Nothing frustrates chicken keepers more than empty nest boxes. Whether your pullets are 22 weeks old and still haven't started, your 32-week-old layers have gone quiet, or a 40-week-old flock has dropped off a cliff, the cause is almost always identifiable — and usually fixable. The single most useful piece of information is the flock's age in weeks, so this guide starts there before working through 21 common reasons chickens stop laying eggs and what to do about each one.
Normal Egg Production Expectations
Healthy laying hens typically produce 4-6 eggs per week during peak production. Production naturally varies by breed, age, season, and individual bird characteristics.
Quick Diagnostic Checklist
Before diving into detailed causes, run through this quick checklist to identify obvious issues:
- Are your hens at least 18-24 weeks old?
- Are they getting 14+ hours of daylight or artificial light?
- Is their feed fresh and appropriate for laying hens?
- Do they have constant access to fresh water?
- Are nest boxes clean and accessible?
- Have there been recent changes to their environment?
- Are they showing any signs of illness or stress?
What to Expect by Flock Age
Egg production follows a predictable curve. Matching your flock's age in weeks against that curve tells you immediately whether you have a real problem or a normal stage. Count from hatch date, not from the day you brought the birds home.
| Age of flock | What is normal | What it usually means if they are not laying |
|---|---|---|
| 16–20 weeks | No eggs yet for most breeds; combs reddening | Nothing — this is normal. Switch to layer feed only once the first eggs appear. |
| 20–26 weeks | First eggs, often small, soft-shelled or irregular | Late-maturing breed, short daylight, or under-conditioned birds. Check body weight before anything else. |
| 26–35 weeks | Peak lay — 5–6 eggs per hen per week | A flock at 32–36 weeks with no eggs is abnormal. Look for hidden nests, feed calcium and protein shortfalls, mites, or a recent stressor. |
| 35–50 weeks | A gentle decline from peak, roughly 4–5 eggs per week | A sharp stop around 40 weeks is nearly always feed quality, day length, parasites or disease — not age. |
| 50–80 weeks | First adult molt; production pauses for 8–12 weeks | Usually the annual molt. Feather loss with no eggs at this age is expected, not a fault. |
| Year 2 and beyond | Roughly 15–20% fewer eggs each year, larger in size | Genuine age-related decline. Manage expectations rather than chasing a cause. |
Early laying and very late laying
Some pullets lay before 18 weeks, usually because they were hatched under long spring days or fed a high-energy ration. Very early eggs are small, often shell-less, and occasionally cause egg binding in a bird that has not finished growing. Slowing them down — grower feed rather than layer feed, no supplementary light — is safer than encouraging them.
At the other end, a pullet still not laying at 30 weeks is normally a body-condition problem. Weigh a few birds: a hen that is under target weight for her breed will hold off laying until she catches up, however good the feed looks. Heritage and dual-purpose breeds routinely start six to eight weeks later than commercial hybrids, so check what you actually bought before assuming something is wrong.
Age-Related Issues
1. Too Young to Lay
Cause: Pullets haven't reached sexual maturity.
Solution: Most breeds begin laying between 18-24 weeks. Larger breeds may take longer. Be patient and ensure proper nutrition to support development.
2. End of Production Peak
Cause: Hens over 2-3 years old naturally decrease production.
Solution: While you can't reverse aging, proper nutrition, lighting, and care can maintain reasonable production in older hens.
3. Molting Season
Cause: Annual feather replacement diverts energy from egg production.
Solution: Provide high-protein feed (18-20%) during molt. Production resumes once new feathers grow in, typically 8-12 weeks.
Nutrition and Feed Problems
4. Wrong Feed Type
Cause: Using chick starter or grower feed instead of layer feed.
Solution: Switch to a quality 16–18% protein layer feed with adequate calcium (3.5-4.5%). Transition gradually over 7-10 days.
5. Calcium Deficiency
Cause: Insufficient calcium leads to soft-shelled or shell-less eggs.
Solution: Offer crushed oyster shell free-choice. Ensure layer feed contains adequate calcium or supplement with crushed eggshells.
The three things laying hens need most
If production has dropped, start with the basics: a complete layer ration, free-choice calcium, and clean water that never freezes. These are the most common fixable causes.
Layer feed (16–18%)
Complete ration with the protein and calcium hens need to lay.

6. Poor Quality or Spoiled Feed
Cause: Moldy, rancid, or nutritionally depleted feed.
Solution: Store feed in cool, dry conditions. Use within 3 months of milling. Check for off odors, mold, or pest contamination.
7. Inadequate Water Access
Cause: Dirty, frozen, or insufficient water reduces egg production rapidly.
