Chickens typically lay eggs about once every 24 to 27 hours, which means roughly one egg per day during their prime laying period

. However, the exact timing shifts slightly each day, so hens eventually skip a day after laying eggs consistently for a while

. Key points about how often chickens lay eggs:

• Frequency: Most hens lay nearly one egg per day during their peak production, which usually lasts for about two-thirds of the year

. This translates to about 5-6 eggs per week in good conditions

• Annual production: High-producing hens can lay up to around 250 to 300 eggs per year in their first year, with production gradually declining in subsequent years

• Factors influencing laying: Breed, age, season, diet, environment, and health all affect egg-laying frequency. Some breeds are bred for consistent laying, while others may stop or slow down during molting or shorter daylight periods in fall and winter

• Daylight impact: Hens need about 14-16 hours of light per day to maintain regular egg production. In shorter daylight months, egg laying naturally decreases unless supplemental lighting is provided

• Age: Hens start laying around 18 weeks of age, peak around 25-30 weeks, and then slowly reduce egg production over the years, often laying about 80% as many eggs in their second year compared to their first

In summary, a healthy, well-managed hen typically lays one egg every 24-27 hours, resulting in nearly one egg per day during peak laying periods, with natural breaks and seasonal variations affecting overall output.
