When Do Hens Start Laying and How Often Do They Lay?

The question everyone with a new coop or a batch of chicks asks most is: "When will these hens start laying, and how many eggs a day will I get?" The answer depends on breed, season, light and nutrition. This guide explains clearly at what age hens start laying, how often they lay, what determines the yield, and whether you need a rooster for eggs.

At What Age Do Hens Start Laying?

Most hens lay their first egg at 18-22 weeks old (about 5-6 months). This varies noticeably by breed:

• Commercial hybrid layers (Lohmann, ISA Brown) are earliest: 16-18 weeks.
• Light layer breeds (Leghorn) 18-20 weeks.
• Heavy and dual-purpose breeds (Brahma, Orpington, Sussex) later: 24-28 weeks.

Signs that laying is near: the comb and wattles reddening and growing, starting to explore the nest, and the squat (crouch) behavior when touched. Choosing the right breed is the basis of yield — details in our layer vs meat breed selection guide.

How Often Do Hens Lay?

A good laying hen at peak lays almost every day — 5-6 eggs a week. Because forming an egg takes about 24-26 hours, it's "an egg most days" rather than a full egg every single day; a day is skipped now and then. Yield depends on breed:

Type / breed	Eggs/year (approx.)
Hybrid layer	300-330
Leghorn	280-320
Rhode Island Red / Australorp	250-300
Sussex / Plymouth Rock	200-250
Ornamental / broody breeds (Silkie etc.)	100-120

What Determines Egg Yield?

• Daylight: Hens need 14-16 hours of light a day to lay. On short winter days the yield drops or stops; adding morning/evening light in the coop to make the day 14-16 hours keeps laying going.
• Nutrition: Layer feed (16-18% protein) and extra calcium (oyster shell/grit) for shell quality are essential. Calcium deficiency leads to thin/cracked shells and lower yield.
• Age: Yield peaks in the first 1-2 years and declines gradually every year after. A hen lives long but lays less and less.
• Molt: Usually in autumn hens go into their annual feather change and pause laying for a few weeks during it; this is normal.
• Broodiness: A broody hen stops laying. If you want eggs, pick a non-broody breed; if you want to hatch, see our natural incubation with a broody hen article.
• Stress, heat and illness: Extreme heat, overcrowding, fear of predators or illness quickly lower the yield.

Do You Need a Rooster for Eggs?

No. Hens lay even without a rooster — but those eggs are infertile (no chick will hatch), they're only table eggs. A rooster is only needed if you want hatching (fertile) eggs. For eating eggs you don't need a rooster in the flock. For fertile eggs and rooster ratio, see our fertility guide.

How Many Years Do Hens Lay?

A hen's most productive period is the first 2-3 years. After that she keeps laying but noticeably less each year; after 5-6 years old it becomes very sparse. Commercial operations renew the flock every 1.5-2 years for this reason; in backyard flocks, hens are often kept as pets even as they age.

Nest Boxes and Egg Collection

• Provide one nest box per 3-4 hens; keep it dim, calm and clean. Hens lay where they feel comfortable.
• Collect eggs once or twice a day; nest cleanliness matters for both egg hygiene and delaying broodiness.
• If you're saving hatching eggs, the storage conditions differ — see the egg selection and storage guide.

The Most Common Mistakes

• Expecting eggs from too young a hen (before 5 months).
• Not adding supplemental light in winter and panicking when yield drops (short days are natural).
• Not providing calcium and getting thin shells and low yield.
• Mistaking the molt pause for illness.
• Keeping a rooster unnecessarily for table eggs.

Hens starting to lay is also the start of the incubation and chick-rearing cycle. You can track hatching eggs in the KuluçkaTakip app and learn the top-laying breeds from our breed selection guide.