Solution: Provide fresh water daily. Each hen needs 0.5-1 pint per day, more in hot weather. Use a heated waterer in winter.
8. Too Many Treats
Cause: Excessive treats dilute balanced nutrition.
Solution: Limit treats to 10% of total diet. Focus on nutritious options like leafy greens, vegetables, and occasional protein sources.
Environmental Factors
9. Insufficient Lighting
Cause: Hens need 14-16 hours of light daily for optimal production.
Solution: Add artificial lighting in winter. Use a timer to provide consistent light schedules. Gradual changes prevent shock.
10. Temperature Extremes
Cause: Heat stress above 80°F or cold stress below 32°F reduces laying.
Solution: Provide shade, ventilation, and cool water in summer. Insulate coops and use safe heating in winter. Optimal range: 45-75°F.
11. Poor Nest Box Conditions
Cause: Dirty, crowded, or poorly positioned nest boxes discourage laying.
Solution: Maintain 1 box per 4-5 hens. Keep boxes clean, dark, and quiet. Position 18-24 inches off ground with easy access.
12. Inadequate Ventilation
Cause: Poor air quality from ammonia buildup stresses birds.
Solution: Ensure adequate ventilation without drafts. Clean bedding regularly. Aim for 1 square foot of ventilation per 10 square feet of floor space.
Health and Stress Issues
13. Parasites (Internal or External)
Cause: Worms, mites, or lice drain energy and cause stress.
Solution: Regular health checks and preventive treatments. Consult our worming guide and mite treatment protocols.
14. Disease or Illness
Cause: Respiratory infections, reproductive disorders, or systemic illness.
Solution: Monitor for symptoms like lethargy, loss of appetite, or respiratory distress. Isolate sick birds and consult a veterinarian.
15. Stress from Predators
Cause: Predator pressure, even without successful attacks, creates chronic stress.
Solution: Improve coop security. Use hardware cloth instead of chicken wire. Install motion lights and remove attractants.
16. Overcrowding
Cause: Insufficient space increases aggression and stress.
Solution: Provide minimum 4 square feet per bird in coop, 10 square feet in run. Consider expanding or reducing flock size.
17. Social Disruption
Cause: Adding or removing birds disrupts pecking order.
Solution: Quarantine new birds before introduction. Use gradual integration techniques. Provide multiple feeding and watering stations.
Seasonal Factors
18. Natural Winter Decline
Cause: Shorter daylight triggers natural production decrease.
Solution: Accept natural seasonal variation or add artificial lighting. Some keepers prefer giving hens a winter rest.
19. Broodiness
Cause: Maternal instinct stops egg production while hen tries to incubate eggs.
Solution: Break broodiness by removing hen from nest, providing cool environment, or using specialized broody breaker cages. See our broody hen guide.
Management Issues
20. Egg Eating
Cause: Hens eating their own or others' eggs.
Solution: Collect eggs frequently. Provide adequate calcium and protein. Use fake eggs or nest box modifications to break the habit.
21. Hidden Nesting Sites
Cause: Hens laying in secret locations outside designated boxes.
Solution: Keep hens confined to coop until mid-morning. Search for hidden nests. Make nest boxes more attractive than alternative sites.

- Changes take 2-4 weeks to show results
- Keep detailed records to track improvements
- Seek veterinary help for persistent or severe problems
Reduced egg production is frustrating but usually temporary. By systematically addressing potential causes and maintaining good husbandry practices, you can restore your flock's productivity. Remember that some seasonal variation is natural, and older hens naturally decrease production over time. Once eggs return, the egg storage and food safety guide covers how long they keep and whether to wash them; for the wider arc of how production changes year to year, see lifespan and life stages.
Frequently Asked Questions
Why have my chickens suddenly stopped laying eggs?
Sudden drops are most often caused by shorter daylight, molting, a recent stressor (predators, new birds, heat), or a switch in feed. Hens need 14–16 hours of light and a 16–18% protein layer ration to keep laying. Rule out illness and parasites, then check light, feed, water and stress in that order.
At what age do hens start and stop laying?
Most breeds begin laying at 18–24 weeks. Production peaks in the first 1–2 years, then declines roughly 10–15% per year. Many hens still lay usefully into years three and four, especially heritage breeds.
Do chickens stop laying in winter?
Yes. As daylight drops below about 14 hours, laying slows or stops. You can add a timer-controlled light to maintain production, or allow a natural winter rest, which many keepers prefer for long-term hen health.
What can I feed chickens to make them lay more eggs?
Feed a complete layer ration with 16–18% protein and 3.5–4.5% calcium, offer oyster shell free-choice for shell strength, provide constant fresh water, and keep treats under 10% of the diet so they don't dilute nutrition.
