Araucana

The Araucana is a medium-sized chicken breed that started in South America and has since found favor among raisers who want something out of the ordinary. Two features set it apart from the usual backyard chicken: it lays blue-shelled eggs, and most birds grow feather tufts from small flaps of skin near the ears. A good number of Araucanas are also rumpless, meaning they have no tail bone and none of the long tail feathers common on other breeds.

The blue shell color comes from a pigment called oocyanin, deposited through the whole thickness of the shell rather than sitting only on the surface. Crack one open and the inside of the shell is blue too. This trait set the Araucana apart from ordinary brown-egg and white-egg stock and later became the base for several blue-egg and green-egg hybrids that are now common in backyard flocks.

Temperament-wise, the Araucana is independent, curious, active, and always alert to what is going on around it. It forages well and stays watchful, which suits free-range setups or a roomy run better than a small cage, especially in a tropical backyard where birds are usually let out to range during the day.

Who it suits

The Araucana suits a raiser who wants an unusual egg color and a bird that largely looks after itself. It thrives with room to range and keeps busy on its own, which fits many Philippine backyards where chickens share the yard with vegetables and fruit trees. The tufting and rumpless genes bring breeding complications (see Health and Hatching below), so anyone planning to hatch chicks should understand these lethal-gene issues before starting.

The Araucana takes its name from the Araucania region of Chile, home to the Indigenous Mapuche people, who kept chickens that laid colored eggs long before the breed had a name. Early records describe two separate local types, one with ear tufts and one rumpless. These traits were later combined into a single recognized breed, and the precise origin of the foundation stock is still not settled.

The breed reached a wider audience in the early 1900s. Spanish poultry researcher Salvador Castello studied Chilean chickens in the 1910s and wrote about the blue eggs for an international readership, which is how poultry keepers outside South America first learned of the trait.

From the 1920s onward, breeders in Europe and North America imported and worked with these birds, and each region ended up developing the breed along its own lines. That is why the Araucana standard is not the same everywhere. In the United States the breed entered the American Poultry Association Standard of Perfection in 1976, defined there as both rumpless and tufted. British and some European standards instead describe a tailed, crested bird, so the same breed name covers noticeably different birds depending on which country wrote the standard.

Because both the tufting gene and the rumpless trait carry inheritance risks, the Araucana also became the base stock for crossbreeds such as the Easter Egger and, later, the Ameraucana, both of which keep the blue-egg trait without the lethal-gene complications. These crosses are the ones most backyard raisers in the Philippines are likely to encounter, since true Araucanas remain a specialty bird here.

The Araucana is a compact, medium-sized bird that carries itself upright and alert. Two features mark the breed at a glance: the ear tufts, which are clusters of feathers growing out of skin flaps just below the ears, and the rumpless back, where the tail and tail bone are missing entirely so the body line curves smoothly at the rear instead of ending in a tail. Not every bird shows both traits at once, and standards differ from country to country.

The comb is a small pea comb that sits low against the head. This comb type is not especially relevant to Philippine conditions, where frost is never a concern, but it does keep the head compact and tidy. The face is clean, and the bird carries a full, hard-feathered body that sheds rain reasonably well during the wet season.

Coat and colors

The Araucana is recognized in a wide set of plumage colors. Common varieties include black, white, blue, black-breasted red, silver duckwing, and golden duckwing, though the exact accepted list depends on which standard is being used. Skin and shanks usually run willow or slate rather than yellow. The feathering sits tight against the body and sheds water well, which helps during the rainy season provided the coop itself stays dry.

The Araucana is an active, alert bird that would rather keep moving than sit still. It forages well, covers a good stretch of ground when allowed to range, and stays aware of threats from above and on the ground, all of which make it a capable free-range chicken for a typical backyard setup. The breed is independent and does not need constant attention, so it tends to manage itself within a flock.

Around family members and regular handlers, Araucanas can settle down and grow used to people, particularly when handled gently and often from chick age. They are not lap chickens as a rule, and the more high-strung individuals can startle easily or turn flighty when kept in tight quarters. With strangers they stay watchful rather than aggressive, more likely to keep their distance than to charge.

Within mixed flocks and around other backyard animals, the breed usually settles in without much fuss under calm handling, though its alert nature means it reacts fast to any disturbance. Because it dislikes close confinement, a cramped run is far more likely to produce boredom and stress than an open yard would.

The Araucana is a hardy breed that needs the usual poultry care plus enough space to satisfy its active, foraging habits. Its tight feathering helps it shed rain, and the pea comb is never troubled by frost in a Philippine setting, but the bird still needs dry, well-ventilated housing and solid protection from predators, especially during typhoon season when flooding and wind damage are real risks.

