15 interesting facts, all about the Araucana Chickens

The Araucana chicken isn’t just another blue egg layer. It’s a true heritage breed, naturally rumpless, and a rare breed to find in someones homestead or backyard flock. If you think the Ayam Cemani is a unique breed, you haven’t met the Araucana.

1. The Araucana is a True Blue Egg Layer

This is one of the blue egg-laying breeds; they carry the blue egg gene, and all offspring will be guaranteed to lay blue eggs. Araucanas get grouped into the blue gene-carrying breeds along with the Ameraucana, Cream Legbar, and Whiting True Blue.

2. They Are Naturally Rumpless

The Araucana chicken is known for its unique appearance. One of their most striking features is the small feathered ear tufts on either side of their head. But what really sets them apart is their rumpless phenotype — meaning they naturally lack a tail.

That’s right. No tail feathers. No tailbone.

This combination of ear tufts and a naturally rumpless body gives the Araucana its unmistakable silhouette and is one of the defining traits of the breed.

3. They Have Ear Tufts — Not Muffs

As mentioned above, Araucanas have a very distinctive look. They have ear tufts — not muffs — on either side of their head. These tufts are small clusters of feathers that grow from a fleshy appendage near the ear canal, which is very different from the fluffy cheek “muffs” seen on breeds like Easter Eggers or Ameraucanas.

They are the only chicken breed recognized by the American Poultry Association that has true ear tufts, making this one of the most defining characteristics of the Araucana.

4. The Ear Tuft Gene Is Lethal

One of the most fascinating — and challenging — things about Araucanas is the ear tuft gene itself.

The gene that causes those beautiful ear tufts is what’s known as a lethal gene. If a chick inherits the tuft gene from both parents, it often will not survive to hatch. In simple terms, breeding two tufted Araucanas together can result in a high number of embryos that die before they ever make it out of the shell.

Because of this, hatch rates can be lower than with other chicken breeds. Even experienced breeders must carefully plan pairings, often breeding a tufted bird to a non-tufted bird to improve viability.

This genetic challenge is one reason why Araucanas are rare and why their numbers remain low. They simply aren’t as easy to breed successfully as many other backyard chicken breeds.

5. They Are Recognized by the American Poultry Association

Having an official breed standard is what separates a true breed from a mixed backyard cross. The Araucana is recognized by the American Poultry Association, meaning it meets specific standards for traits like rumplessness, ear tufts, body type, and color varieties.

This recognition confirms that the Araucana is a standardized, established breed — not just a chicken that happens to lay blue eggs. Breed standards help preserve the integrity and consistency of the Araucana, especially since it is often confused with Easter Eggers or Ameraucanas.

6. They Are a Heritage Breed

A heritage breed is a traditional livestock breed that has been around for generations, developed through natural breeding rather than modern commercial hybrid programs. Heritage breeds reproduce naturally, grow at a normal rate, and maintain the genetic traits that were carefully selected over time.

In simple terms, they are the original breeds, not crosses designed for mass production.

7. They Are Listed on the Livestock Conservancy Watch List

In 2025, the Araucana was added to the Critical list by The Livestock Conservancy. According to the 2025 Conservation Priority List Special Section newsletter, there are an estimated 400 Araucana birds remaining, with only about 50 breeding flocks — all in private hands.

That number should make any poultry keeper pause.

This unique heritage breed is not being maintained by large hatcheries or commercial producers. Its future depends on small breeders and dedicated flock owners.

For a homesteader who wants to do more than just collect pretty eggs, the Araucana presents an opportunity. Responsible breeding, careful selection, and maintaining proper standards can help strengthen population numbers and preserve this rare chicken breed for future generations.

8. Araucanas are Internationally Recognized

The Araucana is a breed of chicken that has gained global recognition and been exported to various countries worldwide.

Today, many enthusiasts and breeders from countries like the United States, the United Kingdom, and Australia are actively involved in raising and breeding Araucana chickens, contributing to preserving and promoting the breed.

