Quick Answer: A hen that stops laying is usually dealing with one of eight things: an annual molt, insufficient daylight hours, age-related decline, stress (heat, predators, a new flock member), broodiness, illness, poor nutrition, or a hidden nest you haven’t found yet. Per Virginia Tech Cooperative Extension, hens need roughly 14 hours of daylight to keep laying, and molt alone can pause production for 8 to 16 weeks — so the first move isn’t panic, it’s ruling these out in order, starting with the ones that are normal and temporary before assuming illness.
A sudden drop in eggs is one of the most common reasons new keepers go looking for answers, and the good news is that most of the time the cause is completely normal — not a sign anything is wrong with the bird. This guide walks through the real causes in the order worth checking, with the numbers and sourcing behind each one.
The 8 causes, side by side
| Cause | How fast it resolves | Tell-tale sign |
|---|---|---|
| Molt | 8-16 weeks | Feather loss, usually fall, bird otherwise active |
| Short daylight | Resolves with added light or by spring | Slowdown starting Sept-Oct, no illness signs |
| Age (2+ years) | Permanent, gradual decline | Slow year-over-year drop, not a sudden stop |
| Stress (heat/predator/new bird) | Days to 1-2 weeks after trigger removed | Sudden stop tied to a specific event |
| Broodiness | 2-3 weeks, or until broken | Hen camped on nest, puffed up, growls/pecks when disturbed |
| Illness/parasites | Varies, needs treatment | Lethargy, pale comb, appetite loss alongside no eggs |
| Poor nutrition | 1-2 weeks after feed fixed | Thin, soft, or no-shell eggs before stopping fully |
| Hidden nest | Immediate once found | No eggs in the box but hen still active and healthy |
By the numbers
- Per Virginia Tech Cooperative Extension, hens need roughly 14 hours of daylight a day to keep their ovaries cycling, and day length needs to stay above about 12 hours just to maintain production — which is why laying naturally tapers off through fall and winter without supplemental light.
- Per Purina’s laying-hen guidance, a hen typically produces about 80% of her first-year egg count in her second year — a hen laying 250 eggs her first year drops to roughly 200 in year two under normal conditions, before declining further after two to three years.
- Molt is triggered by shortening days and typically lasts 8 to 16 weeks, and because feathers are about 85% protein, extension sources recommend switching to a higher-protein feed during this window to support regrowth without further draining the bird.
1. Check for molt first — it’s the most common cause
A higher-protein feed for molt season
- Most hens molt annually starting around 18 months old, usually in fall as days shorten, and it's completely normal to see feathers in the run and zero eggs for weeks at a time.
- A molt-specific or flock-raiser feed with higher protein content shortens the drain on the bird and can speed the return to laying.
- If feather loss looks patchy or concentrated around the vent rather than a whole-body shed, rule out mites or lice instead — see our chicken molting guide for how to tell the two apart.

2. Rule out short daylight hours

- A hen needs roughly 14 hours of light a day to keep laying; once natural daylight drops toward 12 hours or less in fall and winter, production slows or stops on its own.
- If you run supplemental light, it needs to run every single day once started — an inconsistent schedule does more harm than no light at all.
- The bulb doesn't need to be bright — just enough to read by — and pairing it with a timer avoids the discipline problem of remembering to flip a switch daily.
3. Consider age, stress, and illness together

- A gradual, year-over-year decline points to age — expect roughly an 80% first-year output in year two, then a further drop after two to three years depending on breed.
- A sudden stop tied to a specific event (heatwave, predator scare, a new bird introduced) points to stress rather than age or illness, and typically resolves within one to two weeks once the trigger is removed.
- If the stop comes with lethargy, appetite loss, or a pale comb, treat it as a health issue first — check our respiratory infection and coccidiosis guides for the illness-driven causes.
4. Do this, not that
| Do | Don't |
|---|---|
| Check the calendar and the bird's feathers first — molt and short days explain most slowdowns | Assume illness or jump to medicating before ruling out the normal, seasonal causes |
| Look for a hidden nest before concluding a hen has stopped laying entirely | Assume zero eggs in the box means zero eggs being laid |
| Run supplemental light on a consistent daily timer if you use it at all | Light the coop inconsistently — a skipped day can undo weeks of progress |
| Treat a sudden stop tied to a specific stress event as stress, not illness | Ignore a slowdown that comes with lethargy, pale comb, or appetite loss |
Most “my hen stopped laying” situations resolve on their own within a few weeks once you identify which of the eight causes is in play — molt and short daylight account for the majority of cases, especially heading into fall. The exceptions worth acting on fast are the ones layered with illness signs: lethargy, a pale or dusky comb, appetite loss, or diarrhea alongside the drop in eggs. In those cases, treat the drop as a symptom of something else rather than the problem itself, and work through it alongside whichever underlying issue you find — our coccidiosis and respiratory infection guides cover two of the more common culprits.
The bottom line
Before assuming the worst, check the calendar (is she due for a molt or is daylight shrinking?), her age (is she past her first year or two?), and her overall condition (active and eating, or lethargic and off her feed?). Most stopped-laying hens are dealing with a normal, temporary pause — molt, short days, stress, or broodiness — and resume within weeks once the cause passes or gets addressed. A hidden nest is worth a five-minute check before anything else, since it’s the fastest false alarm to rule out.
