The Lifespan of a Chicken
One of the most common questions I'm asked is "How long can a chicken live?"
Believe it or not, chickens have quite an impressive lifespan! The maximum age of a chicken is around 25 years. It's very rare for a chicken to live that long, however, because they are so vulnerable to predators and disease.
Due to their vulnerability, the average age of a backyard chicken is only about 3 or 4 years, although I feel that with special protection and care it would not be unreasonable to expect 7 or 8 years.
My oldest hen is a New Hampshire red/blue bantam cochin mix named Sarah. She is 11 years old and still laying.
