How Long Do Chickens Live and Lay Eggs?
Understanding the lifespan and productive years of a laying hen helps you plan your flock, set realistic expectations, and make smart decisions about when to add new birds. Here's what you need to know.
How Long Do Chickens Live?
The average backyard chicken lives 5–8 years, though some hens live to 10–12 years with good care. Lifespan varies significantly by breed:
- Hybrid layers (like Golden Comets) — Typically 4–6 years. Bred for high production, which can shorten overall lifespan compared to heritage breeds.
- Heritage breeds (Rhode Island Red, Plymouth Rock, etc.) — Often 6–8+ years.
- Bantam breeds — Can live 8–10+ years.
The most common causes of early death in backyard flocks are predator attacks, disease, and reproductive issues (particularly in high-production hybrid hens).
When Do Hens Start Laying?
Most laying breeds begin producing eggs between 16 and 22 weeks of age, depending on breed and season. Golden Comets are early starters — typically laying by 16–18 weeks. Heritage breeds often take 20–24 weeks or longer.
Our point-of-lay pullets are at or very near this threshold when you pick them up, meaning eggs within days to weeks of bringing them home.
Egg Production Over a Hen's Lifetime
Year 1 (Point of Lay to 18 Months)
Peak production. A Golden Comet in her first laying year will produce 250–320 eggs. Eggs are consistent in size and shell quality. This is the most productive period of a hen's life.
Year 2
Production remains strong but begins to taper slightly — typically 200–260 eggs for a Golden Comet. Egg size often increases. Most flock owners find year 2 hens still highly productive.
Year 3
A noticeable decline begins. Expect 150–200 eggs per year. Shell quality may start to vary. Some hens remain strong layers; others drop off more significantly.
Year 4 and Beyond
Production drops to roughly 50–60% of peak or less. Many hens continue laying sporadically for years, but not at a rate that makes economic sense for a production-focused flock. Heritage breeds tend to hold production better in later years than hybrids.
When Do Hens Stop Laying Entirely?
Most hens don't stop laying abruptly — production gradually declines until eggs become infrequent. A hen may lay her last egg at age 4, or continue sporadically until age 7 or 8. There's no precise cutoff.
Factors that accelerate decline include poor nutrition, chronic stress, disease history, and lack of supplemental lighting in winter.
Planning Your Flock for Consistent Production
If consistent egg supply is your goal, the most effective strategy is flock rotation: adding a new group of point-of-lay pullets every 2–3 years to maintain a mix of ages and production levels. This keeps your flock producing at a high rate year-round without a complete production gap.
Many small egg operations run two age groups simultaneously — one in peak production, one in year 2 — so there's always a strong layer in the flock.
Pro tip: Spring is the ideal time to add new pullets. They'll reach peak production by summer and carry strong output through their first winter — exactly when your older hens are slowing down.
