Why Your Hens Stop Laying in Autumn (And What to Do About It)

The short answer: yes, it's normal

If your nest boxes went quiet somewhere between late August and November, your hens are almost certainly doing exactly what hens have always done. Autumn is the season of the moult and the season of shrinking daylight, and those two things together put egg production on pause for most backyard flocks.

It can feel alarming anyway. One week you're giving eggs to the neighbours, the next you're buying them at the shop while twelve well-fed birds stare at you from the run. But a seasonal stop is a sign of a bird following her biology, not a bird in trouble.

A hen who stops laying in autumn isn't broken. She's refurbishing.

What the moult actually is

Feathers are mostly protein, and they wear out. Once a year, usually after their first full laying season and then each autumn after, hens shed and regrow them. You'll see the run look like a pillow fight happened, bald patches down the neck and back, and spiky grey "pin feathers" pushing through like paintbrush handles.

Growing a whole new coat is expensive. The protein and energy that went into shells and yolks gets redirected into feathers, so laying stops or drops to almost nothing. A fast moulter may be through it in six weeks; a slow, tidy moulter can take three months or more. Oddly, the scruffy, dramatic moulters tend to be your best layers — they get it over with.

Moulting birds are often sore to handle. Those pin feathers have a live blood supply and genuinely hurt if knocked, so this is a good few weeks to go easy on the cuddles and the shuffling of birds between coops.

The daylight part

A hen's reproductive cycle is triggered by light hitting receptors in her brain, not by temperature. Most hens need somewhere around fourteen hours of daylight to keep ovulating reliably. In the UK that threshold disappears around September and doesn't come back until late February or March.

So even a hen who has finished moulting may simply sit out the winter and resume when the light does. Point-of-lay pullets hatched in spring often carry on laying straight through their first winter — they skip their first moult — which is why a mixed-age flock usually gives you at least a few eggs year round.

Should you add artificial light?

You can. Commercial flocks do, and a low-wattage lamp on a timer that adds light in the early morning, bringing the total to fourteen hours or so, will usually restart laying. Add it to the morning end rather than the evening, so birds aren't plunged into sudden darkness away from the perch.

Whether you should is a fairer question, and keepers disagree. A hen is born with a finite number of ova; pushing her through winter doesn't create more eggs, it just spends them sooner. There's a reasonable argument that the winter rest is good for a bird who is going to live with you for years rather than months. If your flock are pets who happen to lay, letting them pause is a perfectly defensible choice.

Age, and the quiet maths of it

Hens lay best in their first full year. After that, production typically falls by roughly a fifth to a quarter each year, though the eggs often get bigger. By year four or five, many hens lay only sporadically — a handful in spring and then nothing. Ex-commercial hybrids, bred to lay hard and fast, often tail off earlier than heritage breeds.

If your flock all arrived together three years ago and all went quiet at once, age is as likely an explanation as the season.

What to rule out before you worry

Most autumn stops need nothing but patience. A few don't. Work through this list:

• Hidden nests. Free-ranging hens are superb at finding a spot under a hedge or behind the log pile. Shut them in the run for a few days and see what appears.
• Egg eating. Look for yolk smears, broken shell fragments, or a hen with a suspiciously eggy beak. It starts with one accidentally cracked egg and becomes a habit fast.
• Red mite. Check the coop after dark with a torch, especially perch ends and crevices. Pale combs, birds reluctant to roost, and grey or red ash-like deposits are the signs. A heavy infestation stops laying cold.
• Worms and lice. Part the feathers around the vent. Consider a worm count or a vet-advised treatment if it's been a while.
• Stress. A new bird, a fox at the fence, a rehomed hen, a dog, building work. Laying is the first thing to go and often takes a fortnight to come back.
• Feed. Layers pellets left out in the rain lose vitamins. Too many kitchen scraps or too much corn dilute the ration.
• Water. A frozen or fouled drinker for even half a day knocks laying for days afterwards.

Feeding through the moult

Feathers are around 85 per cent protein, so this is the one time of year a protein lift genuinely helps. Switching from standard layers pellets (roughly 16 per cent protein) to a grower or all-round poultry feed at 18 to 20 per cent for the duration of the moult supports regrowth. Sunflower hearts, mealworms where legally permitted in your country, cooked egg, or a little tinned fish make good occasional toppers.

Keep oyster shell available in a separate dish regardless. Hens self-regulate calcium, and the ones still laying will take what they need.

Cut back on corn and scratch, which is mostly energy and little else. And keep the coop dry and draught-free without sealing it up — a half-feathered hen in a damp, ammonia-heavy shed has a much harder time of it.

What a normal pause looks like

Bright red comb and wattles fading to pale pink, a scruffy coat, a drop in appetite for a week or two, and perfectly ordinary behaviour otherwise: scratching, dust bathing, bickering over the best perch. That's a hen on a break.

The thing to watch for isn't the absence of eggs. It's the presence of other symptoms alongside it.
