You walk out to the coop one morning, lift the nesting box lid, and find nothing. Not one egg. Yesterday there were four. The day before, five. You check again in the afternoon, just to be sure. Still nothing. If this sounds familiar, you’re not alone, and you’re also not doing anything wrong. Hens stop laying for more reasons than most beginners expect, and here’s the frustrating part: several of those reasons can be happening at the same time.
Light Is the Most Underestimated Factor in Your Flock
Your hen’s reproductive system is controlled almost entirely by light. Specifically, by the number of daylight hours she perceives each day. When day length drops below roughly 14 hours of light, her pituitary gland gets the signal to slow or stop egg production. This is why late fall and winter cause a dramatic drop in laying for most flocks, even when nothing else has changed.
The breeds most sensitive to this are also, ironically, some of the most popular ones. Leghorns, Rhode Island Reds, and Plymouth Rocks will all slow down significantly once you get below 12 hours of daylight. Easter Eggers and Ameraucanas tend to be a little more forgiving, but they’re not immune.
The practical fix is supplemental lighting. A simple incandescent or LED bulb in the coop on a timer, adding light in the early morning hours to bring the total to 14 to 16 hours, is usually enough to keep production going through winter. I use a basic outlet timer and a 40-watt equivalent LED bulb. Nothing fancy. Some people object to this on welfare grounds, and that’s a fair conversation to have with yourself. Hens have a finite number of eggs in them over a lifetime, and pushing winter production does mean potentially shorter productive years. But if you need eggs through January, that’s your call to make.
One thing people miss: the light needs to be bright enough. A dim 15-watt bulb hanging in a 10x10 coop probably isn’t doing much. You want at least 1 watt of incandescent-equivalent light per 4 square feet of floor space, with the bulb positioned so light reaches all the birds.
Molting Is Normal, But It Still Catches People Off Guard
Most laying hens go through a molt once a year, usually triggered by that same shortening of day length in late summer or early fall. During a molt, your hen will lose her feathers, look absolutely terrible for a few weeks, and produce zero eggs. This is not a disease. This is not a crisis. This is biology.
A typical molt lasts 8 to 16 weeks, though that range surprises people. High-production hens like Leghorns tend to molt hard and fast, maybe 8 weeks. Heritage breeds and older hens sometimes drag it out closer to 16. During this time, your hen is redirecting all her protein resources toward feather regrowth, and egg production shuts down completely.
What you should do during molt: bump up the protein in her diet. Standard layer feed runs about 16% protein. During molt, I switch my flock to a grower or all-flock feed at 18 to 20% protein, or I supplement with black oil sunflower seeds, mealworms, or scrambled eggs. Manna Pro Dried Mealworms are easy to keep on hand and hens go absolutely crazy for them. (This site may earn a commission on purchases.)
Don’t be surprised if a hen who molts in October doesn’t come back into full production until February or March. That’s normal. She’s not broken.
Age, Stress, and the Things You Can’t See From the Outside

| Factor | Duration | Impact on Laying |
|---|---|---|
| Molt | 8-16 weeks | Complete stop; protein needs increase |
| Winter (below 14 hours light) | Late fall through winter | Dramatic drop; recoverable with supplemental light |
| Peak laying years | Years 1-3 | 5+ eggs/week; declines after year 3 |
| Year 3-4 decline | Ongoing | 3 eggs/week down to 1-2 |
| Year 5+ | Ongoing | 1-2 eggs/week; may skip weeks |
| Stress recovery | ~2 weeks | Full resumption of normal laying |
| Post-molt return to production | February-March (if molted Oct) | Can be 4+ months after molt starts |
A hen’s peak laying years are her first two to three. After that, production declines. A two-year-old Buff Orpington who was laying 5 eggs a week might be down to 3 by year three, and down to 1 or 2 by year four. She may skip weeks entirely by year five. It’s not a sudden stop, but it can feel like one if you weren’t tracking her output closely.
Stress is a massive and often overlooked trigger for egg-laying disruption. The list of stressors is longer than most people expect:
- A new chicken added to the flock
- A predator scare (even one the chickens survived unharmed)
- Being moved to a new coop
- Extreme heat above 90°F or sudden cold snaps
- A change in feed brand or formula
- Running out of water, even for just a few hours
- A dog running along the fence line repeatedly
- Kids chasing the birds
Hens are prey animals. Their nervous systems are tuned to react to threats, and egg production is one of the first things to shut down when they feel unsafe. I’ve seen a single nighttime predator visit, a raccoon at the hardware cloth, stop a flock’s laying for two full weeks even though no birds were lost.
