What drives egg production
Three factors explain almost all the variation between "my hens lay daily" and "why am I buying eggs again?":
- Breed. Production hybrids were bred to lay 300+ eggs in their first year; ornamental breeds like Silkies lay a third of that. The breed baseline is the ceiling everything else discounts from.
- Age. Hens lay best in their first laying year. Expect roughly 15% fewer eggs each year after — by year four, production is about half of peak. (Egg size goes the other way: older hens lay fewer but larger eggs.)
- Daylight. Laying is triggered by light — hens need ~14 hours of daylight for full production. That's why production crashes in fall (molt + shrinking days) and recovers in spring. Adding a simple coop light on a timer in winter restores most production, at the cost of giving the hens no seasonal rest.
Typical first-year production by breed
| Breed | Eggs / year | Eggs / week | Egg color |
|---|---|---|---|
| ISA Brown / Golden Comet | 300–330 | 5.8–6.3 | Brown |
| White Leghorn | 260–300 | 5.0–5.8 | White |
| Rhode Island Red | 240–280 | 4.6–5.4 | Brown |
| Australorp | 240–260 | 4.6–5.0 | Brown |
| Plymouth Rock / Sussex | 200–240 | 3.8–4.6 | Brown / tinted |
| Easter Egger | 180–220 | 3.5–4.2 | Blue / green |
| Orpington / Brahma | 160–200 | 3.1–3.8 | Brown |
| Marans / Welsummer | 160–200 | 3.1–3.8 | Dark brown |
| Silkie | 100–120 | 1.9–2.3 | Cream / tinted |
My hens are laying less than the estimate — why?
Work through this checklist in order; it catches the cause for most flocks:
- Molt. Once a year (usually fall), hens replace feathers and stop laying for 6–12 weeks. Completely normal.
- Hidden nests. Free-ranging hens are excellent at laying under sheds and in tall grass. Lock the flock in the run for a few days — if "production" jumps, you've been robbed by your own hens.
- Stress or changes. A new predator visiting at night, a move, new flock members, or extreme heat all pause laying for days to weeks.
- Protein shortfall. Laying needs a complete 16–18% protein feed. Heavy treat feeding (scratch is only ~9% protein) measurably cuts production.
- Egg eating or theft. Snakes, rats, and occasionally the hens themselves. Shell fragments in the nest box are the giveaway.
- Age. If the flock is 3+ years old, the estimate above is the answer — that's just where they are.
FAQ
Do hens lay an egg every day?
No breed truly lays 365 days a year. An egg takes about 25–26 hours to form, so even a top hybrid at peak "skips" progressively later each day and misses days regularly. Six eggs a week from one hen is elite production.
Do I need a rooster to get eggs?
No. Hens lay on their own cycle regardless. A rooster is only needed if you want fertile eggs for hatching — in which case, see our Incubation Calculator.
When do pullets start laying?
Most breeds reach point-of-lay at 18–22 weeks; production hybrids can start at 17 weeks, while heavy and ornamental breeds may take 24–28 weeks. First eggs are small and irregular for a few weeks — that's normal.
Is winter lighting bad for hens?
It's a trade-off. A timer bringing total light to ~14 hours keeps hens laying through winter, but the winter pause is a natural rest. Many keepers light the coop for year one or two, then let older hens rest. If you do supplement, add light in the morning so dusk comes naturally and hens can roost.
