The Araucana is a rare chicken breed from Chile, best known for its blue eggs, rumpless body, and feathered ear tufts.
Araucanas are easy to recognize once you know their main features. In the U.S. standard, they have no normal tail, may have feathered ear tufts, and are known for laying blue eggs.
They are not difficult chickens to keep, but breeding them can be more challenging than with many other breeds. The ear-tuft gene can affect hatchability, and the rumpless body shape can make some matings less successful.
For backyard keepers, Araucanas can be a good choice if you want an active, interesting bird with blue eggs and do not mind a little extra care when breeding. This guide covers their size, colors, egg production, temperament, care, and the traits that make the breed different from Ameraucanas and Easter Eggers.

What a True Araucana Looks Like
In the United States, four features tell most of the story: blue eggs, ear tufts, a pea comb, and a rumpless rear.
Rumpless means more than having a short tail. The normal tail structure is absent. From the side, the body ends in a rounded slope instead of continuing into the tail you would expect on a Plymouth Rock, Rhode Island Red, or Ameraucana.
The face is just as distinctive. Araucanas do not have the fluffy beard and muffs that cover an Ameraucana’s cheeks. Instead, the feathers grow from small fleshy structures near the ears and project outward as separate tufts.
A bird does not have to be perfectly double-tufted to be useful breeding stock, but if someone is selling you an expensive “show Araucana,” you should know the difference.
Araucana, Ameraucana, or Easter Egger?
Feed stores and online sellers have mixed these names for years, so the confusion is understandable.
| Trait | Araucana | Ameraucana | Easter Egger |
|---|---|---|---|
| Tail | Absent in U.S. standard | Normal tail | Usually tailed |
| Face | Ear tufts | Beard and muffs | Variable, often beard/muffs |
| Comb | Pea | Pea | Often pea-type, but variable |
| Egg color | Blue | Blue | May be blue, green, olive, tan, or another shade |
| Standardized breed? | Yes | Yes | No single APA breed standard |
Araucanas are the easiest of the three to identify from behind because the tail should be missing. Ameraucanas are tailed and have beard-and-muff feathering. Easter Eggers cover a much wider range because they are not one standardized breed.
If a chick is labeled “Araucana/Americana” and grows into a tailed bird with puffy cheeks, you most likely have an Easter Egger. That does not make it a bad chicken. It simply makes it a different chicken.
The Chilean Roots of the Breed
Araucana history can get tangled because birds from Chile were described differently by different people and later standardized in different ways around the world.
Two old Chilean chicken types are often mentioned in the breed’s development. Colloncas were associated with rumplessness and blue eggs. Quetros were known for ear tufts and had tails. Over time, breeders combined those unusual traits.
Spanish poultry expert Salvador Castelló helped bring international attention to Chilean chickens in the early 20th century. From there, breeders in North America, Britain, Europe, and Australia followed different paths. That is why the word “Araucana” does not describe exactly the same show bird in every country.
For a U.S. flock, the American Poultry Association standard is the useful reference point.
Ear Tufts: Beautiful, Unpredictable, and Genetically Tricky
Those tufts are not just ordinary facial feathers.
They grow from fleshy peduncles beside the ears. One bird may have large, balanced tufts. Another may have only one. A third may hatch clean-faced even though it comes from good Araucana stock.
The genetics explain why breeders cannot simply choose the two biggest-tufted birds every time and expect perfect chicks.
The dominant ear-tuft gene is usually written as Et. A chick with one copy can develop tufts. Two copies are generally lethal before hatch. Research has also found higher embryonic losses among tufted heterozygotes than among clean-faced chicks.
So a gorgeous pair of double-tufted adults may produce a disappointing hatch. That is not necessarily an incubator problem.
Breeders often keep clean-faced Araucanas in the program and use carefully planned tufted-to-clean-faced matings. You sacrifice some tufted chicks, but you can improve the odds of getting more live chicks to hatch.
Rumplessness Changes More Than the Silhouette
Removing the normal tail structure changes the entire rear profile of the chicken, and it can affect breeding too.
Natural mating is sometimes less efficient in rumpless birds. If fertility is low, breeders may need to look at body condition, mating behavior, vent feathering, and the compatibility of a particular male and female instead of assuming every clear egg is caused by poor incubation.
Rumplessness has also been associated with developmental and hatchability issues in research. It is better treated as its own genetic problem rather than lumping it together with the lethal tuft gene.
APA-Recognized Colors
For large-fowl Araucanas, the APA recognizes five varieties:
- Black
- Black Breasted Red
- Golden Duckwing
- Silver Duckwing
- White
You will see other colors in breeder flocks, especially outside the show world. That is fine, but “exists” and “APA recognized” are not the same thing.
