Pick what kind of chicken she is and, if you like, how old she is now. You get the lifespan each source publishes for that kind of bird, drawn as a range and never averaged. Her age is marked against each one, along with where she is in her laying years.
Backyard hen
3 to 7 years — or 6 to 8: two published answers
Her laying years
What changes it
A hen that is suddenly unwell is a question for a vet, not for a chart.
Lifespan figures checked 2026-09-26: UW Extension, Meyer Hatchery, The Livestock Conservancy; UMN Extension checked 2026-09-22.
Quick answer: a backyard hen usually lives 3 to 7 years by Meyer Hatchery’s count, or 6 to 8 by the University of Wisconsin’s. The two don’t agree, and this page prints both. What kind of bird she is moves it more than anything. Meyer puts a dual-purpose breed like a Barred Rock at 5 to 8 years, says some heritage birds reach 8 to 10 and landrace breeds often live over 10. The production layers — sex-links bred for high egg production — get 2 to 3 years in a commercial flock, “as laying large numbers of eggs can tax their bodies.” Pick her kind above and put in her age, and the chart shows where she stands.
Why the egg machines don’t last as long
This is the part the catalogues go quiet on. A hen bred to lay close to 300 eggs a year is spending a lot of herself on it. Meyer Hatchery says it plainly about its own production layers: commercial egg-laying breeds like the Black Sex Link and Golden Buff “are known for high egg production but have relatively short lifespans of around 2-3 years in a commercial setting.” A dual-purpose hen laying fewer eggs “often live slightly longer than hybrids bred for laying.”
Two things are worth knowing before you write your sex-links off. That 2 to 3 years is a commercial figure, from barns where hens are kept for eggs and nothing else. Meyer adds that “In a backyard setting with things like more activity and laying breaks over winter it is possible for these breeds to live and lay longer.” Nobody publishes a backyard number for them, so this chart doesn’t invent one.
How long do they lay?
Not as long as they live. The University of Minnesota: “Hens begin laying at around six months of age and can continue for five to 10 years, with peak production occurring in the first two years.” Wisconsin puts the working life shorter: “most flocks will produce eggs for 3-4 years,” and “The level of egg production, egg size, and shell quality decrease each year.” Meyer describes the same slide: “By their third year, egg production slows, with fewer eggs each week and a gradual decline in egg size and shell quality.”
So a hen will spend a good part of her life laying less than she used to, or not at all. Wisconsin’s advice to keep a small flock producing is to “plan to retire old hens and add young hens (pullets) every 2-3 years.” Retire is the word they use, and plenty of us mean it literally. If you want to see how many eggs an older flock will actually give you, the egg production calculator does that from each hen’s breed and age.
Heritage birds and the long road
The Livestock Conservancy, which keeps the old breeds going, writes a long life into its definition of a heritage chicken. It says the bird “must have the genetic ability to live a long, vigorous life,” and “Breeding hens should be productive for 5-7 years and roosters for 3-5 years.” That’s a standard, not a promise, but it’s why a Brahma or an Orpington in a safe coop tends to outlast a hybrid.
What decides how long yours live
Breed sets the range. What happens inside it is mostly up to you, and mostly about predators. Meyer: “Protection from predators and a clean, spacious coop and run play a big role in a chicken’s health and longevity.” With ideal care, it says, hens “can reach 10 years or even older.” The coop size calculator is a good place to start on the spacious part.
