Have you ever noticed how supermarket egg cartons often feature a variety of shell colors? This might lead you to wonder: Do Chickens Lay Different Colored Eggs? The answer is a resounding yes!
Let’s delve into the fascinating world of chicken genetics and explore the factors influencing egg color.
Unraveling the Mystery of Egg Shell Colors
While we often associate white with purity and brown with wholesomeness, the truth is that egg shell color doesn’t indicate nutritional value or flavor. The color of an egg solely depends on the breed of the hen.

Genetics: The Driving Force Behind Egg Color
Just like humans inherit hair and eye color from their parents, chickens inherit the ability to lay specific egg colors. The pigment responsible for brown eggshells is called protoporphyrin, which is deposited during the final stages of egg formation.
Fun Fact: Did you know you can sometimes tell what color egg a chicken will lay by looking at their earlobes? For many breeds, chickens with white earlobes lay white eggs, while those with red earlobes lay brown eggs.
Beyond Brown and White: A Spectrum of Colors
While brown and white eggs dominate supermarket shelves, certain chicken breeds lay eggs in a surprising array of hues:
- Blue Eggs: Breeds like the Ameraucana and Araucana, known for their muffs and beard-like facial feathers, lay beautiful blue eggs. This distinct coloration stems from a pigment called biliverdin.
- Green Eggs: When the blue pigment biliverdin combines with the brown pigment protoporphyrin, the result is a stunning olive green egg. This phenomenon is observed in breeds like the Cream Legbar and Olive Egger.
- Pink and Cream Eggs: While not as vibrant as blue or green eggs, some breeds like the Easter Egger and Light Brahma lay eggs with a delicate pink or cream tint. This subtle coloration arises from the varying concentrations of protoporphyrin.

Factors Influencing Egg Shell Color Variation
Even within a specific breed, you might notice slight variations in egg shell color. Several factors contribute to these subtle differences:
- Age of the Hen: As hens age, their egg shells tend to become lighter.
- Diet and Environment: Stress, nutritional deficiencies, and even the amount of daylight a hen receives can impact egg shell color.
- Health: Certain illnesses can also affect the pigmentation process, leading to paler or irregularly colored eggshells.
What About Egg Yolk Color?
Just as genetics determine egg shell color, it also plays a role in yolk color. However, a hen’s diet significantly impacts yolk shade. Chickens fed a diet rich in yellow-orange pigments, such as those found in corn and alfalfa, tend to lay eggs with vibrant orange yolks. Conversely, a diet consisting primarily of wheat or barley results in paler, yellow yolks.

Embracing the Colorful World of Chicken Eggs
So, the next time you’re picking out eggs, remember that the color of the shell is simply a matter of genetics and doesn’t affect the taste or nutritional value. Feel free to experiment with different breeds and enjoy the beautiful variety of colors nature offers!
Frequently Asked Questions
1. Do brown eggs taste different from white eggs?
No, there is no discernible difference in taste between brown and white eggs. The difference in color solely depends on the breed of the chicken.
2. Are blue or green eggs healthier than brown or white eggs?
No, the color of the eggshell does not indicate any difference in nutritional value. All eggs are a good source of protein and essential nutrients.
3. Can a single chicken lay different colored eggs?
No, a single chicken can only lay one color of egg throughout its lifetime. This is determined by its breed and genetics.
4. Why are brown eggs usually more expensive?
The price difference between brown and white eggs is often due to factors like the breed’s size and egg production rate, not necessarily the shell color itself.
5. What should I do if my chickens are laying pale or discolored eggs?
Pale or discolored eggs can indicate stress, nutritional deficiencies, or underlying health issues. Consult a veterinarian for advice on addressing these potential problems.
