What is the typical lifespan of a commercial layer?

The typical lifespan of a commercial layer is generally around 75 to 100 weeks. During this time, hens are most productive, laying an optimal number of eggs from about 20 weeks of age until they reach their peak production around 30 to 40 weeks of age. After this peak, egg production gradually declines.

This lifespan is typically managed within the commercial egg industry to ensure that layers are productive while maintaining overall flock health and efficiency. After 75 to 100 weeks, layers are often replaced to ensure maximum egg production levels and to avoid the costs associated with lower-yielding hens. Recognizing this range is crucial for understanding poultry management practices, especially for those involved in egg production.
