Why might my hens stop laying eggs suddenly?

May 8, 2026

Quick Answer

Hens may stop laying eggs suddenly due to stress, nutritional deficiencies, or changes in lighting, temperature, or social hierarchy within the flock.

Stress and Nutritional Factors

Stress is a common reason for egg production to drop. Introduce too many new birds to the flock, or change the coop layout, and hens may become anxious. Nutritional issues, such as a lack of calcium or protein, can also cause egg production to decline. Provide a balanced layer feed that meets the nutritional needs of your hens, and ensure access to fresh water at all times. A calcium supplement can be added to their feed to support strong eggshell production.

Lighting and Temperature

Lighting plays a crucial role in regulating the reproductive cycle of hens. Most breeds require around 14 hours of daylight to produce eggs. Ensure the coop receives sufficient natural light, or supplement with artificial lighting if necessary. Temperature fluctuations can also impact egg production. Aim for a comfortable temperature range of 40°F to 80°F (4°C to 27°C) within the coop.

Social Hierarchy and Health

The social hierarchy within the flock can also influence egg production. If an older or dominant hen is removed, the younger birds may experience stress, leading to a drop in egg production. Regular monitoring of the flock’s health is essential. Check for signs of disease, such as labored breathing, lethargy, or changes in droppings. Consult a veterinarian experienced in poultry care if you suspect a health issue is affecting egg production.
