How many laying hens do I need?

Short answer

2–3 per person

Two to three hens per person covers fresh eating for most households — so 8 to 12 for a family of four if you eat eggs most days and want enough coming through winter. Eat eggs on weekends? Four to six is plenty. Bake often and share with neighbors? Go to three per person and don't apologize.

The arithmetic, so you can check it

A hen in her first laying year gives you 200–240 eggs — University of Florida IFAS's figure for a backyard flock, or 17–20 dozen.
A family of four eating a dozen a week needs 624 eggs a year.
624 ÷ 220 = 2.8 hens.
Round up to three per person. That 220 assumes a good year with no gaps, and you will have gaps.

Where the experts disagree — and it's a wide gap

Ask six extension services how many eggs a hen lays and you'll get answers from 182 to 312 a year.

Oklahoma State (budget assumption): ~182 — "an egg every other day"
University of Florida IFAS: 200–240
Oregon State (commercial Leghorn): ~265
Mississippi State (laying breeds): 250–300
University of Minnesota: ~312 — "roughly six eggs each week"

This isn't sloppiness — it's two different birds. The 250–300 figures describe commercial-strain layers under supplemental light on a controlled ration. The 182–240 figures describe what a backyard flock of dual-purpose birds actually produces across a real year, with molt, winter, and a rooster's worth of chaos. University of New Hampshire's side-by-side is the cleanest illustration: a White Leghorn gives 250–300, a Barred Rock 200–280. Mississippi State explains the mechanism plainly — "egg production and growth are negatively correlated." Birds bred to put on meat lay fewer eggs. You cannot have both.

Plan on 200–240 unless you're buying production hybrids and lighting the coop.

What changes your number

Breed. Sex-links and Leghorns out-lay heritage dual-purpose birds by 20–30%. You're trading eggs for meat, hardiness, and broodiness.
Winter light. Hens need about 14 hours of daylight to keep laying — the modal recommendation across Oregon State, Penn State, UF/IFAS, UNH, and eXtension. Without supplemental light, expect a real winter dip.
Molt. Every hen stops laying to regrow feathers. Mississippi State puts the range at 6 weeks for a fast late molter to 4–6 months for a slow early one — and notes the fast molters are your better layers.
Age. UF/IFAS tracks production peaking near 90% about 6–8 weeks after she starts, easing to 65% by the end of her first 12 months of lay. Most flocks lay well for 3–4 years (Wisconsin).
Point of lay. Pullets start at 18–22 weeks. Buy chicks in April, expect eggs in September.

A number we won't give you

One number we won't give you: how much production drops in year two versus year one. You'll see "about 80% of the previous year" repeated everywhere online. We went looking for the source and there isn't one — no land-grant extension publishes that figure. What's real is the within-cycle curve above and a 3–4 year useful life. When we don't have a sourced number, we'll tell you.

How much space

	Coop (indoor)	Run
Bantams	1 sq ft	4 sq ft
Laying hens	1.5–4 sq ft	8–10 sq ft
Large fowl	2–4 sq ft	10 sq ft

That coop range is not a typo, and it's the second place the sources split hard. Penn State says 1.5 sq ft; UF/IFAS, Minnesota, New Hampshire, and eXtension say 3–4. eXtension is refreshingly honest about why: "there is very little peer-reviewed research looking at the space allowances for backyard poultry." Practical read: build to 3 sq ft per bird if they're shut in through hard winters, 2 if they range daily most of the year. Nobody ever regretted a bigger coop. Also from Penn State: 6 inches of roost per bird (4 for bantams), 3 inches of feeder space, and one 12×12 nest box per 4–5 hens — with two boxes minimum even for a flock of four, because hens queue for the box they've decided is correct.

What it costs to keep them

A laying hen eats about a quarter pound of feed a day (Alabama Extension, Oklahoma State) — 90 to 100 pounds a year, which is University of New Hampshire's directly stated figure and lines up with the daily math. Ten hens go through a 50-lb bag in about 20 days (Alabama Extension). University of Maryland's small-flock budget works out to 4–5 lbs of feed per dozen eggs, the lower end if they have pasture.

What to do with the surplus

Twelve hens in June will bury you. Eggs keep for weeks unwashed and refrigerated — and the storage question has its own genuine disagreement between USDA guidance and long homestead practice.

Then stop planning from averages

Every number on this page is an average from someone else's flock. Your Buff Orpingtons, in your climate, on your feed, will do something slightly different — and after one season of records you'll know exactly what, instead of estimating from a table.
