When Do Chickens Start Laying Eggs? A Complete Timeline by Breed & Age

If you’ve been checking the nesting box every day like it’s a mailbox on Christmas Eve, you’re not alone. Waiting for that first egg is one of the most exciting (and nerve-wracking) parts of raising backyard chickens. The good news? There’s a very predictable timeline behind it, and once you know what to look for, you’ll be able to guess the big day almost to the week.

The Short Answer: Average Age Hens Start Laying (18–24 Weeks)

Most hens start laying eggs between 18 and 24 weeks old, which is roughly 4.5 to 6 months of age. This is the point where a young hen, called a pullet, has finished most of her physical growth and her reproductive system matures enough to begin producing eggs regularly.

That said, “average” is doing a lot of work in that sentence. Some breeds are speedy and start laying at 16 weeks. Others, especially larger or ornamental breeds, might take closer to 28–30 weeks. Season, nutrition, and even the individual bird’s personality all play a role. If your flock is somewhere in this window, you’re right on track.

Egg-Laying Timeline by Popular Backyard Breed

Breed is one of the biggest factors in determining when your hens will start laying. Here’s how some popular backyard breeds typically compare:

• Leghorn: 16–18 weeks — one of the earliest and most prolific layers
• ISA Brown / Golden Comet (hybrids): 18–20 weeks — bred specifically for early, consistent laying
• Rhode Island Red: 18–20 weeks
• Plymouth Rock: 20–22 weeks
• Australorp: 20–24 weeks
• Wyandotte: 22–24 weeks
• Orpington: 22–26 weeks
• Silkie: 26–30 weeks — slower to mature and lay less frequently overall
• Brahma: 28–34 weeks — a large, slow-maturing breed worth the wait

If you’re still choosing breeds and want eggs sooner rather than later, hybrids like ISA Browns or standard breeds like Rhode Island Reds and Leghorns are considered some of the best egg laying breeds for beginners. They’re reliable, hardy, and forgiving of small mistakes while you learn the ropes.

6 Physical & Behavioral Signs Your Hen Is About to Lay

Wondering how to tell if a hen is about to lay? Nature actually gives some fairly obvious hints in the days and weeks before that first egg. Here are the signs a chicken will start laying soon:

• Comb and wattle change: They become larger, fuller, and turn a deeper, brighter red.
• Squatting behavior: When you approach or reach toward her, she crouches down and slightly spreads her wings — this is a mating/laying reflex.
• Nesting box curiosity: She starts investigating, sitting in, or rearranging bedding in the nesting boxes, even without laying yet.
• Increased vocalization: Some hens become noticeably chattier or make a distinct “egg song.”
• Appetite increase: Egg production takes energy and calcium, so you may notice her eating more.
• Wider, redder vent: The area beneath her tail becomes moist, pink, and slightly enlarged compared to its drier, paler appearance before maturity.

If you’re spotting two or three of these signs together, it’s a strong bet you’ll find an egg within the next one to two weeks.

What Affects When a Chicken Starts Laying (Season, Light, Nutrition, Stress)

Genetics set the baseline, but real-world conditions can speed things up or slow them down considerably.

Daylight: Hens need roughly 14–16 hours of light per day to trigger consistent laying. Pullets maturing in late fall or winter, when days are short, may delay laying until spring, even if they’ve hit the right age.

Nutrition: A pullet that isn’t getting enough protein, calcium, or overall calories will mature more slowly. Quality feed matters more than most people expect.

Stress: Predator scares, sudden environment changes, moving to a new coop, or aggressive flock mates can all delay the onset of laying or cause a hen to pause after she’s started.

Body weight: Hens need to reach a minimum body weight before their bodies prioritize egg production. Underweight pullets will lag behind, regardless of age.

Season: Chickens hatched in early spring often start laying right on schedule in late summer. Chickens hatched in late summer or fall may not lay until the following spring due to shortening daylight.

How to Prepare Your Coop and Nesting Boxes Before the First Egg

It’s worth setting up your nesting boxes several weeks before you expect the first egg, so hens have time to get comfortable and develop the habit of laying in the right spot rather than hiding eggs around the yard.

Whatever coop style you choose, the key is having at least one nesting box per 3–4 hens, filled with soft bedding, in a quiet, dim corner — this is exactly how we design the nesting compartments in Peggy’s Happy Chickens coops, so new layers have a calm, predictable spot to settle into the habit.

A few extra tips: keep nesting boxes away from high-traffic areas or the roosting bars, add a golf ball or fake egg to “show” hens where to lay, and check boxes daily so eggs don’t sit too long or encourage broodiness before you’re ready for that.

What to Feed Pullets to Support Healthy Egg Development

Feed should shift as your flock approaches laying age. Here’s a simple breakdown:

• 0–8 weeks: Starter feed with 18–20% protein to support rapid growth
• 8–18 weeks: Grower feed with slightly lower protein, balanced for steady development
• 18+ weeks (or first sign of laying): Layer feed with added calcium to support strong eggshell formation

Switching to layer feed too early can strain a young pullet’s kidneys with excess calcium, so time the transition to when you see real signs of laying approaching, not just by age alone. Offering crushed oyster shell on the side (rather than mixed into feed) lets each hen regulate her own calcium intake as needed.

My Chicken Is Past 6 Months and Still Not Laying — What Now?

If you’re asking “why isn’t my chicken laying eggs yet” and she’s past the 24-week mark, don’t panic just yet. First, double-check her breed’s typical timeline — slower breeds like Brahmas or Silkies can take closer to 7–8 months. Next, consider the season; a pullet maturing in November may simply be waiting for longer daylight in spring.

Also rule out stress, illness, poor body condition, or being low in the pecking order, which can all delay laying. If she’s well past her breed’s expected window, appears healthy, active, and at a good weight, but still isn’t laying by 30 weeks, it may be worth consulting a poultry vet to rule out reproductive issues. In most cases, though, it really is just a matter of a few more patient weeks.

What to Expect With the First Few Eggs (Size, Shape, Frequency)

First eggs are often small, sometimes called “pullet eggs,” and may be oddly shaped, have thin or wrinkled shells, or occasionally arrive without a yolk. This is completely normal as her laying system calibrates itself.

Frequency also starts slow. A hen might lay every other day at first, gradually working up to her breed’s typical rate over several weeks. Within a month or two, most healthy layers settle into a fairly predictable rhythm.

Frequently Asked Questions

Do chickens lay eggs every day once they start?

Not quite. Most hens lay an egg roughly every 24–26 hours during their peak, which means most breeds average 4–7 eggs per week rather than one every single day. Production naturally slows in winter or during molting.

Can you eat the first eggs a chicken lays?

Yes, absolutely. Pullet eggs are perfectly safe and edible, just smaller than what you’ll get once she’s fully mature. Many keepers enjoy collecting these tiny first eggs as a fun milestone.

Do chickens need a rooster to lay eggs?

No. Hens will lay eggs on a regular schedule with or without a rooster present. A rooster is only necessary if you want those eggs to be fertilized and hatch into chicks.

Why did my hen stop laying after she just started?

This is common and usually caused by stress, a change in daylight length, moving to a new coop, illness, or the start of a molt. Give her a few weeks in a calm, well-fed environment, and laying typically resumes on its own.

What time of day do chickens usually lay their eggs?

Most hens lay in the morning to early afternoon, influenced by daylight and their internal laying cycle. It’s rare for a hen to lay an egg after dark, so an evening coop check is usually safe to skip.
