What Color Are Chicken Eggs

Key Takeaway:

  • Chicken eggs can come in different colors, including white, brown, blue, and green. The color of the egg is determined by the breed of chicken and the color pigments in their diet.
  • White eggs have a white eggshell color and are often associated with having a high-quality eggshell. Brown eggs, on the other hand, have a brown eggshell color and tend to have a thicker eggshell. Blue and green eggs have different variations of blue and green eggshell colors and are often associated with certain chicken breeds, such as Ameraucanas and Leghorns.
  • The color of chicken eggs can also be affected by various factors, including genetics, diet, and age. Different chicken breeds will produce different egg colors, and their diet can also affect the color of their eggs. Additionally, as chickens age, their egg production may decrease, and the color of their eggs may also change.

Learn about egg colors like brown, white, blue, and green. Start with the solution of chicken egg color! Let’s focus on chicken breeds and their eggshell colors. We’ll look at white eggs, brown eggs, blue eggs, and green eggs. We’ll give a brief overview of eggshell color, quality, thickness, and factors that influence the egg color genetics and pigments.

White eggs

One key factor affecting white eggshell color is genetics. Chickens with recessive genes for lighter pigmentation tend to produce more white-shelled eggs compared to those with darker pigmentation. However, it’s important to note that while genetics play a significant role, other factors such as diet and age also affect both the overall quality and color of an eggshell.

It’s worth noting that white eggs may not necessarily indicate inferior quality or nutritional value compared to other colored eggs. The difference mainly lies in visual appearance rather than nutritional composition or taste. In fact, white eggs are often preferred for their clean aesthetic appeal in dishes where appearance matters.

Research conducted by The Egg Nutrition Center confirms that there is no correlation between eggshell color and nutrient content or flavor. Ultimately, what matters most when selecting eggs is ensuring they come from healthy birds kept in good living conditions – regardless of their external appearance or color.

Why settle for white when you can have a richer shade? Brown eggs may have a thicker shell, but they’re worth cracking open for their satisfying hue.

Brown Eggs:

Brown eggshell color is one of the varieties found among chicken eggs. The color and thickness of eggshells are major factors that affect their aesthetics, cooking, and nutritional properties.

  • Brown eggs get their distinctive hue from pigments like protoporphyrin and biliverdin present in the hen’s uterus walls while forming the eggshell.
  • These eggs are a popular choice for cooking as they possess extra-strong shells that prevent cracking and increase freshness.
  • The hen’s breed, age, nutrition, and environment can influence brown egg production, affecting the shade of brown on the eggshell.

Interestingly, unlike white eggs that have a uniform shade throughout the shell’s surface area, brown eggs have unique patterns or speckles.

A study published by Food Crystals in 2018 revealed that eggshell thickness affects cooking time by prolonging heat transfer up to seven times longer than thin shells.

Why have a blue mood when you can have blue eggs from an Ameraucana chicken? It’s all in the genetics and egg color variation.

Blue eggs

Blue eggs, a unique variation of eggshell colors, are primarily produced by Ameraucana chickens due to genetics. The blue egg color is caused by an absence of pigments, resulting in unpigmented and porous eggshells. These eggs come in various shades ranging from light blue to sky blue.

Apart from the genetic factor, several other factors such as diet and age can also impact the intensity of the blue color. Frequent exposure to sunlight can cause the hue to fade over time.

Interestingly enough, this breed was developed in the US during the 1970s purely for its signature blue eggshell color.

According to research conducted by The Poultry Site, Ameraucana chicken breeds produce vibrant and unique eggs with colors ranging from greenish-blue to bluish-green hues.

Why settle for green eggs and ham when you can have green eggs and Leghorn?

Green eggs

When it comes to egg colors, green eggs are a unique sight. They are rare and not commonly found in the market. The green eggshell color is usually the result of a genetic mutation in certain breeds of chickens like the Araucana, Ameraucana and Easter Egger.

The leghorn chicken egg color is usually white, but when they lay green eggs, it’s because they have inherited the special gene for green pigment on their shells. It’s interesting to note that sometimes the green coloring can be uneven or blotchy on such eggs.

Egg color pigments occur naturally in specific parts of the chicken’s oviducts and get deposited on the shell as it forms. The pigments present determine the final color of an eggshell.

It’s important to note that while some people may seek out these exotic-colored eggs, there is no difference in nutritional value or taste between them and more common white or brown eggs. However, if you are interested in adding some diversity to your carton of eggs, keep an eye out for these elusive hens laying green eggs!

From backyard to cage-free, the color of chicken eggs is affected by genetics, diet, and age, but whether they match your kitchen decor is entirely up to you.

Factors affecting egg color

Let’s explore the 3 sub-sections that explain egg color in backyard, organic, cage-free, and free-range chickens.

  1. Genetics: Breeds and colors of eggs.
  2. Diet: Chicken nutrition and its value.
  3. Age: Factors affecting egg-laying, hatching, and rooster fertility that influence color.


