Heritage landrace breeds like the Swedish Hedemora chicken are gaining popularity among backyard poultry keepers for their unique history and robust health.
This breed comes from the sub-Arctic forests of northern Europe and is famous for its extreme cold-hardiness.
Unlike commercial hybrids, the Hedemora has developed naturally over centuries and is a compact, self-sufficient bird with dense insulating plumage.
This guide traces the breed’s journey from near extinction to its place as an important part of any cold-weather homestead.
History and Origin
The Hedemora chicken has a long agricultural history of more than 500 years, and its geographical origin is in the heavily forested Dalarna County in Sweden.
These fowl, expert foragers, were an integral part of the traditional Swedish rural lifestyle for centuries, thriving in free-range settings.
Swedish Hedemora chickens were so culturally prized that flocks were often given to newlyweds as wedding gifts, symbolizing prosperity and a secure home.
Despite their significance, the mid-20th century shift toward industrial farming marginalized small-scale agriculture and brought the breed to the brink of extinction.
By the late 1970s, the original Hedemora was believed lost. However, in the 1980s, conservationist Viola Forsberg discovered a small, isolated remnant flock near the village of Trollbo, saving the breed and providing the genetic foundation for its modern revival.
After the rescue, the Svenska Lanthönsklubben implemented strict conservation programs and gene banks to protect the remaining birds. They were more concerned with natural care and not a standardized appearance to maintain genetic robustness.
Recent genetic research shows that the Hedemora is unique and forms a separate cluster together with the Öländsk dvärghöna. Today it is a celebrated heritage breed, preserving important agricultural biodiversity.
Chicken Lifespan
Swedish Hedemora chickens have a natural life span that is longer than today’s commercial hybrids, which often wear out by three years of age.
Average backyard hens will live to be 6 to 8 years old, but hardy Hedemoras often live to be 8 to 10 years old. Avian longevity can be high under low metabolic stress. The world record age is 16 years.
Hens reach maturity at 18 to 22 weeks and peak production at about 30 weeks. Egg size increases during the first year, but total volume decreases each year after that.
Output is about 80% in the second year, 70% in the third year, and 60% in the fourth. Old Hedemoras are still valuable, however, for their foraging skills and mothering abilities, despite the reduced yields.
Managers often bring in young pullets every two to three years to keep flock production consistent.
| Age of Hen | Expected Production Volume | Lifespan Milestones |
| 0 – 22 Weeks | Pre-production (Growth) | Sexual maturity reached |
| Year 1 | 100% (Peak Production) | Highest volume of eggs |
| Year 2 | ~80% of Year 1 volume | Egg size stabilizes |
| Year 3 | ~70% of Year 1 volume | Production naturally slows |
| Year 4+ | ~60% of Year 1 volume | Enters productive retirement |
| Year 8 – 10 | Minimal to no egg production | Average senior life expectancy |
Swedish Hedemora Chicken Recognized Variety
The Swedish Hedemora is a landrace breed, so there are no strict show standards like those set by the American Poultry Association.
By contrast, its appearance was forged by centuries of natural selection in the sub-Arctic, where survival trumped aesthetics.
Conservationists say all three types of feathers must be preserved to keep genetic diversity.
- Wooly (Wooly-Silky): These birds have soft, wool-like feathers like Silkies. Each feather is coarse on top and downy on the bottom. In addition, it is a fur-like thermal insulator against cold winds.
- Smooth (Hard-Feathered): Featuring traditional, flat-lying feathers, these birds appear streamlined while concealing thick, warm under-down.
- Leg Types: Hedemoras are divided into clean-legged and feather-legged, regardless of body feathering.
Physical Characteristics of Swedish Hedemora Chickens
All the physical attributes of the Hedemora are biologically adapted to survive in extreme cold. Their big, compact bodies reduce exposed surface area to help retain internal heat, and their very short legs keep their core close to the ground, reducing exposure to the freezing elements.’
The Hedemora have developed very small facial appendages to avoid frostbite, which is a big problem in freezing climates. Both the hens and roosters have small to medium straight single combs and small wattles, so the area exposed to freezing is greatly reduced.
Skin and bone pigmentation is another fascinating area of physical variation. While some birds have standard white or pinkish skin, a large portion carries a genetic trait known as fibromelanosis. This mutation causes the skin, shanks, internal organs, and bones to appear extremely dark—ranging from deep grey to solid black.
