![]() She will then skip a day or more before laying another egg. Eventually the hen will lay too late in a day for ovulation to be signaled. ![]() It takes 26 hours for an egg to fully form (white and shell added), so a hen will lay an egg later and later each day. A hen ovulates a new yolk after the previous egg was laid. Ovulation (release of the yolk from the ovary) occurs every 24 – 26 hours regardless of fertilization (so a rooster is not needed). Using a timer and a 60-watt incandescent bulb, add light to the morning and late afternoon but allow hens to naturally roost in the evenings with the setting sun. Egg production may continue during the spring, fall, and winter when artificial light is supplemented to provide 14 -16 hours of light. Maximum egg production is reached during summer days with 16 hours of daylight. The hen’s ovulation is stimulated by the length of the day. When do hens begin to lay eggs?ĭuring ideal day length (14-16 hours of light) and with adequate nutrition, housing, and management, hens (depending on breed) should begin producing eggs when they are18- 22 weeks old. To keep a small flock producing, owners should plan to retire old hens and add young hens (pullets) every 2-3 years. Most commercial layers are kept for 2-3 years as their egg production decreases after this time. The level of egg production, egg size, and shell quality decrease each year. Hens may live in backyard flocks for 6-8 years, and most flocks will produce eggs for 3-4 years. English | Spanish | Hmong Lifespan of a hen