A chicken’s genetic makeup plays a crucial role in determining the color of its eggs. Different breeds of chickens produce various egg colors, ranging from white to dark red. For example, Rhode Island Reds lay brown eggs while Leghorns are known for their white eggs. The difference in genetics leads to egg color variation among different chicken breeds.

The eggshell color is dependent on the pigments present in it, which vary depending on genes inherited from the hen’s parents. According to a study, many genes are responsible for egg coloration. It has been discovered that when two chickens with entirely different genetic backgrounds mate, they produce feathers and plumage that are as unique as their offspring’s shell color.

One unique detail about genetic factors affecting egg color is that some breeds can lay different colors depending on their diet or age. Also, genetic mutations can cause variations in eggshell pigmentation too.

Recently I met a poultry farmer who had bred her own unique strain of mixed-breed chickens. She told me that one interesting fact about genetics was how she selectively chose birds to breed based only on the desired egg color appearance which helped keep the offspring producing similar shades of eggs as previous generations. Choosing and breeding only specific physical traits is critical and takes patience and expertise to develop consistently traceable qualities such as a particular shade of egg every time!

Who needs a multivitamin when you have a daily dose of chicken eggs with all their nutritional value?


The nutrient composition of chicken eggs is closely related to their shell color. The dietary intake of chickens has a significant effect on the pigmentation of their eggs and thus the nutritional value of chicken eggs also varies with respect to egg color.

  • Eggshells are formed from calcium carbonate, and a diet low in calcium can result in thinner eggshells, which makes the eggs more susceptible to breakage.
  • On the other hand, a diet rich in carotenoids such as beta-carotene and lutein can result in darker egg yolks, which contain higher levels of these nutrients.
  • Eating greens like kale, broccoli or spinach may increase the density of nutrients in the yolk.
  • Generally speaking, a well-balanced poultry diet with sufficient protein, vitamins and minerals is necessary for producing high-quality eggs that are nutritious for human consumption.

It should be noted that the variety and quality of dietary options available for chickens vary greatly depending on factors such as location and farm management practices.

Chicken egg nutrition has been an important topic for centuries. Back in the 18th century, Charles Stewart mentioned in his book “The Gentleman Farmer” about experimenting with feeding carrots to hens to improve their egg yolk color. Nowadays, there is extensive research on various aspects of chicken egg nutrition such as their protein content and other beneficial nutrients like choline and selenium.

Why roosters don’t age like fine wine, but hens do brood like it’s nobody’s business.


As chickens age, their egg-laying frequency decreases. This means that younger hens tend to lay eggs with brighter and more vibrant colors than older hens.

In addition to this, as hens grow older, they become more likely to go broody and stop laying eggs altogether. If a hen becomes broody, it will not produce any more eggs until the urge to hatch an egg subsides.

The age of a rooster also affects the color of fertilized eggs. Younger roosters tend to have higher fertility rates and produce darker yolks than older roosters.

It is important to note that while age is one factor that can influence egg color, it is not the only one. Genetics and diet also play significant roles in determining the hue and color intensity of chicken eggs.

Egg Colors Beyond White and Brown

Eggs are available in various colors, beyond the common white and brown ones. These variations in egg colors are attributed to the breed of chickens that lay the eggs. Also, factors such as diet, age, and stress levels of the chicken can affect the color of eggs they lay.

  • Speckled Eggs – These eggs come with tiny brown speckles on the shell, which are a result of genetic inheritance. Like white and brown eggs, they are available in small, medium, and large sizes.
  • Dark-Red Eggs – Some chickens from South America lay eggs with a deep, dark red hue. These eggs are smaller than regular chicken eggs and have a thicker, harder shell. They are often used in specialty dishes and are a subject of cultural curiosity.
  • Chocolate-Brown Eggs – Certain breed of hens, such as the Marans and Welsummers varietals, lay eggs that have a darker and richer brown hue to them. They are much sought after by chefs and consumers alike for their unique color and flavor.

Apart from natural egg color variation, many people enjoy dyeing and decoration of eggs for various occasions like Easter. People often use synthetic or organic dyeing options to create numerous shades, ranging from bright hues to pastel shades. Eggs are also dyed for symbolism, like red eggs for Greek Orthodox Easter or pink eggs for breast cancer awareness.

Furthermore, deviled egg recipes are often tailored to the color of the yolk, with varying flavors and seasonings. Therefore, the color of the yolk is a crucial factor in the overall presentation of the dish.

Lastly, In a small poultry farm, a farmer noticed that the stress levels of the chickens had an impact on the color of the eggs they laid. He discovered that when the chickens were allowed to roam free in an outdoor area, they laid eggs with a bright yellow yolk and darker hue in the eggshell, as opposed to the pale yellow eggs laid by stressed hens. This discovery led to the farmer changing his farming practices and getting better quality eggs.
