Maran Chicken Eggs

Maran chicken eggs are highly sought after due to their association with the fascination surrounding black eggs. This unique breed of chicken lays dark chocolate-colored eggs, which can be a close alternative to true black eggs.

The distinctive color adds an intriguing and visually appealing element to culinary creations and has made Maran chicken eggs popular among chefs and food enthusiasts alike.

Unusual Phenomena of Black Eggs

Black eggs have sparked curiosity due to their unusual color, and there are two main reasons behind this phenomenon – genetics and the egg coloring process.

Genetic reasons

The black pigmentation in Ayam Cemani chickens is determined by a specific gene called endothelin 3 (EDN3). This genetic factor is responsible for the unique dark coloring of their skin, feathers, beak, comb, and bones.

However, it’s important to note that other black chicken breeds like the Jersey Giant and Australorp do not have the same genetic factors for black pigmentation as Ayam Cemani chickens.

The Silkie chicken breed also has some black features but lacks the genetic factors that result in black eggs. So while genetics play a significant role in determining the coloration of eggs, different breeds have distinct genetic reasons behind their characteristic traits.

Egg coloring process

Chicken eggs can be colored black through a process involving the application of a black dye or pigment to the eggshell. This is not a natural occurrence and requires intentional coloring by breeders.

The Ayam Cemani chicken breed, known for its black pigmentation, lays cream-colored eggs that are then transformed into black eggs through this coloring process. The genetics behind the black pigmentation in Ayam Cemani chickens involve a gene called endothelin 3 (EDN3) that controls skin color.

Breeders have dedicated their time to breeding chickens that lay black eggs by using dyes or pigments, resulting in these unique and eye-catching dark-colored eggs.

Controversies Surrounding Black Eggs

Some controversies surrounding black eggs include the misuse of photos and videos to exaggerate their appearance, as well as manipulation of egg color through artificial means.

Misuse of photos and videos

Some individuals have been misusing photos and videos to create false perceptions about black chicken eggs. They may use filters, editing techniques, or even dye regular eggs to make them appear black.

It is important to be cautious when encountering these images online or in social media, as they can be misleading and contribute to misunderstandings about the reality of black eggs.

Manipulation of egg color

Chicken egg color can be manipulated through a process that involves genetics and a specific gene called endothelin 3 (EDN3), which controls skin color. This manipulation is typically done with the Ayam Cemani chicken breed, known for its black pigmentation.

However, it’s important to note that the eggs of Ayam Cemani chickens are actually cream in color, not black. Other chicken breeds like Jersey Giants and Australorps do not have naturally black eggs and cannot be used for manipulating egg color.

Do any melanistic chicken breeds lay true black eggs?

Melanistic chicken breeds, such as the Ayam Cemani, are often associated with laying true black eggs. These unique chickens have a high concentration of pigment called melanin, which gives them their distinct black appearance.

However, it’s important to note that despite their dark plumage and internal organs, the eggs laid by these chickens are not completely black in color. Instead, they tend to be shades of brown or have a darker tint compared to regular chicken eggs.

So while melanistic chicken breeds may not lay true black eggs, they still produce fascinating and visually striking variations from the typical egg color spectrum.

What is the significance of Ayam Cemani chickens in the culinary world?

Ayam Cemani chickens hold great significance in the culinary world. Their unique black meat and bones make them a sought-after delicacy in high-end restaurants. These chickens are known for their all-black appearance, with black feathers, beak, comb, and skin.

However, it’s important to note that Ayam Cemani chickens do not lay black eggs like some other black chicken breeds. The rarity and distinctive features of these chickens contribute to their high price on the market, with most chicks selling for at least $50.


Discovering the secrets behind the mysterious origins of black eggs has unraveled an intriguing phenomenon. While black chicken eggs are highly sought after, they are not naturally occurring and can only be obtained by coloring regular eggs.

The Ayam Cemani breed, with its all-black pigmentation and rare genetics, continues to fascinate chicken enthusiasts and remains a delicacy for high-end restaurants. Unveiling the truth behind these unique black eggs adds another layer of fascination to the world of poultry breeding and egg production.


1. What are black eggs and where do they originate from?

Black eggs are a unique egg variety characterized by their dark shell color. Select chicken breeds like the Black Copper Maran produce them, and in places like Owakudani, Japan, they create them by soaking regular eggs in hot spring waters.

2. Does the color of an eggshell affect its nutritional contents?

The color of an eggshell does not influence its nutritional content; this depends more on the chicken’s diet. Whether it’s cream-colored or dark chocolate colored eggs, nutrients remain consistent.

3. Can I breed chickens that lay black eggs in my backyard?

Chicken breeders focus on genetics to develop different varieties, including those with blackish or green tinted shells. Chicken-keeping could involve various birds for these purposes – breeds like Svarthona and Vietnamese Black H’Mong known for darker shells may be ideal.

4. Why is there a difference in appearance between the regular chicken and ones laying dark-colored eggs?

Certain chicken varieties have melanoblasts leading to fibromelanosis which gives them distinct appearances such as black skin, comb and bone; even resulting in darker feathers giving often fascinating results like a black sheen.

5.What influences the change of seasonal egg colors?

Different factors might lead to subtle changes of seasonal egg colors including hen’s age & diet; though generically an ‘Easter Egger’ would consistently lay green tinted or cream colored eggs throughout all seasons based upon genetic attributes.

6.Can one eat a boiled Egg soaked overnight from Owakudani’s hot spring water appearing jet-black (Kuro tamago)?

Absolutely! In fact these Kuro Tamagos gain iron sulfide engulfment after being cooked within volcanic hot springs making their shell turn jet-black while enrichingtaste although retaining usual characteristics inside akin to any other hard-boiled variations.