The same pigmentation is also present on the birds’ legs: light-skinned birds have white legs, while fibromelanistic birds have black or blue-grey legs.
Yellow legs are also a common trait in native Swedish populations. Finally, though the vast majority of Hedemoras have four toes, the breed’s genetic diversity sometimes yields the odd five-toed individual.
Temperament and Behavior
The Swedish Hedemora is highly recommended for beginners, mostly because of its lovely temperament. These chickens are fearless but easy to handle, making them a safe, charming addition to family farms and homesteads with children. They are known for their calm, docile, and friendly dispositions.
Behaviorally, the Hedemora still has the sharp instincts of a traditional landrace. They are active, self-sufficient, and unrivaled foragers that confidently roam free-range environments to hunt for insects, seeds, and vegetation.
This natural wariness also makes them very good at predator avoidance, something often lost in modern commercial birds.
The breed is also known for its strong mothering instincts, with 30 to 40 percent of hens going broody naturally.
The dense, insulating feathers of a single hen are fiercely dedicated to the task, successfully hatching and raising up to 20 chicks, making them an ideal choice for natural flock expansion.
Egg Production
Hedemora hens are good layers for cold climates, laying 150-200 medium, tinted eggs (50-60g) per year on average. They are so cold hardy that they can lay consistently in winter, using little energy to keep warm.
Since ovulation is light-dependent, keepers can supply supplemental artificial light to create a 14 to 16-hour day in the winter.
Hens ovulate every 24 to 26 hours without needing a rooster. Since the egg-forming process takes roughly 26 hours, laying occurs slightly later each day until the hen eventually skips a day to reset her cycle.
Size And Weight
The Swedish Hedemora is officially classified as a medium-large fowl breed. They are significantly larger than true bantam breeds, but they fall on the smaller end of the spectrum for standard-sized chickens.
However, visual observation of the Hedemora is incredibly deceiving. Because of their extra layer of dense under-down and their profuse, fluffy exterior plumage, the birds appear much heavier, wider, and more powerful than their actual skeletal and muscular mass dictates.
| Sex | Average Weight (Kilograms) | Average Weight (Pounds) |
| Hens (Females) | 1.5 – 2.0 kg | 3.3 – 4.4 lbs |
| Roosters (Males) | 2.0 – 2.5 kg | 4.4 – 5.5 lbs |
Chicken Appearance
Hedemora chickens are a visual spectacle of genetic diversity in a flock. No two birds are alike; each chicken is a unique masterpiece because conservation rules do not allow breeding for standardized uniformity.
The plumage colors within the breed are vast and encompass nearly the entire spectrum of poultry genetics. Common colors include solid black, pure white (or nearly white), and blue (a genetic term for various shades of slate grey).
Other prevalent colors include rich reds, buffs, browns, and wild or wheat-colored variations. It is incredibly common for individual birds to display a beautiful, blended mix of several different colors across their neck, breast, and saddle feathers.
The physical structure of the feathers lends infinite grace to the appearance. Hedemoras have well-developed, deeply cupped saddle feathers on the lower back just before the tail that look and act like a built-in cushion.
The downy undercoat often grows luxuriantly down the thighs of the bird. This abundant thigh feathering partly covers the upper legs and creates a very distinctive silhouette that conservationists and keepers affectionately call the “wide pants” or trouser-wearing look.
Hedemora Rooster Vs. Hens
As with most poultry breeds, the Swedish Hedemora exhibits clear sexual dimorphism, meaning the roosters (males) and hens (females) display distinctly different physical traits as they mature.
Size and Build: The biggest difference is their body mass in general. Roosters are much larger and stockier, generally weighing 1 to 1.5 pounds more than the hens.
Facial Features: Facial features are minimized throughout the breed to prevent frostbite with a definite sex distinction. The hen’s remarkably small comb and wattles sometimes hardly show from her head feathers. The rooster, however, has a single comb of medium size and rather larger wattles. In birds with the fibromelanosis gene, these combs and wattles can be dramatically tinged with black, purple, or blue.
