How Long Do Chickens Live? (Average + Lifespan by Breed)
Every backyard flock has one. The old hen who stopped laying a season or two ago, moves a little slower to the feeder, and still somehow runs the pecking order from the top. She is the one that makes you wonder how many more springs she has in her, and whether you are doing right by her.
How long chickens live depends a lot on the bird and a lot on you. A hardy backyard hen with a safe coop and decent food often reaches 8 to 10 years, and some pass 12. A production hybrid bred to lay 300 eggs a year may burn out at 3 to 5. And a meat bird raised the modern way would not last a year if it were kept. The same word, chicken, covers a wide range of lifespans.
This guide gives you the straight numbers: the average lifespan, a breakdown by breed, how long hens keep laying versus how long they live, and the handful of things that actually decide whether your birds make it to old age.
How Long Do Chickens Live on Average?
Most backyard chickens live 5 to 10 years, with 6 to 8 being typical for a well-kept hen. With a predator-proof coop, good feed, and a bit of luck, heritage breeds regularly reach 8 to 12 years, and the occasional bird lives longer. The oldest chicken on record, a hen named Muffy, lived to 22, but that is the rare exception, not the goal. The figure most keepers should plan around is roughly 8 years for a healthy backyard hen.
The single biggest reason real-world lifespans fall short of that is not old age. It is predators and preventable illness, both of which you have more control over than you might think.
Chicken Lifespan by Breed
Breed is the biggest built-in factor. As a rule, slower-growing heritage and dual-purpose breeds live the longest, while high-output laying hybrids and fast-growing meat birds live the shortest, because their bodies are doing far more work. Bantams and ornamental breeds land in the middle. The ranges below assume good care and a safe coop.
| Breed | Type | Typical lifespan (with good care) |
|---|---|---|
| Buff Orpington | Heritage / dual-purpose | 8–10 years |
| Plymouth / Barred Rock | Heritage / dual-purpose | 8–10 years |
| Australorp | Heritage / dual-purpose | 8–10 years |
| Wyandotte | Heritage / dual-purpose | 8–12 years |
| Easter Egger / Ameraucana | Layer | 7–10 years |
| Rhode Island Red | Dual-purpose layer | 6–8 years |
| Silkie | Bantam / ornamental | 7–9 years |
| Brahma | Heritage / large | 5–8 years |
| Leghorn | Production layer | 4–7 years |
| ISA Brown / Golden Comet | Production hybrid | 3–5 years |
| Cornish Cross (broiler) | Meat bird | Under 1 year if not processed |
If long life is a priority, the calm, hardy heritage breeds in the best chicken breeds for beginners tend to be the safest bets. If you choose a production hybrid for the egg numbers, know that you are trading some years for output.
How Long Do Hens Lay Eggs vs. How Long Do They Live?
These are two different timelines, and confusing them is common. A hen usually starts laying around 5 to 6 months old, lays most heavily for her first 2 to 3 years, then slows down a little each year while she keeps living for many more. So a 7-year-old hen may only lay a handful of eggs a week, or stop over winter, yet still be a healthy member of the flock.
Production hybrids like ISA Browns are the clearest example. They are bred to pour out eggs early, which is why the best egg-laying chickens for sheer numbers are often the ones with shorter lives. Heritage hens lay fewer eggs per year but spread that laying, and their lives, over a longer span. If you want eggs and longevity, a dual-purpose heritage breed is the balanced choice.
How Long Do Meat Chickens Live?
Meat breeds are the short end of the scale by design. A Cornish Cross broiler grows so fast that it reaches processing weight in 6 to 9 weeks, and if kept past that, the same fast growth that makes it efficient causes heart and leg problems, so few live beyond a year. Slower heritage meat breeds and dual-purpose birds live much longer because their growth is not pushed. If you are raising birds for meat, lifespan is not the metric. If you are keeping a pet or layer, avoid the fast broiler types.
What Affects How Long Chickens Live
Genetics set the ceiling, but day-to-day care decides whether a bird reaches it. Four things matter most.
- Predators. This is the number one killer of backyard chickens, full stop. Raccoons, hawks, foxes, dogs, and weasels end far more chickens than old age does. A secure coop is the biggest lifespan lever you control.
- Disease and parasites. Respiratory infections, worms, mites, and illnesses like coccidiosis shorten lives quietly. Clean water, dry bedding, and quick treatment make a real difference.
- Diet. A complete, age-appropriate feed keeps the immune system and organs working. Cheap or unbalanced chicken feed and too many treats lead to fatty liver and other problems over time.
- Genetics and laying load. The harder a hen’s body works to lay, the more wear it takes. High-output hybrids simply have shorter lifespans than slower heritage birds.
How to Help Your Chickens Live Longer
You cannot change a bird’s breed, but you can move it toward the top of its range. Start with the coop: a truly predator-proof chicken coop with hardware cloth instead of chicken wire, a secure door, and a covered run removes the most common cause of early death. From there, give each bird enough space, keep the bedding dry, provide clean water daily, and feed a complete ration with treats kept to a small share of the diet.
Stay ahead of health problems by checking birds regularly for mites and lice, deworming as your climate requires, and isolating any sick hen quickly. The Merck Veterinary Manual is a reliable reference when something looks wrong. None of this is complicated, and together it is the difference between a hen that lasts 3 years and one that lasts 10.

Frequently Asked Questions About Chicken Lifespan
How long do backyard chickens live as pets?
Kept as pets, with a safe coop and good care, backyard chickens commonly live 8 to 10 years, and hardy heritage breeds can reach 12 or more. Pet chickens often outlive working flock hens simply because they are protected from predators and not pushed to lay at maximum output.
Do chickens die of old age?
Some do, but most backyard chickens die earlier from predators or illness rather than true old age. A hen that makes it past her laying years in a secure, well-managed flock can gradually slow down and pass of age-related causes, often somewhere between 8 and 12 years.
How long do laying hens live?
Laying hens live as long as any other hen of their breed, usually 5 to 10 years, but they only lay heavily for the first 2 to 3 years. Production hybrids bred for high output tend to have shorter lives, around 3 to 5 years, than slower heritage layers.
Which chicken breeds live the longest?
Hardy heritage and dual-purpose breeds live longest: Orpingtons, Plymouth Rocks, Australorps, Wyandottes, and similar birds often reach 8 to 12 years. Production hybrids and fast-growing meat breeds have the shortest lifespans.
Do roosters live as long as hens?
Roosters live about as long as hens of the same breed, roughly 5 to 8 years on average, sometimes longer. Because they do not lay eggs, they avoid the reproductive wear that shortens some high-output hens, though they may face more risk defending the flock from predators.
The Bottom Line
Most chickens live 5 to 10 years, and a well-cared-for backyard hen of a hardy breed will often reach 8 or beyond. The number on the calendar is set partly by breed, but mostly by the basics: a predator-proof coop, clean conditions, good feed, and quick attention when something is wrong. Get those right and your old matriarch will likely keep ruling the run for years longer than you would guess.
