The length of time a chicken lays eggs consistently depends on the breed, care, and overall health of the bird. Some chickens are known for their longevity in egg production:
Chickens That Lay Eggs the Longest
1. Heritage Breeds
Heritage breeds often lay eggs for several years, although their production may decline after the first 2-3 years. Examples:
Rhode Island Red: Lays consistently for 4-5 years or longer with proper care.
Plymouth Rock: Known for steady production over many years.
Sussex: Lays well into their later years, albeit at a slower rate.
2. Commercial Hybrids
Hybrids like the Golden Comet and ISA Brown are bred for high egg production in the first 1-2 years. However, their egg-laying tends to decline sharply after this period.
3. Long-Lived Layers
Some breeds, like Leghorns or Australorps, can lay reliably for about 4-5 years, with a gradual decline afterward.