Plumage Differences: Roosters develop highly specialized, elongated feathers as they mature. The hackle feathers (around the neck) and the saddle feathers (draping over the lower back) on a rooster are long and sharply pointed. In sunlight, these feathers often display a brilliant, iridescent metallic sheen, even on dark-colored birds. A hen’s neck and back feathers remain short, broad, and rounded. Additionally, roosters develop long, dramatic, arching sickle feathers in their tail assembly, a feature entirely absent in the compact tails of the hens.
| Feature | Hedemora Rooster | Hedemora Hen |
| Average Weight | 4.4 – 5.5 lbs | 3.3 – 4.4 lbs |
| Comb & Wattles | Medium-sized, stands erect | Very small, minimal frostbite risk |
| Neck/Back Feathers | Long, pointed (hackles/saddles) | Short, rounded, smooth blending |
| Tail Structure | Long, arching sickle feathers | Compact, upright, no sickles |
Raising and Caring for Hedemora Chickens
Caring for Swedish Hedemora chickens require understanding their environmental tolerances. As cold-weather superstars, they easily withstand freezing temperatures that distress other breeds. However, this heavy insulation makes hot weather a dangerous liability.
Hedemoras are very heat-intolerant and don’t do well in warm climates. They should not be raised where summers exceed 100°F (38°C) or they risk fatal heatstroke. In moderate summer regions, keepers offer plenty of fresh water and deep shade.
Winter housing must provide shelter but also good ventilation so that exhaled moisture can escape. Humidity trapped in tight coops settles on combs and freezes, causing frostbite. Having a dry, draft-free, well-ventilated coop is important.
Good nutrition supports egg production and health. High-quality complete layer feed like Purina Flock Strong should be 90% of their diet. Strong calcium systems in formulations mean hard shells and sustained bone density.
Hedemoras are avid foragers and will supplement their diet with insects and greens in the summer. In winter, keepers will often make “winter teas” from dried herbs steeped in warm water to provide an extra boost of nutrition and hydration.
Common Health Issues in Hedemora Chickens
Hedemoras have strong landrace genetics, making them resistant to many common reproductive and respiratory diseases. However, their distinctive feathering makes them susceptible to the extremely annoying Scaly Leg Mite (Knemidocoptes mutans).
These tiny parasites tunnel under the scales of legs and feet, and the waste they produce forces the scales apart, causing severe crusting, pain, and lameness. Feather-legged Swedish Hedemoras are particularly vulnerable, as their feathers create a warm and humid microclimate in which mites thrive and camouflage early signs of infestation.
Treatment requires diligence. Because these contagious mites spread easily in damp runs and on wooden roosting bars, coop bedding must be completely cleaned out and roosts treated with a permethrin-based poultry spray to break the life cycle.
Keepers may choose natural topical and pharmacological treatment methods:
Natural Method:
This natural method is highly effective but requires a multi-day commitment.
- Soak and Clean: Soak legs in warm water with mild soap or disinfectant (such as Hibiscrub) for 10 to 15 minutes to soften tissue. Pat dry with a clean towel, gently exfoliating loose scales without pulling them out to avoid bleeding.
- The Oil Dip: Submerge legs and feet entirely in a mild oil (such as linseed, olive, mineral, or vegetable oil) to seep under the scales and immediately suffocate adult mites.
- The Smothering Barrier: Coat legs thickly with petroleum jelly or A&D ointment to create an airtight barrier that suffocates remaining mites and nits while promoting healing. Repeat this process every other day for 14 days to eradicate newly hatched nits.
The Pharmacological Method:
Veterinary literature recommends off-label use of Ivermectin (0.1 mg per pound of body weight, orally or applied topically on the back of the neck) to kill mites systemically in severe infestations. Repeat in 2 weeks to kill newly hatched nits. There is an unofficial 21-day egg withdrawal period where eggs cannot be eaten.
Hatching and Incubating Eggs
“It’s very rewarding to build out a Hedemora flock. Hens are great mothers and will hatch 10-12 eggs naturally, but many keepers use artificial incubation to grow their flock more predictably.
Successful artificial incubation requires the use of high-quality fertile eggs from healthy, well-nourished breeders.
When purchasing eggs from outside sources, be sure to obtain them from National Poultry Improvement Plan (NPIP)-certified producers, whose flocks have been tested and shown to be free of vertically transmitted contagious diseases.