If something changed around the time your hen stopped laying, that’s your clue. Give her two weeks of calm, consistent routine before you panic.
Health Problems That Show Up as Stopped Laying
Sometimes a hen stops laying because something is wrong with her body, not just her environment. Here are the most common medical causes I’ve dealt with personally:
Egg binding is when an egg gets stuck in the oviduct and can’t pass. This is a veterinary emergency. Signs include a hen who is puffed up, sitting low to the ground, straining, not eating, and has a distended abdomen. If you suspect egg binding, warm soaks in a tub of 104°F water for 20 to 30 minutes can sometimes help, but she needs a vet if she doesn’t pass the egg within a few hours.
Internal laying or egg yolk peritonitis is more common than most people realize in high-production breeds. Egg material ends up in the abdominal cavity instead of the oviduct, and it causes chronic infection. Signs include a penguin-like stance, swollen abdomen, and gradual decline. There’s no good home treatment, and surgery is expensive with mixed outcomes. Some hens live for months with supportive care; others decline quickly.
Infectious bronchitis and other respiratory viruses can knock out egg production for weeks to months, and in some strains, permanently reduce laying capacity. If you notice respiratory symptoms alongside the laying stoppage, isolation and a vet consult are the right moves.
Lice and mites are sneaky production killers. A heavy mite load stresses a hen, drains her energy, and causes anemia. She’s not going to lay well if she’s covered in northern fowl mites. Check under the wings and around the vent area. If you see small moving specks or pale, anemic-looking combs, treat the birds and the coop. Elector PSP is expensive but genuinely effective. Diatomaceous earth in the dust bath area helps as a preventive.
Step-by-Step: How to Actually Diagnose Why Your Hen Stopped Laying
When a hen stops laying, work through these steps in order before drawing conclusions.
Step 1: Check the basics Confirm she has access to fresh water at all times. Check her feed. Make sure she’s actually eating. Weigh her if you can. A hen who is thin and dull-coated has a different problem than one who looks healthy and energetic.
Step 2: Count the daylight hours What time does the sun rise and set where you live right now? If you’re below 14 hours, light is likely a contributing factor. Sunrise/sunset calculators are free online and take 30 seconds.
Step 3: Check for molt Part her feathers and look at her skin. New pin feathers, bare patches, or lots of loose feathers in the coop are molt signs. No mystery there.
Step 4: Assess her stress level Has anything changed in the last two to four weeks? New flock members, new coop, feed change, construction noise nearby, predator activity? Identify it, address it where possible, and give her time.
Step 5: Do a hands-on physical check Pick her up. Feel her body condition. Check the vent area for mites. Press gently on her abdomen. A swollen, fluid-filled abdomen is a red flag for internal laying or ascites. A normal, soft abdomen is reassuring.
Step 6: Look for hidden nests Before you assume she stopped laying, check your entire yard. Hens who free-range are masters at hiding eggs. I once found 23 eggs under a rosemary bush that had been accumulating for two weeks.
Step 7: Give it two weeks Unless you see signs of illness or distress, give a healthy-looking hen two weeks before escalating. A lot of laying disruptions are temporary and self-resolving.
A Quick Comparison: Common Causes at a Glance
Sources
| Cause | Typical Duration | Eggs Return? | Action Needed |
|---|---|---|---|
| Seasonal light reduction | Ongoing through winter | Yes, with more light or spring | Add supplemental lighting or wait |
| Molt | 8 to 16 weeks | Yes | Increase protein, be patient |
| Stress | Days to weeks | Yes, once resolved | Identify and remove stressor |
| Age (over 3 years) | Permanent decline | Partially | Manage expectations |
| Egg binding | Days | Yes, if treated fast | Warm soak, vet if no improvement |
| Internal laying | Months, progressive | Often no | Supportive care, vet consult |
| Lice or mites | Weeks | Yes, after treatment | Treat birds and coop |
| Illness/respiratory | Weeks to months | Often partially | Vet consult, isolation |
The honest truth about keeping chickens is that egg production is a moving target. Light, age, health, stress, season, and biology are all pulling in different directions at once. A hen who laid reliably for two years isn’t broken just because she stopped last week. Work through the possibilities methodically, give her what she needs, and most of the time she’ll come back around. And if she doesn’t, well, that’s what retirement looks like for a chicken who’s earned it.
