Which Chickens Lay Blue Eggs?

Are you curious about which chickens lay blue eggs? Keep reading to learn about these unique breeds, what factors influence egg color, and how to welcome these fascinating birds to your flock.

Which Chickens Lay Blue Eggs?

Blue eggs are produced by chicken breeds such as the Ameraucana, Araucana, and the Cream Legbar. These unique breeds are known for their distinctive blue egg-laying abilities and make a colorful addition to any flock.

Three unique breeds with blue egg-laying abilities

There are a few chicken breeds that lay blue eggs, and each of these breeds brings something special to your backyard flock. These breeds are Ameraucana, Araucana, and Cream Legbar. Let’s explore what makes each of these breeds unique and why they lay such interesting eggs.


The Ameraucana, often mistaken for the Araucana, is a beautiful and hardy breed with a variety of plumage colors. What sets them apart from other chickens is their blue or blue-green eggs. The Ameraucana is known for being friendly, making them an excellent choice for families with children.


Originating from South America, Araucanas have some fascinating features, including ear tufts, which are clumps of feathers that grow from a fleshy area near their ears. These chickens don’t have tails, but they are adorned with beautiful large wings. They lay beautiful blue eggs, which is one of the reasons they’re sought after by chicken enthusiasts.

Cream Legbar

Native to the United Kingdom, Cream Legbars are an autosexing breed, meaning it’s easy to tell the gender of the chicks at the time of hatching. They’re friendly, active, and intelligent birds, laying a high number of large blue or blue-tinted eggs. Cream Legbars are great foragers, making them a fantastic addition to a free-range flock.

What affects the blue color of the eggs?

The blue color of the eggs laid by these breeds is due to the pigment oocyanin, which is a byproduct of bile production. This pigment is deposited on the eggshell early in the egg-laying process.


One of the main factors affecting egg color is genetics. The gene responsible for blue eggshells is dominant. However, the color can vary based on the specific genetic makeup of the hen.


Although diet doesn’t significantly impact the blue color of eggs, a balanced and nutritious diet helps ensure strong eggshells and vibrant yolks. Feeding your hens a layer feed designed specifically for egg-layers is essential.


Stress can be a factor in variations in egg color. A stressed hen might lay eggs that are lighter in color or even white. It’s essential to maintain a calm and comfortable environment for your hens to ensure they continue laying beautiful blue eggs.

Adding blue egg layers to your flock

If you’re thinking about adding some blue egg layers to your flock, consider your options and how these breeds will fit in with your existing birds.

Space requirements

Each chicken breed has specific space requirements, and it’s essential to provide them with enough room to ensure their comfort and well-being. Although blue egg layers aren’t overly large birds, they enjoy the freedom to explore and forage, so ample space is necessary to keep them happy.


All three blue egg-laying breeds are known for being friendly and good-natured. When adding these chickens to your existing flock, observe them closely and monitor their interactions to ensure a smooth integration. Each breed may have slightly different temperaments, so consider what will work best with your current flock’s dynamic.

Purchasing chicks or hens

Whether you purchase chicks or adult hens depends on your experience level and personal preferences. Chicks can be much more cost-effective than adult hens, but they require more care and attention. You should take into account whether you want to raise chicks or simply enjoy the immediate benefits of adding mature hens to your flock.

Feeding and caring for your blue egg-layers

Proper care and feeding are essential to ensure your blue egg-laying hens remain healthy and productive. A few key elements can help maintain your birds’ health and happiness.


Feeding your birds a balanced diet with the appropriate nutrients is important for their overall health and egg production. Layer feed provides the necessary nutrients, while treats like fruits, vegetables, and mealworms add variety to their diet.

  • Layer feed: Feed your hens a high-quality layer feed, which contains necessary nutrients like protein, calcium, vitamins, and minerals.
  • Chick starter: If you’re raising chicks, start with a chick starter feed for the first six to eight weeks before transitioning to a grower feed until they are of laying age (16-20 weeks old).
  • Grit: Chickens also require grit to help digest their food efficiently. You can provide this separately or find feed that already includes grit in the mix.


Ensuring your chickens have constant access to fresh, clean water is vital. Remember to check and refill water containers daily, cleaning them as necessary to prevent bacteria buildup.

Shelter and safety

A safe, secure, and comfortable coop is crucial for your blue egg-laying hens. Equip the coop with a roost, nesting boxes, and clean bedding. A securely enclosed run can prevent predators from harming your flock and provide the necessary space for your chickens to explore.