9. They Are Not the Same as Ameraucanas

Although both breeds lay blue eggs, Araucanas and Ameraucanas are not the same. The Araucana is naturally rumpless and has ear tufts, while the Ameraucana has a full tail and muffs instead of tufts — making them two distinct, recognized breeds.

However, both breeds do carry the blue egg gene responsible for their shell color.

10. Araucanas Are Cold-Hardy

 Araucana chickens are generally considered to be cold-hardy. Araucanas have adapted to withstand colder climates with proper care.

These chickens typically have dense plumage that provides insulation against cold temperatures, helping them to maintain their body heat.

Additionally, Araucanas have small pea combs and are less prone to frostbite than chicken breeds with larger combs.

While Araucanas can tolerate colder temperatures well, providing appropriate shelter and bedding is essential during particularly harsh weather conditions. 

11. They Come in Limited Recognized Colors

The American Poultry Association only recognizes a handful of colors (varieties), unlike other chicken breeds. Maybe because they are so rare that no one has spent the time to work on approving other varieties. Here are the varieties approved by APA Standards: Black, White, Black Breasted Red, Silver Duckwing, and Golden Duckwing.

Breeders may have Araucanas in many different colors, but they are not approved by the APA, so showing them in professional poultry shows would not be allowed; they would have to be shown in the open class.

12. Araucanas are Athletic and Alert

Don’t let their critical conservation status fool you — Araucanas are anything but fragile. They are active, alert birds that are always aware of their surroundings. They tend to be a bit more independent and quick on their feet, which makes them excellent foragers. These aren’t lazy backyard chickens; they’re smart, watchful, and always paying attention.

13. They are Good Egg Layers

The egg production of Araucana chickens can vary depending on certain factors. Araucana hens typically lay 150 to 200 eggs per year under prime conditions.

Araucana chickens lay fewer eggs than commercial breeds bred for high egg production, like Leghorns or Rhode Island Reds.

14. They Are Rare in Hatcheries

Araucanas are rarely found in large hatcheries because they are difficult to breed successfully. Between the lethal ear tuft gene and lower hatch rates, they simply aren’t as easy to produce in high numbers as other backyard breeds.

Most commercial hatcheries focus on breeds that hatch consistently and sell easily — which is why true Araucanas are usually found through small, dedicated breeders instead.

15. They Are One of the Most Misunderstood Chicken Breeds

Araucanas are one of the most misunderstood breeds when it comes to breeding. They aren’t as simple as tossing a rooster in with a few hens and waiting for chicks.

Because of the lethal tuft gene and lower hatch rates, careful pairing really matters. It takes patience and a breeder who understands what they’re working with.

Frequently Asked Questions

Are Araucanas raised for meat?

Araucana chickens are known for their colorful eggs and are raised for meat and egg production. They are considered dual-purpose birds. But in my experiance even dual-purpose chicken breeds do not yield alot of meat, they are better for stock or soups.

How many eggs a year do Araucanas lay?

The egg production of Araucana chickens can vary depending on factors such as individual genetics, nutrition, environment, and age. Araucana hens typically lay 150 to 200 eggs per year under optimal conditions.

What colored eggs do the Aruancans lay?

Araucana chickens are known for laying eggs with shells ranging from pale blue to greenish-blue. The shade of blue can vary among individual hens and can be influenced by genetics and diet.

This unique egg coloration sets Araucana eggs apart from most other chicken breeds, which typically lay eggs with white or brown shells.

What does the Araucana chicken look like?

The Araucana chicken is known for its distinctive and unique appearance, characterized by several notable features:

• 1. Ear Tufts (some may lack them)
• 2. Rumpless
• 3. Pea Comb
• 4. Small or no Wattles

Feel free to drop me a comment if I somehow missed interesting facts about this amazing breed.

Due to their rarity and the higher cost of chicks, I have yet to add an Araucana to our flock. However, I would truly love to bring a few home someday just to see for myself how blue their eggs really are.

If you aren’t ready for the commitment or expense of a true Araucana, I would recommend looking into Ameraucanas or even Easter Eggers as an alternative. Both can add beautiful blue or colorful eggs to your flock while being more widely available and often easier to find.
