What is the major cause of poor egg production in hens?

Stress is indeed a significant factor affecting the egg production of hens. When hens experience stress, it can lead to hormonal changes that disrupt their reproductive cycles, ultimately resulting in decreased egg production. Factors contributing to stress can include environmental conditions (such as temperature fluctuations), overcrowding, handling practices, and changes in routine.

In contrast, inadequate feeding, poor lighting, and excessive breeding can also negatively influence egg production, but they are often perceived as external factors impacting hen health and productivity. While these factors are important in overall poultry management, stress frequently has a more immediate and profound effect on production levels since it can lead to a range of physiological issues, including the cessation of laying altogether. Proper management to minimize stress is crucial for optimizing hen performance and maintaining consistent egg production.
