Why do eggs stop or slow down?
Have you ever wondered why your chickens suddenly stop laying eggs or why you collect fewer eggs than you used to? Well, egg production is a natural process that depends on several factors, including daylight, nutrition, age, stress, and overall health. Understanding these factors can help you as a poultry owner keep your hens healthy and maintain consistent egg production.
Changes in Daylight
One of the biggest reasons hens slow down in their egg-laying is a change in daylight. Hens rely on the amount of light they receive each day to regulate their reproductive systems. When the days become shorter in the fall and winter, their bodies may receive fewer signals to produce eggs.
Most laying hens need approximately 14–16 hours of light per day to maintain consistent egg production. During the shorter days of winter, hens may lay fewer eggs or temporarily stop laying altogether. Some poultry owners use supplemental lighting to maintain production, but they should introduce it carefully and consistently. On my farm, we have just a regular house light bulb that stays on in the chicken coop over winter. Some farmers have different colored lights, like red lights, that deeply stimulate egg-laying hormones. That’s for a different blog!
Nutrition and Water
Moving on, just like people, chickens need proper nutrition to stay healthy. Producing an egg requires energy, protein, calcium, and other essential nutrients. If hens do not receive enough of these nutrients, their egg production can decrease.
A quality layer feed provides the protein, vitamins, and minerals needed for egg production. Calcium is especially important because hens use it to form strong eggshells. If a hen does not receive enough calcium, she may produce eggs with thin shells or other shell-quality problems. We have had eggs with “wart”- like calcium spots or deformed eggshells that looked like a flat, dented football.
Water is equally important. Hens need constant access to clean, fresh water. Even a short period without enough water can cause egg production to drop. During hot weather, water intake becomes particularly important.
Age of the Hen
A hen's age also affects how many eggs she produces. Young hens usually begin laying eggs at around 18–24 weeks of age, depending on the breed and their development. They often reach their highest production during their first laying cycle. As hens get older, their egg production generally decreases. Older hens may lay fewer eggs, produce larger eggs, or experience more eggshell-quality problems. This is a normal part of the aging process and does not necessarily mean the hen is sick.
Stress and Environmental Changes
Stress can also cause hens to slow down or stop laying. Common stressors include extreme temperatures, predators, overcrowding, moving to a new coop, and sudden changes in their routine.
Heat stress is especially important during the summer. When chickens become too hot, they may eat less, drink more, and use their energy to regulate their body temperature rather than support egg production. Providing shade, ventilation, and plenty of clean water can help reduce heat stress.
Molting and Health Problems
Molting is the natural process in which chickens lose old feathers and grow new ones. During this time, hens use more nutrients and energy to replace their feathers, so egg production often decreases or stops temporarily.
Illnesses, parasites, and reproductive problems can also affect egg production. If a hen stops laying unexpectedly and also appears weak, loses weight, eats less, or behaves unusually, she may need to be examined by a veterinarian.
Summary
There are many reasons laying hens stop or slow down producing eggs. Changes in daylight, poor nutrition, lack of water, aging, stress, molting, and health problems can all play a role. By providing proper feed, fresh water, a comfortable environment, and regular health checks, poultry owners can help their hens stay healthy and productive. Remember: A decrease in egg production does not always mean something is wrong. Sometimes, it is simply a natural part of a hen's life cycle. Understanding what your hens need is the first step toward keeping a healthy flock and enjoying fresh eggs throughout the year.
