Why Chickens Stop Laying Eggs: 7 Common Causes
TL;DR: A hen stops or slows laying for one of seven common reasons: molt, shortening daylight, age, stress, poor nutrition, broodiness, or illness. Most — molt, daylight, stress, broodiness — are normal and temporary. Nutrition problems and illness need a direct fix. Telling them apart starts with checking whether the hen looks and acts otherwise healthy.
A hen that stops laying is one of the most common questions a backyard keeper runs into, and the honest answer is that it’s rarely one single thing — it’s usually one of a short, well-understood list of causes. This guide walks through all seven, with the goal of helping you tell a normal pause from something that actually needs attention.
Why Does Molting Stop Egg Production?
A hen redirects protein and energy toward growing new feathers during her annual molt, and that leaves less available for egg production — feathers are close to 85% protein by composition, so a full feather regrowth is a genuinely protein-intensive task. Laying commonly slows or stops entirely during the heaviest part of a molt and resumes once the new coat is mostly grown in.
Most chickens have their first adult molt around 18 months of age, then molt annually after that, with a typical molt lasting 4-8 weeks. This is a normal, healthy cycle, not a malfunction — see ManokHub’s full chicken molting guide for the complete timeline and how to support a bird through it.
How Does Daylight Affect Whether a Hen Lays?
Hens generally need meaningful daylight exposure to sustain peak egg production, and shortening day length is a natural biological trigger for reduced laying, separate from any illness or nutrition issue. In the Philippines, day length varies less across the year than in temperate climates, which softens this effect somewhat compared to countries with sharp seasonal swings — but it doesn’t remove it entirely, and a run of unusually overcast or shortened-daylight days can still show up as fewer eggs.
Does Age Alone Stop a Hen From Laying?
Not outright, but output gradually declines after a hen’s first year or two of peak production. A hen that reached point of lay and had a strong first year won’t necessarily maintain that exact pace forever — a gradual decline over subsequent years is normal, though many hens keep laying at a reduced but real rate well beyond their peak window rather than stopping completely.
Can Stress Stop a Hen From Laying?
Yes — a predator scare, a sudden change in housing, extreme heat, or new birds introduced to the flock can all suppress laying temporarily, since a stressed hen’s body prioritizes survival responses over reproduction. This is a short-term effect in most cases; laying typically resumes once the stressor is removed and the flock settles.
Heat stress specifically is worth watching in the Philippine climate — see keeping chickens cool in Philippine heat for how heat affects a flock generally, egg production included.
What Does Poor Nutrition Do to Egg Production?
A hen without enough protein or calcium in her diet cannot sustain consistent laying, regardless of how good everything else is. This is one of the more directly fixable causes on this list — see best layer feed in the Philippines for what an actively laying hen actually needs, roughly 18-20% crude protein plus meaningfully more calcium than a non-laying adult.
Unlike molt or daylight, a nutrition shortfall doesn’t resolve on its own — it persists until the diet is corrected.
What Is Broodiness and Why Does It Stop Laying?
A broody hen has switched into incubation mode — she stops laying new eggs and instead sits on a clutch, fertile or not, trying to hatch them. It’s a hormonal, instinctive behavior rather than a health problem, and it’s more common in some breeds and in free-range or native hens than in commercial layer types bred to suppress the instinct.
Broodiness can last several weeks. Some keepers let a broody hen sit it out; others actively break broodiness (by removing her from the nest repeatedly, or housing her separately without a nest site) to get her back to laying sooner. Either approach is reasonable — broodiness itself isn’t a problem to fix so much as a phase to manage.
When Is Illness the Real Cause?
Illness is the cause worth ruling in or out carefully, because unlike the other six causes on this list, it needs direct treatment rather than time. A hen that stops laying but keeps eating, moving, and acting normally is more likely dealing with molt, daylight, stress, or broodiness. A hen that stops laying alongside other symptoms — lethargy, appetite loss, abnormal droppings, respiratory sounds, or visible weight loss — is more likely genuinely sick.
| Cause | Typical duration | Other symptoms alongside it |
|---|---|---|
| Molt | 4-8 weeks | Visible feather loss, otherwise normal behavior |
| Daylight | Seasonal, gradual | None — hen behaves normally |
| Age | Gradual, permanent decline | None — hen behaves normally |
| Stress | Days to a couple weeks | Skittishness, hiding, resolves once stressor removed |
| Poor nutrition | Until diet corrected | Thin or soft-shelled eggs before laying stops entirely |
| Broodiness | Several weeks | Sitting on nest, aggressive when disturbed, otherwise alert |
| Illness | Varies by disease | Lethargy, appetite loss, abnormal droppings, respiratory signs |
Several ManokHub health guides cover the diseases most likely to affect a backyard flock’s condition and, by extension, its laying — coccidiosis, internal parasites, fowl typhoid and pullorum, and Newcastle disease among them. A consistent deworming schedule and basic flock biosecurity reduce how often illness becomes the actual answer here.
Can You Get a Hen Laying Again?
In most cases, yes — once the specific cause is addressed, laying typically resumes on its own rather than needing an active fix. A molting hen starts laying again once her feathers finish regrowing; a hen affected by shortening daylight often picks back up as days lengthen or if her environment provides more consistent light; a stressed hen recovers once the stressor is removed and the flock settles; a broody hen resumes once broodiness breaks, whether left to run its course or actively interrupted.
Nutrition and illness are the two causes that genuinely need intervention rather than time — a hen on an inadequate diet won’t resume consistent laying until the diet is corrected, and a sick hen needs treatment for the underlying disease, not just patience. This is why sorting out which of the seven causes is actually in play matters more than any single universal fix: the right response depends entirely on which one you’re dealing with.
The Honest Limits Here
This list covers the common, well-documented causes of reduced laying — it isn’t exhaustive, and a hen showing symptoms that don’t clearly match any of the seven above, especially alongside signs of real illness, is worth a vet’s evaluation rather than more guessing at home. This guide also doesn’t attempt to diagnose a specific case; it’s a framework for narrowing down what’s likely, not a substitute for watching your own bird closely.

Frequently Asked Questions
What are the most common reasons a hen stops laying eggs?
Molt, shortening daylight, age, stress, poor nutrition, broodiness, and illness account for the large majority of laying stoppages in a backyard flock. Most are temporary and resolve on their own once the underlying cause passes.
Why does a hen stop laying during a molt?
Feather regrowth is protein-intensive, and a hen's body redirects protein and energy away from egg production toward growing new feathers. Laying typically resumes once the molt is mostly complete.
Does daylight really affect egg production?
Yes. Hens generally need meaningful daylight exposure to sustain peak laying, and shortening day length is a natural trigger for reduced output, separate from any health issue.
What is a broody hen and why does she stop laying?
A broody hen has switched into incubation mode — she stops laying and instead sits on a clutch of eggs (fertile or not) trying to hatch them. It is a hormonal, instinctive state, not illness, and laying resumes once broodiness breaks.
Can stress alone stop a hen from laying?
Yes. A predator scare, a sudden housing change, extreme heat, or the introduction of new birds to the flock can all suppress laying temporarily as the hen's body prioritizes survival over reproduction.
How do you tell if a hen stopped laying from illness rather than a normal cause?
Illness usually comes with other symptoms beyond reduced laying — lethargy, appetite loss, abnormal droppings, or respiratory signs. A hen that stops laying but otherwise eats, moves, and acts normally is more likely dealing with molt, daylight, stress, or broodiness than disease.
Do older hens simply stop laying permanently?
Not usually outright. Output gradually declines after a hen's peak first year or two, but many hens continue laying at a reduced rate for years rather than stopping completely.