FAQs about blue egg-laying chickens

Do blue eggs taste different from white or brown eggs?

Many people wonder if blue eggs taste differently than other eggs. The truth is that the color of the eggshell doesn’t affect the flavor or nutritional content of the egg. Factors influencing taste and nutritional content include the hen’s diet, overall health, and living conditions.

Do blue eggs need special care?

No, blue eggs don’t require special care compared to other eggs. They might be different in appearance, but you can treat them the same way as regular eggs. Collect your blue eggs regularly, store them in a cool and dry place, and wash them just before using.

Are blue eggs healthier than brown or white eggs?

While there’s no significant nutritional difference between blue eggs and eggs of other colors, the health of the chicken that laid the egg plays a role in the egg’s nutritional content. A well-cared-for, healthy chicken laying blue eggs will produce nutritious and delicious eggs just like any other healthy chicken.

Benefits of raising your own blue egg-producing chickens

Raising your own chickens that lay blue eggs comes with a variety of benefits:

  • Variety: Blue eggs add an appealing aesthetic to your egg collection, making them a fun and interesting addition to your flock.
  • Conversation starter: The unique egg color is a great conversation starter, and people will be intrigued by your blue egg-laying hens.
  • Nutrition and taste: As with any homegrown eggs, blue eggs from your backyard chickens tend to be fresher, tastier, and more nutritious than store-bought ones.
  • Eco-friendly: Raising backyard chickens is an environmentally-friendly choice, reducing waste and providing natural fertilizer for your garden.

In conclusion

Chickens that lay blue eggs add diversity, beauty, and curiosity to your backyard flock. With breeds like Ameraucana, Araucana, and Cream Legbar, there are several options for introducing these unique egg-layers to your coop. By understanding the factors that influence egg color, providing proper care and nutrition, and helping them integrate well with your existing flock, these blue egg-laying chickens will be an excellent addition to your backyard chicken-keeping experience.

Crossbreeding for blue egg-laying chickens

Another exciting aspect of raising chickens that lay blue eggs is the possibility of crossbreeding them with other chicken breeds. Crossbreeding can lead to unique plumage and egg colors, adding even more diversity to your flock.

Blue egg layers and Olive Eggers

One popular crossbreed includes crossing a blue egg-laying breed like an Ameraucana or Araucana with a dark brown egg-laying breed like a Marans or Welsummer. The offspring of this combination, known as Olive Eggers, tend to lay large olive green eggs, taking after both of their parents’ egg colors.

Blue egg layers and Easter Eggers

You might have also heard of Easter Eggers, which are not a true breed but rather a hybrid chicken that can lay blue, green, and sometimes even pinkish eggs. These birds are often produced by crossing blue egg layers like Ameraucanas, Araucanas, or Cream Legbars with other breeds, resulting in a fascinating range of eggshell colors.

Maintaining a breeding program for blue egg layers

If you’re interested in breeding blue egg-laying chickens, you’ll want to plan and maintain a proper breeding program to generate the best results. Some factors to consider are:

  • Space: Ensure you have ample space for breeding pairs or groups and room to separate the different breeds or hybrids to prevent unwanted crossbreeding.
  • Genetics: Select chickens with the best genetic traits for blue egg laying and other desired characteristics like temperament and appearance.
  • Record keeping: Keep detailed records of your breeding program, such as the parentage of each bird, the egg color outcomes, and the overall health of your birds.
  • Managing the offspring: Plan and care for the offspring resulting from your breeding program, ensuring they have the necessary space, shelter, and nutrition to thrive.

Understanding and managing broodiness in blue egg layers

Another consideration when raising blue egg-laying chickens and breeding them is to manage broodiness. Broodiness is a natural behavior in hens, where they remain on the nest to incubate their eggs until hatching.

When managing a breeding program or simply raising blue egg layers, you might want to encourage or discourage broodiness. Encouraging broodiness aids in natural hatching and raising offspring, whereas discouraging it ensures steady egg production.

Encouraging broodiness

If you want your hens to become broody, place a few fake eggs in their nest boxes to trigger their instincts. Additionally, providing a comfortable, private space where the hens feel secure is essential.

Discouraging broodiness

If you prefer to focus on egg production and avoid broodiness, remove eggs from the nesting boxes daily. You can also block the nesting box temporarily or move a broody hen to a new area without a nest, deterring her from nesting behavior.

By considering all aspects of raising blue egg-laying chickens, crossbreeding possibilities, breeding programs, and managing broodiness, you will create a thriving and diverse backyard flock, enjoying beautiful blue eggs from your hens.
