When Do Chickens Start Laying Eggs? What to Expect and How to Help
You’ve raised your pullets from fluffy day-old chicks, kept them warm, kept them fed, cleaned the brooder more times than you want to count — and now you’re checking the nest boxes every morning hoping for that first egg. It’s one of the most exciting moments in backyard chicken keeping. And one of the most common questions new flock owners ask is: when do chickens start laying eggs?
The honest answer is that when chickens start laying eggs depends on the breed, the time of year, and a handful of things happening inside your pullet that you can nudge but can’t rush. Here’s what’s actually going on, what a realistic timeline looks like, and a few simple things you can do to support your hens as they approach point-of-lay.
When Do Chickens Start Laying Eggs? The Typical Age Range
Most chickens start laying eggs somewhere between 18 and 24 weeks of age. That’s roughly four to six months from hatch day. But that range is wide for a reason — breed matters a lot.
Light production breeds bred specifically for egg output tend to hit the earlier end of that window. Heritage breeds, dual-purpose birds, and naturally broody breeds often take longer and may not lay consistently until closer to six months or beyond.
A rough breakdown by breed type:
- Leghorn, Golden Comet, ISA Brown: Often as early as 16–18 weeks
- Plymouth Rock, Rhode Island Red, Australorp: Typically 20–22 weeks
- Sussex, Wyandotte, Orpington: Often 22–26 weeks
- Silkie, Cochin, Brahma: Sometimes 26–30+ weeks
If you’re not sure what breed you have or you’ve got a mixed backyard flock, budgeting for somewhere around 20–24 weeks is a reasonable middle ground.
Signs a Pullet Is Close to Laying Eggs
You don’t have to guess blindly. Before chickens start laying eggs, hens telegraph point-of-lay with a few reliable signs a week or two before the first egg appears.
Her comb and wattles will redden and swell. This is one of the clearest signals. A pullet with a pale, flat comb is still growing. A pullet with a bright red, plump comb is close to ready. If your breed has a pale or rose comb, watch for the deepening of color rather than dramatic size change.
She’ll start visiting the nest box. Pullets often inspect, sit in, and rearrange nest boxes for days or even a week before laying their first egg. This is normal nesting behavior, not a false alarm.
She’ll squat when you approach her. The submissive squat — where a hen lowers her body and spreads her wings slightly when you reach toward her — is a sign her hormones have kicked in. It happens because hens instinctively adopt this posture for a rooster, and your hand triggers the same response. Once you see the squat, eggs are usually days away.
Her pelvis will widen. You can gently check this by placing two fingers between the two pelvic bones just below the vent. In a young non-laying pullet, the bones are close together. As she approaches lay, the gap opens to allow an egg to pass — typically wide enough for two fingers side by side.
Why Your Hen Might Be Late to Start Laying Eggs
If your pullets are past the age window where chickens start laying eggs and you’re still not seeing anything in the nest box, a few things could be slowing them down.
Daylight length. Hens need roughly 14–16 hours of light per day to trigger and maintain laying. Pullets that hit maturity in fall or early winter may delay their first lay until days get longer in spring. This is completely natural and not a sign anything is wrong.
Stress or disruption. Moving to a new coop, introducing new flock members, predator scares, or a change in their daily routine can delay laying. Hens are creatures of habit. Keeping their environment calm and consistent in the weeks leading up to point-of-lay helps.
Feed quality. Pullets need to be on a proper layer feed — or a grower feed transitioning to layer — with adequate calcium and protein. A diet that’s too low in protein or calcium can delay the start of laying and affect egg quality once they do start.
Illness or parasites. Mites, lice, worms, or respiratory illness can all suppress laying. If your birds look otherwise healthy and are simply late, feed and light are usually the first place to look. If they seem lethargic, are losing feathers out of season, or have other symptoms, a health check is worth doing.
What the First Eggs Look Like When Chickens Start Laying Eggs
Don’t expect perfection right away. When chickens start laying eggs, the first few are often small, misshapen, or off in some way. You might get a tiny wind egg with no yolk, a soft-shelled egg, a double yolk, or an egg with a wrinkled shell. All of this is normal.
It takes most hens a few weeks to settle into a regular laying pattern. Their reproductive system is calibrating — think of the first two to four weeks as the warm-up period. By the time they’re two to three months into laying, most hens are producing regular, well-formed eggs on a fairly predictable schedule.
