Fresh eggs are one of the great joys of keeping chickens. But what happens when your hens suddenly stop laying?
Sometimes the reason is natural: age, moult, or a seasonal slowdown. Other times, it may be a sign of stress, poor diet, or health problems. The good news? There’s almost always an explanation, and something you can do about it.
In this guide, I’ll walk you through ten of the most common reasons why chickens stop laying, plus simple steps to get them back on track.
Quick insights from this article – especially helpful if you’ve noticed your egg basket looking emptier than usual.
Wondering what’s going on? Skip straight to the bit that fits your flock, or read it all to cover every possibility.
Before you decide your hens have downed tools, it’s worth ruling out three simple explanations. Sometimes eggs are still being laid – just not where you might expect!
1. Predators and vermin: some predators (like snakes or raccoons) and rodents such as rats and mice love a free meal. Eggs are the perfect takeaway.
Check your coop and run for tell-tale signs.
2. Free ranging: hens with free rein may lay their eggs anywhere but the nest box.
Make sure you comb the free ranging area for hidden stashes of eggs.
3. Egg eating: a difficult habit to break, and a fairly common issue in flocks. It can be a messy, stubborn habit to solve, but it can be done. Find out how in my detailed egg-eating article.
🐥 A note from my flock: this is one of my Lemon Millefleur Sablepoot roosters, Bono. Bono developed a taste for fresh eggs, much to the ladies’ annoyance – and mine!
He wore the evidence all over his feathers, so I had no doubt who the culprit was. He did learn his lesson, but it took time and patience.
Too young to lay?
Hens do not start laying eggs until they're mature, somewhere between 18 and 28 weeks of age, depending on breed and season.
Signs they’re nearly ready are:
Too old to lay?
Egg production peaks a couple of months after a hen starts, then slows down each year, so they will produce fewer, and smaller, eggs as they age.
By between 6 and 7 years many hens lay only occasionally, though some may continue up to 10 years(1).
🐥 A note from my flock: my Red Stars usually begin laying right on schedule at 20 weeks, while my Sussex ladies have often kept me waiting until nearly 28 weeks.
Not all breeds are created equal when it comes to eggs. Some hybrids are bred to lay almost daily, while many heritage breeds produce fewer eggs but bring other qualities to the flock.
Top performers:
There's no doubt about my top two best laying hens:
Feed and water are two of the biggest factors in egg production. Studies show that if either slips, your hens may slow down or stop laying altogether(1, 2).
One simple biological fact explains a lot about egg slowdowns: hens need around fourteen hours of daylight to trigger egg production.
As daylight hours shorten in autumn and winter, a hen's pituitary glands stop releasing the hormone that tells the ovaries to produce eggs. So fewer daylight hours mean, biologically, fewer (or no) eggs.
Which is why commercial farms keep lights on for between 14 and 16 hours.
However...
One of the most common reasons chickens stop laying is moulting.
Why does it affect eggs?
A broody hen is just a female chicken who has decided she wants to hatch chicks. It doesn't matter whether or not there's a male around to fertilise the eggs: her hormones take over and nothing will persuade her there's no point.
She’ll spend most of the day sitting on eggs – hers or anyone else’s – only leaving the nest briefly to eat and drink.
While she’s broody and sitting on her clutch, she will collect eggs, but won’t lay. In fact, many hens won’t start laying again for several weeks after the chicks have hatched.
Some breeds are far more likely to go broody than others. Silkies, Orpingtons, Brahmas and Cochins are famous for it, while hybrids such as Red Stars and Leghorns rarely bother(11).
There is some evidence that hens lay at a higher rate when they finish being broody, to compensate for eggs not laid during that time(10).
A sick chicken will put her energy into trying to regain health and egg laying slows down or stops. It can be the first sign that spmething's physically wrong.
Chickens cope far better with cold than with heat. When temperatures rise, egg laying is often one of the first things to stop: it's a sure sign of heat exhaustion in chickens.
In humid areas (around 50% humidity or more), mild heat stress can set in as low as 20ºC (68ºF). By 30ºC (86ºF), the risk of heat stroke is high.
In drier climates, birds tolerate heat a little better, but once temperatures reach 40ºC (104ºF), heat exhaustion – and death – become likely(12).
Egg production drops or stops altogether because the hen’s body diverts energy away from laying and into survival.
Chickens are naturally nervous creatures: after all, almost everything sees them as an easy lunch! A sudden change in their environment or a constant source of worry can be enough to release a flood of stress hormones, which switch off egg production.
Common stress triggers include:
Chickens can deal with stress if they are provided with the means to adapt to the cause.
So the first step is to identify that your chickens are stressed.
🐥 A note from my flock: we have a pair of buzzards that regularly circle over our valley. They never come near the run, but simply hearing their cry is enough to put some of my hens off laying for days.
It’s a reminder that even unseen predators can unsettle a flock.
Hens can be surprisingly fussy about where they lay. If your chickens have stopped laying in the coop, it may be the nest boxes that are putting them off.
Research shows hens without suitable nest boxes show stressed behaviour and higher levels of stress hormones(14).
And stress, of course, means fewer eggs.
Why have my chickens suddenly stopped laying eggs?
Common causes include moulting, stress, heat, poor diet and reduced daylight hours. Use this article to assess the issues for your own flock.
At what age do chickens stop laying eggs?
Most hens peak in their first two years, then gradually slow down. By between six and seven years many stop altogether, although some will lay occasionally into old age.
Do chickens lay eggs all year round?
Not naturally. In winter, shorter days mean fewer eggs unless artificial light is added. Many keepers prefer to give hens a seasonal rest.
How can I get my chickens to lay more eggs?
A hen cannot physically produce more than one egg a day, but we can help our hens by providing a balanced layer feed, clean water, good nest boxes, and minimise stress.
Adding extra artificial light in winter can help, but isn’t essential if you prefer a natural cycle.
Do mites stop chickens laying eggs?
Yes. Mites, lice, and other parasites drain a chicken’s energy and can reduce egg production by 20% or more.
Keeping on top of coop and run hygiene is essential.
A lot of "facts" you'll find on the internet are often people's individual views, based on inaccurate information repeated from poor quality sources.
The information I provide in this article and others is based not just on my own experience, but on evidenced facts from scientific, peer-reviewed research and books from highly respected and experienced poultry keepers such as Gail Damerow.
