Quick answer: Hens usually stop laying because of shortening daylight, molting, age, broodiness or a protein shortfall — in that order. If it happened in autumn, it is almost certainly daylight or a molt and it will resolve on its own. If it happened suddenly in spring or summer, look at stress, parasites, water supply, or a hidden nest you have not found yet.
Diagnose it in 30 seconds
Before you buy supplements or panic, run through this. The season and the speed of the drop tell you almost everything.
| What you are seeing | Most likely cause | Fix |
|---|---|---|
| Gradual slowdown in autumn | Shortening daylight | Wait, or add light |
| Feathers everywhere, bare patches | Molt | Raise protein, wait 8-12 weeks |
| Hen flat in the nest box, puffed up, growling | Broody | Break the broodiness |
| Hen is 3+ years old, slow decline over seasons | Age | Nothing; normal |
| Whole flock stopped within days | Stress, predator, or water outage | Investigate the environment |
| Soft, thin or shell-less eggs first | Calcium shortfall | Free-choice oyster shell |
| Pale comb, weight loss, hunched | Illness or parasites | Inspect the bird, treat |
| Hens look and act completely normal | Hidden nest or egg eating | Confine to run for 3 days |
1. Daylight has dropped below 14 hours
This is the number one reason, and it catches every first-year keeper. Egg production is triggered by light hitting a photoreceptor in the hen’s brain, not by temperature. Hens need roughly 14 hours of light per day to lay consistently.
From late summer onwards, daylight shortens and laying tails off. By December in most of the northern hemisphere you are down to 9 or 10 hours and many flocks stop entirely. It picks back up in late January and February as the days lengthen, often before the weather improves at all.
You can override it with a timer and a low-wattage bulb, adding light in the morning rather than the evening so birds are not plunged into sudden darkness away from the roost. But think about whether you want to. A natural winter rest lets the reproductive system recover, and flocks that are lit year-round tend to burn out sooner, which shows up directly in how long chickens live. Fewer eggs in January often means more years of eggs overall.
2. She is molting
A molt is unmistakable once you have seen one. Feathers all over the run, patchy bald spots, a miserable-looking bird, and zero eggs.
Most hens molt annually in autumn, starting around 18 months old, and it takes 8 to 12 weeks. Feathers are about 85% protein, and regrowing an entire coat is metabolically expensive, so the body shuts down egg production to fund it. There is no way to have both at once.
What helps is protein. Move the flock onto a 20-22% feed, or a game bird ration, for the duration of the molt. Cut back on scratch grain, which is only 8% protein and actively works against her. High-protein treats like mealworms, scrambled egg, sunflower seeds and cooked meat are genuinely useful here.
What does not help is handling her. Emerging pin feathers have a blood supply and are painful, so a molting hen who dislikes being picked up is not being difficult.
3. She is simply getting older
Hens do not lay forever. Production peaks in the first laying year and drops roughly 15-20% every year after.
| Age | Eggs per year | Share of peak |
|---|---|---|
| Year 1 | 250-300 | 100% |
| Year 2 | 200-250 | ~80% |
| Year 3 | 150-200 | ~65% |
| Year 4 | 100-150 | ~50% |
| Year 5+ | 0-100 | Occasional |
Hybrid layers such as ISA Browns and Golden Comets front-load almost everything into years one and two, then fall off a cliff. Heritage breeds lay less at their peak but hold production far longer. If a steady supply matters more to you than a spectacular first year, that trade-off is covered in our comparison of the best egg-laying chicken breeds.
A useful physical check: a hen in lay has a bright red comb and a wide, moist vent you can fit two or three fingers between. A retired hen has a pale, shrunken comb and a tight, dry vent.
4. She has gone broody
A broody hen decides she is hatching chicks, sits in the nest box permanently, puffs up and growls when you approach, and stops laying completely for 21 days or more.
Some breeds do this constantly, particularly Silkies, Orpingtons and Cochins, which we list in full under the broodiest chicken breeds. If you have no rooster and no fertile eggs, she is sitting for nothing and losing condition doing it.
To break it, remove her from the nest repeatedly, block the box off, and if that fails put her in a wire-floored crate with food and water for two or three days. Air circulating under her drops her body temperature and resets the hormone cycle. She will usually resume laying within a couple of weeks.
5. Not enough protein
An egg is roughly 6 grams of protein, produced almost daily. A laying hen needs feed at 16-18% protein to sustain that.
The most common way keepers accidentally cause a laying stop is generosity. Scratch grain, bread, vegetable scraps and mealworms are all fine in moderation, but they dilute the ration. A flock filling up on treats is eating a 10% protein diet whether the bag says 17% or not.
Hold the line at 90% complete feed, 10% everything else. If laying dropped and nothing else fits, look honestly at how much scratch is going into the run. Our guides to what chickens eat and what not to feed chickens cover the balance in detail.
6. Not enough calcium
Calcium problems announce themselves before laying stops. You get soft-shelled eggs, thin shells that crack in the box, or shell-less eggs that look like a membrane sac. Then production halts.
