Why Chickens Stop Laying Eggs and How to Fix It

Egg production in chickens can fluctuate due to various factors, and when hens stop laying, it can be concerning for poultry farmers. Understanding the causes behind this issue is essential to maintaining a productive flock. Several factors influence egg-laying cycles, ranging from seasonal changes to health conditions. Addressing these concerns properly helps ensure steady egg production and overall flock health.

Seasonal Changes and Light Exposure

One of the most common reasons chickens stop laying eggs is the change in daylight hours. Chickens require approximately 14 to 16 hours of light daily to maintain consistent egg production. As daylight decreases during the dry and wet seasons, their bodies naturally slow down egg-laying to conserve energy. This response is driven by their biological clock, which regulates hormonal levels responsible for reproduction.

Many poultry farmers use artificial lighting inside the coop to mitigate this seasonal decline. Adding supplemental light can help maintain the necessary exposure and keep hens laying throughout the wet season.

However, the intensity and duration of the light must be carefully managed to avoid stressing the birds. Using a gradual lighting schedule that mimics natural daylight transitions ensures a smooth adaptation and prevents sudden disruptions in laying patterns.

Although artificial lighting can extend the laying period, some farmers choose to let their hens follow natural cycles. Allowing a seasonal break can benefit their long-term health, as continuous egg production can be physically demanding.

A well-balanced diet and stress-free environment during this period support their overall well-being, preparing them for a strong return to laying when daylight increases.

Poor Nutrition and Deficiencies

Diet plays a crucial role in egg production, and any deficiency in essential nutrients can significantly impact laying performance. Protein, calcium, phosphorus, and vitamins such as D3 are fundamental for eggshell formation and reproductive health. When hens lack these nutrients, they may lay fewer eggs or stop entirely. Additionally, dieting with excess treats or low-quality grains can further imbalance their nutrition, leading to irregular laying cycles.

Providing a high-quality layer feed formulated for egg-laying chickens ensures they receive the necessary nutrients. Calcium sources like crushed oyster shells or limestone are vital for strong eggshell formation. A calcium deficiency often produces soft or shell-less eggs, which can stress the hen’s body and reduce overall production. Incorporating greens, mealworms, and various grains can enhance their diet while keeping them active and engaged.

Access to clean water is important, as dehydration can affect metabolism and hinder egg production. A hen’s body consists mostly of water, and an insufficient intake can disrupt digestion, nutrient absorption, and overall reproductive health.

Ensuring a constant supply of fresh water, especially during hot weather, supports optimal laying conditions and prevents heat stress, which can further contribute to reduced egg output.

Molting and Feather Renewal

Molting is a natural process where chickens shed old feathers and grow new ones, usually occurring once a year. During this period, their energy is redirected toward feather regeneration rather than egg production.

Molting can last from a few weeks to several months, depending on the breed and individual health of the hen. This cycle is essential for maintaining strong and healthy plumage, which provides insulation and protection against environmental conditions.

Supporting hens through molting requires dietary adjustments, particularly an increase in protein intake. Feathers are composed mostly of protein, so providing high-protein feed, such as mealworms, fish meal, or sunflower seeds, helps accelerate the process.

Ensuring they receive ample vitamins and minerals further strengthens their immune system, allowing them to recover faster and resume egg production efficiently.

Maintaining a stress-free environment during molting is equally important. Hens experiencing stress from aggressive flock mates, sudden changes in habitat, or improper handling may take longer to complete the molting cycle.

Providing a calm and secure area with ample space, perches, and dust baths helps reduce anxiety and allows for a smoother transition back to regular egg-laying patterns.

Stress and Environmental Factors

Stress is a major factor that can cause hens to stop laying eggs. Chickens are highly sensitive to their surroundings, and disruptions such as loud noises, predator threats, overcrowding, or sudden coop changes can significantly impact their egg production.

Even minor alterations, such as introducing new flock members or changing their routine, can lead to temporary drops in laying.