Hatching eggs should be clean, well-formed, and medium in size. Thin or cracked shells will not hold the needed moisture. Don’t wash or wipe dirty eggs, however, as this removes the protective bloom and pushes bacteria through tiny pores into the shell.
The total incubation period for chicken eggs is 21 days, which is split into two separate phases:
Days 1 – 17 (Development): Maintain the incubator at a temperature of 99.5°F to 100.5°F (37.5°C) and relative humidity of 45% to 55%. Eggs have to be turned 3 to 5 times each day to prevent the embryo from sticking to the inner shell membrane.
Days 18-21 (Lockdown Phase): Stop turning eggs so the chick can orientate itself for hatching. Increase relative humidity to 65-70% to loosen shell membranes and prevent shrink wrapping. Increase the air circulation to provide fresh air and keep the incubator closed to retain the humidity.
| Incubation Stage | Temperature | Relative Humidity | Egg Turning Protocol |
| Days 1 – 17 | 99.5°F – 100.5°F (37.5°C) | 45% – 55% | Turn 3 to 5 times daily |
| Days 18 – 21 (Lockdown) | 99.5°F (37.5°C) | 65% – 70% | STOP TURNING |
FAQs About Swedish Hedemora Chickens
1. Are Hedemora chickens good for beginners?
Of course. Hedemora is a very good choice for novice breeders of poultry. They are easy to handle because they are docile and friendly and calm. And since they are a hardy, self-sufficient landrace breed, they are generally much healthier and less demanding of medical management than delicate commercial hybrids.
2. What color eggs do Swedish Hedemora hens lay?
Hedemora hens lay lovely tinted eggs, ranging in color from off-white and cream to light brown. They are medium-sized eggs, approximately 50 to 60 grams in weight, often with a light speckled pattern.
3. Do hens need a rooster to lay eggs?
No. The biological process of ovulation in a hen is triggered by daylight and hormones, occurring naturally every 24 to 26 hours. A hen will produce eggs consistently regardless of whether a rooster is present. A rooster is only necessary if the goal is to produce fertilized eggs for hatching baby chicks.
4. How well do Hedemora chickens tolerate the summer heat?
They tolerate extreme heat very poorly. The Hedemora is biologically adapted for sub-Arctic Swedish winters. Their incredibly dense down feathers and small facial appendages (which limit heat escape) make them highly susceptible to heatstroke. They should not be raised in regions where summer temperatures consistently reach 100°F (38°C).
5. Are Swedish Hedemoras recognized as a standard breed by the APA?
No. The Swedish Hedemora is a very old landrace fowl, not a standardized show breed. They show much natural variation in feather types, leg feathering, and plumage colors. The Swedish conservation groups specifically dissuade breeding them to a strict visual standard to maintain their historical integrity and rugged health.
6. What is fibromelanosis, and is the meat safe to eat?
Fibromelanosis is an interesting genetic trait that causes hyperpigmentation in many of the Hedemora chickens. This stains their skin, shanks, internal organs, and bones a dark purple-blue or solid black. It does change the appearance of the bird dramatically but has absolutely no negative effect on the flavor, nutritional value, or safety of the meat. The meat can be harvested and eaten normally.
7. Why do some Hedemora chickens look like they are wearing pants?
The breed’s signature “wide pants” look is no accident; it is an evolutionary adaptation. They grow profusely down-filled feathers aggressively down their thighs and sometimes over their shanks to give the legs maximum thermal insulation during freezing weather, creating the lovely illusion of fluffy trousers.
Conclusion: Is This Hedemora Chicken Right for Your Flock
The Hedemora chicken is a great choice for a keeper in a cold northern climate. They have excellent frostbite resistance, great foraging ability, and dependable winter egg production, which are big advantages.
They have calm, friendly personalities and strong maternal instincts as well, making them a sustainable and joyful addition to family farms.
On the other hand, they are not adapted to hot, humid environments, in which their heavy downy insulation presents the deadly danger of heatstroke. Also, those wanting a flock that looks the same will find the breed’s wide genetic diversity from smooth feathers to fluffy wool in a variety of colors—contrary to their wishes.
The Hedemora is, in the end, a living link to agricultural history. In the right hands, this breed will deliver consistent egg production, great companionship, and the deep satisfaction of having preserved one of the world’s most resilient and unique heritage poultry breeds.
