Why have my chickens stopped laying eggs this season and what to check

Part of the guide: Chicken egg incubation day by day: what to expect and do each day

Common causes for hens to stop laying

Hens commonly stop laying because of environmental changes, health issues, or diet. Lack of adequate daylight under 14 hours per day often triggers laying pause.

Nutrition gaps, especially calcium or protein deficiency, reduce egg production. Stress from predators, loud noises, or coop disruptions also halts laying temporarily.

Age naturally reduces laying after about 2-3 years. Illnesses like respiratory infections or parasites can cause an abrupt stop.

Checking these causes helps identify what triggers your hens’ pause in egg laying quickly. We cover how to handle hens not laying in its own article.

A sudden stop in laying might also signal a hidden problem like molting. Molting happens when hens shed old feathers and regrow new ones, a process that uses nutrients and energy. During molting, hens stop laying to focus on feather replacement. This pause can last from 6 to 12 weeks depending on the bird's health and environment. Noticing feather loss and dull plumage can confirm molting as the cause.

If you spot sudden changes in behavior like hiding or aggression, check for pecking injuries or bullying in the flock. Dominant hens can stress others enough to stop their laying temporarily. Separating aggressive birds or increasing feeder space often restores calm and egg production. Keep a daily record of which hens lay and when to spot patterns or individuals affected. This can help catch subtle issues before they cause a full stop.

• Daylight hours: less than 14 decreases laying
• Nutrition: low calcium or protein stalls eggs
• Stress: predators or coop disruption reduce laying
• Age: steady decline after 2-3 years
• Illness: symptoms like sneezing or lethargy

Seasonal and environmental factors affecting laying

The most common seasonal cause is decreasing daylight in fall and winter. Hens need at least 14 hours of light daily to sustain egg production. We go through how to care for molting chickens step by step elsewhere on the site.

Cold weather alone does not stop laying but can increase energy needs. Insufficient shelter and dampness increase stress, reducing egg output.

Changes in temperature or humidity can disrupt laying cycles for days or weeks. Artificial lighting can extend laying into shorter days if consistent.

Environmental disturbances like predators near the coop or new noises can cause hens to stop laying temporarily.

Artificial lighting needs to be steady and consistent to work. Flickering or irregular light schedules can confuse hens, causing irregular laying or pauses. Use timers to ensure 14 to 16 hours of continuous light. Low wattage bulbs around 10-15 watts per 100 square feet work well. Avoid bright lights at night that disturb sleep, which can reduce laying.

Humidity levels over 70% or very dry air below 30% can stress hens. A coop with poor airflow traps moisture, leading to respiratory problems and laying decline. Use vents placed high on walls to allow moist air to escape. In winter, balance warmth with ventilation to prevent dampness. Monitor with a simple indoor hygrometer showing % humidity to keep conditions optimal.

Extreme weather swings also disrupt laying. A sudden cold snap after warm days can cause hens to hold eggs or drop laying for a few days. Check that water doesn’t freeze and that feed is fresh and plentiful to meet raised energy needs. A hen needs about 300 calories more daily in cold weather to maintain body heat and laying.

• Daylight: critical trigger for egg production
• Temperature: cold ups energy but not main stop cause
• Shelter: dampness and drafts stress birds
• Disturbances: predators or noise stop laying
• Artificial light: extends laying in short days

Health and nutrition issues that stop laying

Calcium deficiency is a leading nutritional cause. Hens need about 3-4 grams of calcium daily to form eggshells properly.

Protein intake around 16-18% of diet supports egg production. Poor diets or sudden feed changes reduce laying.

Parasites, infections, or internal diseases cause laying to stop abruptly. Signs include weight loss, droopy posture, or discharge.

Regular health checks and maintaining clean, parasite-free housing prevent these issues. A veterinarian can test for common diseases.

If eggshells are thin or soft, calcium supplementation with oyster shell or crushed limestone is needed immediately.