How Big Are Araucana Chickens?
Araucanas come in both large-fowl and bantam sizes. The standard large fowl are compact birds, but they are not “mostly bantams.”
Standard weights for large fowl are 5 pounds for a cock, 4 pounds for a hen, 4 pounds for a cockerel, and 3.5 pounds for a pullet.
Bantams are much smaller: 28 ounces for a cock, 26 ounces for a hen, 26 ounces for a cockerel, and 24 ounces for a pullet.
That moderate size helps explain why many Araucanas are active foragers and reasonably capable flyers compared with heavier breeds.
Telling a Rooster From a Hen
Forget tail length. Both sexes should be rumpless.
As juveniles mature, males usually show a larger, redder pea comb and a more upright stance. Pointed hackle and saddle feathers become much more useful clues later on. Crowing eventually settles the argument.
Hens stay lighter and rounder through the body. Their saddle feathers remain rounded, and their combs are usually smaller.
Tufts do not tell you the sex. A hen can have enormous tufts, while a rooster from the same line may have only one or none.
Why Araucana Eggs Are Blue
Blue shells are not just brown eggs with a blue coating brushed over the outside.
Biliverdin pigment becomes incorporated into the shell as it forms. Crack a true blue egg and you can see the blue color through the shell instead of finding a plain white interior beneath a colored surface.
Researchers have connected the blue-shell trait with increased activity of the SLCO1B3 gene in the shell gland. A retroviral insertion near that gene is strongly associated with blue eggs in Araucana-derived chickens.
For a standard-bred U.S. Araucana, blue is not just a nice extra. It is part of breed identity.
How Many Eggs Can You Expect?
A productive Araucana hen can give you a respectable basket of eggs without behaving like a commercial laying hybrid.
Mississippi State University Extension uses a figure of roughly 250 eggs per year. For backyard planning, about 200–250 eggs per year is a sensible range for productive lines.
Some hens will be lower. A bird that goes broody, molts hard, reaches winter with little supplemental light, or comes from a show line selected heavily for type may not match the top end of that range.
If your only goal is maximum egg count, a commercial layer will beat the Araucana. Most people choose this breed because the eggs are blue and the chicken itself is unusual.
You can compare other productive breeds in my best egg-laying chickens guide.
Blue Eggs Are Not Lower in Cholesterol
This old claim still turns up surprisingly often.
A blue Araucana shell does not make the egg a special low-cholesterol food. USDA says claims of lower cholesterol in Araucana eggs have not been proven, and controlled research has not supported the myth.
The best reason to enjoy a blue egg is much simpler: it looks great in the egg basket.
Temperament: Busy More Than Cuddly
Araucanas tend to be alert chickens. Give them a yard and they usually find something to investigate.
That does not mean they are difficult birds. Many settle nicely around people when handled calmly from a young age. They may walk over for feed, follow the normal flock routine, and become easy to catch without turning into lap chickens.
Individual personality matters. So does the breeder. A line selected from calm parents can feel very different from one in which temperament has never been part of the selection process.
If you specifically want birds chosen for easygoing behavior, see the friendliest chicken breeds.
Broodiness Can Go Either Way
Some Araucana hens will sit. Some will not.
There is enough variation between lines that I would not buy the breed specifically because you want a guaranteed broody hen. If natural hatching matters to you, ask the breeder whether the females in that family regularly sit and raise chicks.
Even a determined broody cannot overcome lethal tuft genetics. Poor hatch results can come from the mating itself, not from the hen’s mothering ability.
Free Range, Fencing, and Flying
Araucanas usually make good use of outdoor space. They scratch, forage, chase insects, and stay fairly active through the day.
Their moderate weight also means some can clear fencing that would stop a Brahma or other heavy breed. If your birds repeatedly visit the neighbor’s garden, taller fencing or a covered run may solve more problems than wing clipping.
Free range is not free nutrition. Even a good forager still needs a balanced poultry ration as the base of the diet.
Feeding and Everyday Care
There is no special feed that makes an Araucana lay a bluer egg.
Start chicks on a complete starter ration. Move growing pullets to an appropriate grower or developer feed, then use a complete layer ration once hens reach production age.
Fresh water matters just as much as feed, especially in hot weather. A hen that is short on water can reduce laying quickly.
If the flock eats whole grains or spends a lot of time foraging, provide appropriately sized insoluble grit. Laying hens can also have free-choice oyster shell for extra calcium.
Those are two different supplements. Grit helps grind coarse foods in the gizzard. Oyster shell supplies calcium.
