How many eggs do chickens lay?

A productive backyard hen lays about 5–6 eggs per week in her first laying year, which works out to roughly 200–280 eggs per year for popular dual-purpose breeds. Production-bred sex-links (Golden Comet, Red Star, ISA Brown) push 280–320 in year 1; ornamental breeds like Silkies sit at 100–120. The numbers drop predictably with age: year 2 is roughly 80% of peak, year 3 about 65%, year 4+ sporadic.

Per day, per week, per year

The clearest way to think about it is per week. Hens never lay 7 days in a row sustainably — the ovulation cycle is slightly longer than 24 hours, so each egg shifts a little later in the day until the hen skips one and resets the cycle. The math:

Window	Productive hen (peak)	Mature hen (year 2)	Older hen (year 3+)
Per day	0.7–0.85	0.55–0.7	0.3–0.55
Per week	5–6	4–5	2–4
Per year	200–280	160–225	90–180

A flock of 6 productive hens averages 4–5 eggs per day — not 6. Account for that when you size a flock to a household's egg consumption. Most US households use 4–6 eggs per person per week; a 4-person household needs 16–24 eggs/week, which 4–5 productive hens cover comfortably with a small surplus.

By breed class

Breed	Eggs/year (peak)	Class
Leghorn (white)	280–320	Production
Golden Comet / Red Star (sex-link)	280–320	Production hybrid
ISA Brown	300+	Production hybrid
Rhode Island Red	220–280	Heritage / dual-purpose
Plymouth Rock	200–280	Heritage / dual-purpose
Australorp	250–300	Heritage / dual-purpose
Wyandotte	200–240	Heritage / dual-purpose
Buff Orpington	175–220	Heritage / dual-purpose
Easter Egger	200–280	Mixed / colored eggs
Marans	150–200	Heritage / dark eggs
Silkie	100–120	Ornamental (small eggs)
Polish	150–200	Ornamental

These ranges reflect the breed's genetic potential under good management — adequate light, complete layer feed, low stress, predator-secure coop. Real-world backyard production often runs 10–20% under the catalog number because of weather, molt timing, the occasional broody pause, and the specific mix of birds in a small flock. A 220-eggs-per-year breed averaging 180 in your coop is normal, not a problem.

Production breeds vs heritage — the long-term tradeoff

The temptation with hatchery catalogs is to optimize for the year-1 number. A Golden Comet at 320 eggs versus a Plymouth Rock at 230 looks like a clear win. The catalog comparison is misleading for backyard flocks that keep birds for 3+ years.

Production sex-links (Golden Comet, Red Star, ISA Brown, Black Star, Cinnamon Queen) peak hardest in year 1 and decline sharply. Year 3 is often half of year 1. Higher rates of reproductive issues — egg yolk peritonitis, prolapse, calcium-related fragility — by year 4 in this class.
Heritage dual-purpose breeds (Plymouth Rock, Rhode Island Red, Australorp, Wyandotte) lay fewer eggs in year 1 but stretch the curve. A Plymouth Rock at year 4 often lays as much as a sex-link at year 3.
Total eggs over 4 years are often within 10–15% between a top sex-link and a top heritage breed — the volume difference shows up mostly in year 1.

A practical mixed-flock approach: 50% production sex-links for year 1–2 volume, 50% heritage for the long-tail laying contribution and the more durable temperaments. Rotate in 2–3 new pullets every 12–18 months and the flock keeps a steady output without dropping into the year-3 dip.

Sizing a flock to expected eggs

The shortcut that works for most US households:

Household size	Eggs/week needed	Suggested flock
1–2 people	8–12	3 hens
3–4 people	15–24	5–6 hens
5–6 people	25–36	7–9 hens
Sharing/selling surplus	40+	10–12 hens

The flock numbers assume average production breeds and account for winter slowdown, molt pauses, and occasional broody bird dropping out for a few weeks. Use the coop size calculator to verify the housing footprint matches the flock size.

What the catalogs don't advertise

Year-1 production assumes ideal conditions. 14+ hours of light, complete layer feed, no stress events, no extreme heat or cold. Real backyard conditions usually knock 10–20% off the published number.
Most breeds slow or stop in molt. 8–12 weeks of zero or near-zero production every fall, even with supplemental light. The catalog year-1 number rarely accounts for this.
Pullets in their first 4–8 weeks lay smaller, irregular eggs. Don't count point-of-lay weeks as full production weeks — they aren't.
Hatchery sex-link “commercial” numbers are from controlled-environment houses — climate-controlled barns at 22°C, 16h light, full ration, replaced annually. Backyard conditions rarely match.

Frequently asked

How many eggs does a chicken lay per day?

Backyard hens at peak production lay roughly one egg every 24–28 hours — call it 5–6 eggs per week, or 0.7–0.85 per day. Hens never lay 7 days a week sustainably; the ovulation cycle is slightly longer than 24 hours, so each egg shifts a little later in the day until the hen 'skips' a day and resets. A flock of 6 productive hens at peak averages 4–5 eggs per day, not 6.

How many eggs per year for a typical backyard hen?

200–280 eggs in the peak laying year (roughly age 6–18 months) for most popular backyard breeds. Production-bred sex-links (Golden Comet, Red Star, ISA Brown) push 280–320; heritage breeds (Wyandotte, Buff Orpington, Plymouth Rock) sit at 180–250; ornamental and bantam breeds (Silkie, Polish) lay 80–150. By year 2, expect ~80% of peak; by year 3, ~65%; by year 4+, sporadic.

Which backyard breed lays the most eggs?

Leghorns and the modern sex-link production hybrids (Golden Comet, Red Star, ISA Brown, Black Star) are the highest layers — 280–320 eggs in their peak year. The tradeoff is that production sex-links drop sharply after year 2 and have higher rates of reproductive issues by year 3. For total eggs over a 4-year span, heritage breeds like Plymouth Rock, Rhode Island Red, and Australorp often equal or exceed sex-links because their decline is gentler.

Why do chickens lay fewer eggs in winter?

Daylight, mostly. Hens need ~14 hours of daylight to maintain laying and stop or slow below ~12 hours. Late fall through early spring — roughly October through February in most of North America — falls below the threshold. Cold itself doesn't stop laying directly; in fact, hens with adequate insulation and feed lay fine in below-freezing temperatures as long as photoperiod is maintained. Add supplemental light if you want winter eggs, or accept the natural pause.

Do hens lay year-round?

Not naturally. Backyard hens follow the seasonal photoperiod — production peaks in spring and summer, drops in fall, often pauses through winter, then resumes in early spring. The flock will also pause for 8–12 weeks of annual molt, usually in late summer or fall. Adding supplemental light extends the laying season but doesn't eliminate the molt pause. Commercial laying operations get year-round production by combining controlled light, controlled temperature, and replacing the flock every 12–18 months — none of which is the backyard model.

How long do hens keep laying?

Most hens lay productively for 3–4 years, then slow to sporadic laying for several more years. Lifespan is breed-dependent: heritage breeds can live 8–12 years and lay occasionally well into year 5–6. Production sex-links often slow dramatically by year 3 and have higher mortality from reproductive issues by year 4–5. The economic-laying window (where eggs roughly cover feed cost) is typically year 1 and year 2.

Per-breed peak-year ranges synthesize hatchery catalog standards (Murray McMurray, Meyer Hatchery, Cackle Hatchery 2026 catalogs) and university extension breed-comparison data; backyard production typically runs 10–20% below catalog ranges.