Vitamin D3 is essential for calcium absorption. Deficiency can cause poor eggshell quality and stop laying. Hens get Vitamin D3 from sunlight exposure or supplements in feed. If hens stay mostly indoors or during winter months, add Vitamin D3 supplements to their diet.

Protein quality matters as much as quantity. Feed with the right balance of amino acids supports egg formation. Sudden diet changes, like switching feed brands without transition, cause stress that reduces laying. Introduce new feeds gradually over 7 to 10 days.

Dehydration also halts laying. A hen requires about 250 ml (8.5 oz) of water daily during laying. Dirty, frozen, or hard-to-access water reduces intake. Check waterers daily and keep them clean to encourage drinking. A dip in water intake quickly shows as fewer or no eggs.

• Calcium: 3-4 g needed daily for shells
• Protein: 16-18% of diet for laying
• Illness signs: lethargy, weight loss, discharges
• Parasite control: regular deworming critical
• Health checkups: essential for diagnosis

Age-related laying decline in chickens

Hens usually peak egg production around their first year, then decline after 2-3 years. Egg quantity and quality drop steadily.

Older hens lay fewer eggs with thinner shells and often skip days more frequently. This decline is natural and irreversible.

Some breeds slow laying earlier or later depending on genetics. Backyard hens kept for eggs often retire around 4-5 years.

Replacing older hens with pullets keeps your flock’s egg supply steady. However, older hens still provide value beyond laying.

Understanding age limits helps you plan flock rotation and avoid frustration over reduced egg output.

Some backyard hens can lay consistently for 5 years or more, but usually at reduced rates after year three. Breeds like Leghorns tend to lay longer, while heavier breeds decline faster. Tracking egg production by individual hens helps decide when to replace them.

You can stimulate some older hens to lay more by adding light hours or improving feed quality. However, expect diminishing returns as ovarian follicles deplete. The cost of feed for low-producing hens sometimes outweighs the eggs gained.

Egg size generally increases with hen age. A 2-year-old hen’s eggs may weigh around 55 grams, while a 4-year-old’s can reach 65 grams. This size increase does not compensate for fewer eggs and thinner shells. Knowing this helps manage expectations for older birds.

Stress and housing changes that affect laying

Stress from moving coops, new flock members, or predators causes hens to stop laying for several days up to weeks.

Overcrowding or poor ventilation in the coop increases stress hormones, lowering egg production.

Sudden changes in feed or water availability also disrupt laying.

Stable, calm housing with proper space, light, and protection minimizes stress and sustains laying.

Observe your hens’ behavior for signs like feather pecking or hiding, which indicate distress that affects laying.

Stress hormones like corticosterone rise quickly after a predator scare, sometimes within minutes. This hormone blocks reproductive hormones and sends hens into a laying pause. Even brief repeated disturbances can keep hens in stress mode for weeks.

New flock members introduce social stress. Pecking order fights and unfamiliar smells cause anxiety and reduced laying. Quarantine new hens for at least two weeks and introduce them gradually to minimize stress.

Housing changes that disrupt the daily routine cause laying to pause. Moving nests, changing feeder types, or adjusting lighting can unsettle hens. Keep changes minimal and consistent. If you must move a coop, do so in cooler parts of the day when birds are calmer.

• Coop moves: pause of days to weeks
• Predators: cause immediate stress response
• Overcrowding: raises stress hormones
• Feed/water changes: disrupt laying cycle
• Behavior signs: feather pecking, hiding

What happens physiologically when laying stops

Egg production depends on a hormone cycle controlled by daylight and stress signals. Reduced daylight lowers reproductive hormone levels.

Stress increases corticosterone, which suppresses reproductive hormones and ovulation.

Calcium depletion impairs eggshell formation, triggering the body to halt eggs until calcium stores rebuild.

Older hens experience follicle depletion in the ovaries causing fewer eggs laid.

Understanding this helps you see why restoring conditions like light, nutrition, and calm promotes laying again.