Each egg takes about 2 grams of calcium. Layer feed supplies a baseline, but heavy layers and older hens need more. Offer crushed oyster shell in a separate dish, never mixed into feed, so birds that need it take it and roosters and non-layers do not. Crushed, baked eggshell works too.
Vitamin D3 matters as much as calcium, because without it the calcium is not absorbed. Birds with outdoor access get plenty. Birds shut in a dim coop through winter may not.
7. Stress
Chickens are prey animals, and a stressed hen stops laying within a day. Common triggers, roughly in order of how often they are the culprit:
- A predator scare. Even a failed attempt, or a fox circling at night, can stop a flock for a week.
- New birds introduced. Re-establishing the pecking order suppresses laying in everyone for one to three weeks.
- Moving house or coop. Expect two weeks off.
- A dog, cat or child harassing the run.
- Overcrowding. Chronic, and often invisible until you count. Check the real figures in how much space chickens need.
- Loud construction or sustained noise nearby.
- Running out of water, even for a few hours. Eggs are about 74% water. A hot day with an empty waterer will stop a flock cold.
If the whole flock stopped at once and it is not autumn, work through this list first. A synchronised stop is an environmental event, not a coincidence of individual problems.
8. Heat or cold extremes
Chickens handle cold far better than heat. Below freezing, a healthy well-feathered hen keeps laying, and the cold-hardy breeds barely notice. Production dips in deep winter mostly because of daylight, not temperature.
Heat is the real problem. Above roughly 85°F (29°C) hens eat less, and above 95°F (35°C) laying often stops entirely, along with a rise in thin shells because panting disrupts the acid balance needed for shell formation. Shade, cool water, frozen treats and ventilation all help, and picking heat-tolerant breeds helps more if you are in a hot climate.
9. Illness or parasites
A hen who has stopped laying and looks unwell is a different situation from one who has simply gone off lay. Warning signs: pale or shrivelled comb, weight loss, hunched posture, ruffled feathers, laboured breathing, unusual droppings, or sitting apart from the flock.
The three common culprits are mites and lice, intestinal worms, and respiratory infection. Check for mites after dark around the vent and the base of the tail feathers, where they cluster. A heavy mite load drains a hen enough to stop laying entirely and can kill her within weeks.
Also worth knowing: egg binding is an emergency. A hen straining, walking penguin-style, tail pumping, sitting fluffed and not passing an egg needs help within hours. Clinical guidance is in the Merck Veterinary Manual, and general flock health resources are at Poultry Extension.
The one everyone misses: hidden nests
Before concluding your hens have stopped, make sure they have not just relocated. This is genuinely common and slightly embarrassing when you find it.
Free-ranging hens will abandon a nest box for a spot under a hedge, behind a shed, inside a woodpile or in long grass, and they are good at it. Hens can also clear a low fence to reach somewhere better, which surprises people who assume chickens do not fly. They do, and how far chickens can fly is further than most keepers expect.
The test: confine the flock to the coop and run for three full days. If eggs appear, they were never not laying. Then make the nest boxes more appealing than the alternatives, one box per 3-4 hens, dim, private and at the right height. Our guide to chicken nesting boxes covers the setup that keeps hens using them.
The other possibility is egg eating. Look for shell fragments, yolk smears in the bedding or a suspiciously clean-beaked hen hanging around the boxes. Collect eggs more often, darken the boxes and fix any soft-shell problem, because a cracked egg is usually how the habit starts.
Frequently asked questions
Why did my chickens suddenly stop laying eggs?
A sudden, flock-wide stop points to an environmental cause: a predator scare, new birds, a move, extreme heat, or a water supply that ran out. A gradual autumn decline is daylight or a molt instead.
How long do chickens stop laying in winter?
Typically 2 to 4 months, roughly November through February in the northern hemisphere, resuming as daylight passes about 14 hours a day. Adding supplemental morning light shortens the break but may shorten the hen’s productive life.
Will a hen start laying again after molting?
Yes. Laying resumes once the new feathers are grown, generally 8 to 12 weeks after the molt begins, and eggs are often larger and better-shelled afterwards.
Do chickens stop laying when it is too hot?
Yes. Above about 85°F hens eat less and lay less, and above 95°F many stop entirely. Shell quality suffers too, because panting disrupts the acid balance needed to form a shell.
At what age do chickens stop laying eggs?
Most hens lay usefully for 3 to 4 years, with a steady 15-20% annual decline. Some heritage hens still produce occasional eggs at six or seven years old.
Can stress stop chickens from laying?
Absolutely, and quickly. A predator scare, flock introductions, a house move, a loose dog or a few hours without water will all stop a hen laying within a day, usually for one to three weeks.
Do chickens need a rooster to lay eggs?
No. Hens lay whether or not a rooster is present. A rooster only determines whether the eggs are fertile.

Go deeper on the big two: the autumn shutdown is usually molting, and a quiet drain on laying is often mites. And no, a rooster is not required for hens to lay.