How to Support Pullets Before Chickens Start Laying Eggs
You can’t rush the point at which chickens start laying eggs, but you can make sure nothing is holding it back unnecessarily.
Switch to layer feed at 18 weeks. Layer feed contains the extra calcium pullets need to form strong eggshells. Switching too early can stress developing kidneys, but making the switch around 18 weeks — or when you start seeing pre-lay signs — sets them up well.
Offer oyster shell free-choice. Even on a good layer feed, providing oyster shell in a separate dish gives hens a way to self-regulate their calcium intake. This is especially useful if some birds in your flock are laying and others aren’t yet.
Set up comfortable nest boxes. Aim for one nest box for every three to four hens. Line them with clean straw or shavings and place them lower than the roost bars so hens aren’t tempted to sleep in them. A quiet, dim nest box helps encourage use.
If days are short, add a light. If your pullets are maturing in fall or winter, a simple coop light on a timer adding a few hours in the early morning can help bridge the light gap and keep laying on schedule. Gradual increases work better than sudden bright exposure.
Keep the flock calm during the transition. Avoid major coop changes or new bird introductions in the weeks just before and after your pullets start laying. Let them settle into the routine.
How Breed Changes When Chickens Start Laying Eggs
The single biggest factor in when chickens start laying eggs is the breed you chose, and the spread between them is wider than most new keepers expect.
Production hybrids such as ISA Browns, Golden Comets and Hy-Line Browns are the earliest of all: bred for heavy output, these chickens start laying eggs commonly between 16 and 18 weeks.
Classic laying breeds — Leghorns, Rhode Island Reds, Australorps, Sussex — typically start between 18 and 22 weeks.
Dual-purpose and heritage breeds like Orpingtons, Wyandottes and Plymouth Rocks take longer, often 22 to 28 weeks, because they are putting energy into body mass first.
Large and slow-maturing breeds such as Brahmas, Cochins and Jersey Giants can take 28 to 40 weeks. If you bought a Brahma and are worried at week 24, you are simply early.
Bantams vary enormously and often start later than their size suggests.
The trade-off is real: the breeds in which chickens start laying eggs earliest also lay hardest and burn out fastest. A hybrid may give you 300 eggs a year for two years; a heritage bird gives you 180 a year for five or six.
Daylight, Season and Why Timing Slips
Breed sets the range in which chickens start laying eggs. Daylight decides where in that range a particular bird lands, and it is the reason two pullets of the same breed can start six weeks apart.
Chickens need roughly 14 to 16 hours of light a day before they start laying eggs and to lay consistently. This is why a pullet reaching maturity in October may hold off until February, while her sister hatched in January starts on schedule in June.
Autumn-hatched birds frequently wait for spring before chickens start laying eggs. Nothing is wrong with them, and there is no need to intervene.
Supplemental lighting works but is a genuine choice rather than an obvious improvement. It brings birds into lay sooner and keeps winter production up; it also uses up their finite follicle supply faster. Extension guidance from land-grant universities — Poultry Extension’s lighting guidance for small flocks is a good summary — recommends adding light in the morning rather than the evening so birds are not caught off the roost when it cuts out.
Stress delays everything. It is the commonest reason chickens start laying eggs later than the breed suggests. A move, a predator scare, a change of feed or a new bird in the flock can all push back when chickens start laying eggs by weeks.
Nutrition matters more than most people realise once chickens start laying eggs. Pullets should move onto a layer feed with around 16 percent protein and adequate calcium only as they approach lay — too early and the calcium load is hard on their kidneys.
How Long Do Hens Keep Laying Eggs?
Once chickens start laying eggs, most hens lay well for their first two to three years. Production tends to peak in year one, dip slightly in year two, and decline more noticeably by year three and beyond. Many backyard flock owners keep older hens well past peak production — they’re still useful birds, just less prolific.
Commercial operations typically replace flocks after 12–18 months. As a backyard keeper, you get to make your own call based on what your flock means to you.
Final Thoughts: The Wait for Chickens to Start Laying Eggs Is Worth It
That first egg — small, warm, slightly speckled, sitting in the corner of the nest box — is one of the genuinely satisfying moments in backyard chicken keeping. The weeks leading up to it can feel long, especially if you’ve been watching and waiting for a while.
Pay attention to the signs, keep the basics dialed in, and let your pullets do the rest. They’ll get there.