Grooming

• Set up a dry dust-bathing spot so birds can look after their own feather and skin condition, even during the wet months when dry ground is harder to find.
• Check the ear tufts and the skin around them during routine handling, since this area can be sensitive.
• Inspect the vent, feet, and feathers regularly for mites and lice, which spread quickly in humid conditions.
• Trim nails or spurs only if overgrowth is getting in the way of normal movement.

Exercise

• Give the birds daily free-range time or a large run; this breed does poorly when kept in tight confinement.
• Provide perches and varied ground cover to support natural foraging and roosting behavior.
• Use a secure fence or covered run, since active birds can turn flighty and may attempt short flights over low barriers.

Environment

House Araucanas in a coop that stays dry and well ventilated without being drafty, ideally raised slightly off the ground to avoid flooding during heavy rain. The pea comb is rarely an issue for cold in a tropical climate, but wet bedding and poor airflow cause respiratory and foot problems regardless of season. Provide shade, cross ventilation, and a steady water supply during the hot months, and check the roof and fencing before typhoon season starts. A predator-proof coop and run matter as well, since alert, ranging birds spend a good part of the day away from cover.

Feed the Araucana a complete commercial poultry feed suited to its life stage. Chicks need a starter mash or crumble, growers need a grower feed, and laying hens need a layer feed that supplies the extra calcium required for strong shells. Birds that range will pick up insects and greens on their own, but a balanced commercial feed should stay the base of the diet, not an afterthought. Provide insoluble grit so the gizzard can grind feed properly, and give layers a separate calcium source such as crushed oyster shell or ground snail shell, both of which are easy to find in most feed stores.

Treats and supplements

Keep treats to roughly 10 percent of the daily diet so they do not throw off the balance of the complete feed. Good extras include leafy greens such as kangkong or malunggay, cooked rice or other grains, and small amounts of mealworms or other insects. Fresh water must be available at all times, and layers should have constant access to a calcium supplement to keep shell quality up.

As an adult bird the Araucana is hardy and copes well with humid, warm conditions once it has dry shelter and shade. A typical lifespan runs 7 to 8 years with good husbandry. The breed's main health concerns are genetic rather than environmental, and they show up mostly in breeding and hatching rather than in day-to-day care.

The ear-tuft trait is tied to a lethal gene. Chicks that inherit two copies usually die before hatching, which is why tufted-to-tufted matings produce lower hatch rates than expected. The rumpless trait, and the shape of the rear vertebrae that goes with it, can also lower fertility because it changes the angle at which mating happens. These are inherited issues to plan breeding around, not illnesses that need treatment.

Preventive care

• Keep housing dry and well ventilated to head off respiratory and foot problems, particularly during the rainy months.
• Check for mites and lice during routine handling and treat early, since parasites multiply fast in heat and humidity.
• Provide layer-appropriate calcium to prevent soft shells and reproductive strain.
• Quarantine new birds before adding them to the flock.
• Plan matings carefully to avoid doubling up the tuft gene (see the Hatching section).

The Araucana does best in a secure coop paired with as much outdoor range as the yard allows. The coop should stay dry, allow good airflow without drafts, and lock up tight at night against predators, which in many Philippine backyards means dogs, cats, rats, and the occasional snake as much as birds of prey. Because the breed is active and dislikes confinement, the attached run or free-range area matters just as much as the coop structure itself. Provide roosting bars for the night and clean nest boxes for laying.

Setup checklist

• Dry, ventilated coop with a solid roof and a secure door.
• Roosting bars set above the nest boxes, not beside them.
• Clean, bedded nest boxes tucked in a quiet corner.
• Large run or supervised free-range area for daily foraging.
• Dust-bathing spot with dry, loose substrate, refreshed after heavy rain.
• Predator-proof fencing or a covered run, plus shade and a steady water supply.

Araucana eggs incubate on the same schedule as other chicken eggs, hatching at about 21 days given the right temperature and humidity. The breed's real challenge is genetic rather than procedural. The tuft gene is lethal in its double form, so pairing two tufted birds costs a good number of embryos before hatch. To keep hatch rates workable, breeders commonly pair a tufted bird with a clean-faced (non-tufted) bird, which avoids doubling the gene while still producing tufted chicks in the next generation. Fertility can also run lower than average in rumpless birds because of how the rear shape affects mating.

Hatching steps

1. Select fertile eggs from a planned mating (commonly tufted by clean-faced) and store them pointed-end down for no more than about a week before setting.
2. Get the incubator stable at 37.5 C and the correct humidity before adding eggs.
3. Turn the eggs several times a day through day 18.
4. At day 18 stop turning, raise the humidity for hatch, and leave the incubator closed through lockdown.
5. Let the chicks hatch and dry off fully before moving them to a warm brooder with starter feed and water.