Creating a stable and secure environment is key to reducing stress and maintaining consistent egg production. Ensuring the coop is well-ventilated, predator-proof, and spacious prevents unnecessary disturbances.

Adequate nesting areas, perches, and access to outdoor space allow hens to engage in natural behaviors, promoting a sense of security and well-being.

Establishing a regular daily routine further minimizes stress levels. Feeding at consistent times, maintaining a clean coop, and handling hens gently can contribute to a calmer flock. When stress is managed effectively, hens feel more comfortable, which in turn supports their reproductive cycles and productivity.

Aging and Natural Decline

As hens age, their egg production naturally slows down. Most chickens lay the highest number of eggs during their first two years, with gradual declines thereafter. By the time they reach four to five years old, many hens lay sporadically or stop altogether. This process is entirely normal, as their reproductive system ages and becomes less efficient.

Recognizing the age-related decline allows poultry keepers to plan their flock management strategies. Introducing younger hens periodically ensures a steady egg supply while allowing older birds to live out their natural lifespan.

Some farmers choose to keep older hens for pest control and companionship, as they still contribute to the farm ecosystem in various ways.

Providing a nutritious diet, good living conditions, and routine health checks can help aging hens maintain their well-being. While egg production may decrease, ensuring they receive the right care supports their longevity and overall quality of life.

Health Issues and Parasites

A decline in egg production can also be linked to underlying health problems. Illnesses, infections, and diseases weaken a chicken’s body, diverting its energy away from laying eggs. Respiratory infections, bacterial diseases, and reproductive disorders can all negatively impact a hen's ability to lay.

Signs of illness may include lethargy, loss of appetite, abnormal droppings, or swelling around the eyes and beak. Early detection of such symptoms is important for maintaining a productive flock.

External parasites, such as mites and lice, feed on the blood and skin of chickens, causing irritation, discomfort, and even anemia in severe cases. Chickens infested with mites or lice often appear restless, have damaged feathers, and may frequently scratch or preen.

Infestations lead to stress, weight loss, and reduced nutrient absorption, all of which contribute to lower egg production.

Internal parasites, including roundworms and tapeworms, thrive in the digestive tract, competing for nutrients and leading to malnutrition. Chickens suffering from internal parasites may have pale combs, diarrhea, or appear underweight despite regular feeding. If left untreated, these conditions can significantly reduce the overall health of the flock and further delay egg-laying.

Conducting regular health checks and implementing strong biosecurity measures can prevent disease outbreaks and parasitic infestations. Chickens should be inspected for signs of mites, lice, or worms, especially around their vent area, under their wings, and on their legs.

Natural or medicated parasite treatments, such as diatomaceous earth or veterinary-prescribed dewormers, can help eliminate infestations.

Maintaining a clean and dry coop is equally important—regularly cleaning bedding, disinfecting nesting boxes, and ensuring proper ventilation minimizes the risk of disease and parasite spread. Keeping chickens in a stress-free, hygienic environment allows them to stay healthy and continue laying eggs consistently.

Presence of Broodiness

Some hens become broody, meaning they stop laying eggs to sit on their nests and hatch eggs instead. Broody hens may stay in the nesting box for long periods, refusing to leave even if they have no fertilized eggs.

If broodiness is affecting egg production, gently remove the hen from the nest and encourage movement. Cooling methods, such as placing the hen in a well-ventilated area or using a broody breaker cage, can help discourage this behavior.

Conclusion

Maintaining consistent egg production in chickens requires attention to several factors, from environmental changes to diet and overall health. By understanding the causes behind a decline in egg laying, such as seasonal light changes, poor nutrition, stress, and health issues, poultry keepers can take proactive steps to ensure a productive flock.

Providing a balanced diet, managing light exposure, reducing stress, and regularly monitoring health are essential practices for sustaining egg production and promoting the well-being of hens. By addressing these factors, you can keep your chickens healthy and ensure a steady supply of eggs.
