Life span of hen is ____ years.
A
Correct answer
Explanation
15 years is correct. The average lifespan of a domestic chicken (hen) is typically 10-15 years, with well-cared-for hens living up to 15 years. Commercial layer hens are usually culled much earlier (around 18-24 months) when egg production declines. 5 years is too short for their natural lifespan, 10 years is reasonable but 15 represents their maximum potential lifespan, and 20 years is unrealistic.
