From Brown to Blue: The Art of Breeding Chickens for Egg Color
Have you ever wondered why chicken eggs come in a variety of colors?
While most people are familiar with the brown and white shades commonly found at grocery stores, there are actually many other hues that can be produced by breeding chickens. In this article, we’ll explore the fascinating world of breeding chickens for egg color.
The Science Behind Egg Colors
Eggshell color is determined by genetics and pigments that are deposited into the shell as it forms.
There are two main types of pigment responsible for eggshell color: protoporphyrins (which produce reds and browns) and biliverdin (which produces greens).
However, these pigments alone do not determine the final color of an egg; rather, they interact with each other and with environmental factors such as diet and light exposure to create unique shades.
Choosing the Right Chicken Breed
When it comes to breeding chickens for egg color, choosing the right breed is essential.
Some breeds are more likely to lay certain colors of eggs than others.
For example, Araucana chickens are known for their blue eggs, while Ameraucana chickens often produce green or blue eggs.
Other popular breeds for egg color include Marans, which typically lay dark brown eggs, and Leghorns, which tend to produce cream-colored eggs.
Understanding Genetics and Inheritance
To successfully breed chickens for egg color, it’s important to understand how genetics and inheritance work. Just like humans, chickens inherit traits from their parents through DNA.
When it comes to egg color, there are several different genes involved, including the C locus gene, which determines whether an egg will have a colored or clear shell.

By selectively breeding chickens with desirable traits over multiple generations, it’s possible to develop lines of birds that consistently produce specific egg colors.
Tips for Successful Breeding
Breeding chickens for egg color requires careful planning and attention to detail.
Here are some tips for successful breeding:
- Start with high-quality parent stock that has been selected for desired traits.
- Keep detailed records of your breeding program, including which pairs produced which offspring and what their egg colors were.
- Allow plenty of time for your breeding program to take effect – it may take several years before you see consistent results.
- Monitor your flock closely for signs of disease or stress, which can affect egg production and quality.
Breeding chickens for egg color is both an art and a science.
With careful selection of parent stock, understanding of genetic principles, and patient observation, it’s possible to create beautiful and unique eggs that stand out from the crowd.
Whether you’re interested in raising chickens for profit or simply for fun, exploring the world of egg color genetics can be a rewarding experience.