For a more complete feeding routine, see my guide to feeding chickens.
Coop Space and Weather
Araucanas do well with ordinary good chicken housing. Keep it dry, ventilated, secure from predators, and roomy enough that the flock is not constantly stepping over one another.
For large fowl, around four square feet of indoor coop space per bird is a practical starting point when they also have a good run. More space is useful during long stretches of rain or snow when the birds spend extra time indoors.
The pea comb and small wattles expose less tissue than the large comb of a Leghorn, so winter frostbite risk is lower. It is not zero. Damp air, wet bedding, and frozen drinking water can still make winter miserable.
Summer is simpler: shade, moving air, and plenty of cool water. Panting, drooping posture, wings held away from the body, or a sudden drop in appetite tells you the heat is getting ahead of the bird.
If you are planning a new setup, my guide to chicken space requirements gives a broader starting point.
Health Problems to Watch
Adult Araucanas do not need an exotic health routine just because their genetics are unusual.
Watch for the same things you would in any flock: mites, lice, worms, respiratory disease, injuries, poor body condition, and reproductive problems. The ear tufts can hide irritated skin near the ears, so it is worth parting the feathers occasionally instead of only looking at the bird from a distance.
The breed’s biggest special challenge happens before hatch. The Et gene can kill embryos, which is a breeding problem rather than a chronic illness in the adult chicken.
Severe weakness, repeated straining, abdominal swelling, persistent respiratory signs, or unexplained weight loss deserve veterinary or diagnostic help rather than guesswork.
Breeding Araucanas Is Where the Work Begins
Keeping a few Araucanas is not especially difficult. Breeding good ones is another story.
You are balancing several things at once: blue egg color, rumpless type, body shape, comb, variety color, tuft quality, fertility, and hatchability.
A clean-faced breeder may be more valuable than it looks if it produces strong chicks and helps avoid lethal tuft-to-tuft combinations. A spectacular show bird may be disappointing if its matings repeatedly give poor fertility.
Keep records. Write down which pair produced which chicks, how many eggs were fertile, how many embryos quit, and what the surviving birds looked like as adults. With this breed, memory gets unreliable very quickly.
If you only want an easy flock that reproduces predictable blue-egg layers year after year, a well-established Ameraucana line may suit you better. Araucana breeding rewards patience more than convenience.
Pros and Cons
- Blue eggs: a defining breed trait, not just a novelty.
- Unusual appearance: rumpless body and ear tufts make the breed instantly recognizable.
- Useful laying: productive lines can reach roughly 200–250 eggs per year.
- Good activity level: often enjoyable birds for keepers who like foraging chickens.
- Moderate size: easier to house than very large dual-purpose breeds.
- Harder to source: true standard-bred Araucanas are much less common than Easter Eggers.
- Breeding is demanding: tuft genetics and rumplessness can reduce fertility and hatchability.
- Mislabeling is common: many chickens sold as Araucanas do not meet the U.S. standard.
Frequently Asked Questions
Is an Araucana a hybrid?
No. The Araucana is an established APA-recognized breed.
Do Araucanas have tails?
Not in the U.S. standard. A proper APA Araucana is rumpless and lacks the normal tail structure.
Do Araucanas have beards and muffs?
No. They have ear tufts. Beard and muffs are characteristic of Ameraucanas and are also common in many Easter Eggers.
What color eggs do Araucanas lay?
True U.S. Araucanas should lay blue eggs.
Are blue Araucana eggs lower in cholesterol?
No reliable evidence shows a cholesterol advantage simply because the shell is blue.
How many eggs does an Araucana lay?
Productive lines can lay roughly 200–250 eggs in a good year, although individual hens may produce less.
Why are Araucanas difficult to hatch?
The dominant ear-tuft gene is lethal when an embryo inherits two copies. Rumplessness can also complicate breeding and fertility.
Are Araucanas friendly?
Many are easy to manage with calm, regular handling. They are usually better described as active and curious than guaranteed cuddly pets.
Should You Add Araucanas to Your Flock?
If you just want a hen that lays blue eggs, you can get there more easily with an Ameraucana or Easter Egger.
The Araucana makes sense when the bird itself matters as much as the egg. You are getting a recognized breed with a tail-less body, unusual ear tufts, a long Chilean history, and genetics that can keep a breeder humble.
Buy from someone who knows the difference between an Araucana and an Easter Egger. Ask to see the parent birds if possible. Ask what color eggs the hens lay. If you plan to breed, ask about fertility and hatch rates too.
Good Araucanas are not the easiest blue-egg chickens to find or reproduce. That is part of what makes them worth preserving.
