What is the average lifespan of a commercial layer hen?

The average lifespan of a commercial layer hen is typically around 2 years. This timeframe reflects the productive years these hens are most efficient in egg production. After two years, the hens generally experience a decline in egg output, making commercial operations often choose to replace them with younger birds to maintain high production levels. Therefore, while hens may live longer under less intensive management systems, 2 years represents a standard lifespan for commercial layers in the industry.

Other choices, while they may represent potential lifespans in different contexts (e.g., backyard hens may live longer), do not align with the production cycle and management practices of commercial poultry operations.
