Chickens typically begin laying eggs around 18 to 22 weeks of age, depending on the breed and conditions
. They lay eggs almost daily during their peak production period, which usually lasts about 2 to 3 years
. After the first year, egg production gradually decreases each year. For example, a hen that lays about 250 eggs in her first year might lay around 200 eggs in her second year under ideal conditions
. By the third or fourth year, the number of eggs laid declines further, and hens may lay fewer eggs per week, eventually dropping to one egg a week or less as they age
. Most backyard hens lay eggs consistently for about 3 to 4 years, with the quality and size of eggs declining over time
. Commercial laying hens are often kept only 2 to 3 years because their egg production significantly decreases after that period
. In some cases, hens can continue to lay eggs for up to 5 to 10 years, but the frequency and quantity of eggs drop substantially after the first few years
. Supplemental lighting can help maintain egg production during shorter daylight months but does not prevent the natural decline with age
. Summary:
- Start laying eggs: 18-22 weeks old
- Peak egg-laying period: 2-3 years
- Consistent laying duration: about 3-4 years
- Egg production declines after 1 year, with significant drop after 2-3 years
- Some hens may lay sporadically up to 5-10 years
This means for practical purposes, chickens lay eggs most actively for about 2-3 years, with diminishing returns afterward
