Chicken Egg Production Calculator
Estimates how many eggs your flock will lay per week, month, and year from its size and breed.

A young hen's first laying year is her most productive. Expect output to dip during molts and short winter days, and to fall roughly 10–20% a year as hens age.
What a typical flock produces
Six Rhode Island Red hens in their first laying year produce roughly 29–35 eggs a week — about125–150 a month, or 1500–1800 a year. Pick your breed and flock size above to see your own numbers.
How this works
Each breed has a typical first-year laying rate — a Leghorn or ISA Brown pushes 280–320 eggs, a dual-purpose Rhode Island Red 250–300, and heavy or ornamental breeds like Brahmas and Silkies far fewer. The calculator multiplies that rate by your flock size, then divides by 52 for the weekly figure and 12 for the monthly one. It shows a range rather than a single number, because no hen lays the same count two years running.
The honest caveat is that these are good-conditions, first-year figures — a ceiling, not an average. Three things pull real output below the number: daylight (laying slows or stops below about 12 hours of light, which is why winter eggs are scarce), the annual molt(hens stop laying for weeks while they regrow feathers, usually in fall), and age(production falls roughly 10–20% each year after the second). A flock's real annual total often lands 20–30% under the peak-rate math once you account for all three.
A worked example
Say you keep 10 Australorps, rated around 250–300 eggs a year. The calculator gives 2,500–3,000 eggs a year, or roughly 48–58 a week — call it four dozen a week at peak. In practice you'll see close to that through spring and summer, a sharp dip during the fall molt, and a quiet winter unless you add supplemental light. Plan your egg-selling or baking around the peak, not the yearly total divided by 52.
Want steadier year-round eggs? Keep a mix of breeds and ages, add a couple of pullets every year or two, and choose at least one winter-hardy layer like an Australorp, Sussex, or Chantecler. A flock that's all one age will all molt and slow down at once.
Frequently asked questions
- How many eggs do 6 chickens lay per week?
- It depends on the breed. Six good layers like Rhode Island Reds or ISA Browns produce roughly 30–40 eggs a week at their peak, while six ornamental or heavy breeds might give 15–25. Multiply a hen's yearly output by your flock size and divide by 52 for the weekly number — or just use the calculator above.
- Do chickens lay an egg every day?
- The best layers come close — a top hen lays about 5–6 eggs a week, not a perfect 7, because her laying cycle runs slightly longer than 24 hours. Most backyard breeds lay 3–5 a week. A hen physically cannot lay more than one egg per day.
- Why has my flock stopped laying?
- The usual suspects are short winter days (laying is driven by daylight, ideally 14+ hours), the annual molt when hens redirect energy into new feathers, age, stress, a broody hen sitting tight, or a hidden nest you haven't found. Cold itself doesn't stop laying, but the short days that come with it do.
- How long do hens keep laying?
- Hens lay most heavily in their first two years, then production tapers roughly 10–20% each year. Many keep laying at a reduced rate for 5–7 years or more. If eggs are your goal, plan to add a few new pullets to the flock every year or two to keep overall output up.
- Are the numbers in this calculator guaranteed?
- No — they're typical first-year figures for each breed and should be read as a range, not a promise. Real output swings with daylight, feed quality, weather, health, and the individual hen. Treat the yearly figure as a good-conditions ceiling and expect real life to land somewhat below it.
