When Will My Chicken Lay Her First Egg?
Her comb is getting redder. She keeps wandering through the nesting boxes. Maybe she even squats when you reach toward her. So when is that first egg actually coming?
Enter her hatch date or age and breed to get an estimated first-egg window — not a pretend appointment — plus her current stage and what to prepare next.

Quick Answer
Many pullets begin laying somewhere around 18–24 weeks, while some backyard breeds may take closer to 5–7 months or longer. Production-focused breeds and hybrids may mature relatively early. Larger, slower-maturing, ornamental or heritage breeds may begin later.
Enter her hatch date or current age, breed, and optionally daylight and signs, and the calculator estimates:
- Her current age and development stage
- Her breed's expected first-egg age range
- The earliest and later calendar dates of that window
- Whether she's approaching, inside or past the window
When Do Chickens Start Laying Eggs?
A common general range is about 18–24+ weeks, but there's substantial variation. Penn State guidance places well-managed pullets around the 20-week point (Penn State Extension), while Utah State describes backyard maturity more broadly at around 5–7 months (USU Extension).
Both can be true. A production-focused bird may begin earlier; a large, slower-developing heritage breed may begin later. That's why the calculator uses breed-specific ranges and a broader fallback — about 18–26 weeks — when the breed is unknown.
What Age Do Chickens Lay Their First Egg?
For many breeds, roughly 5–6 monthsis a useful planning expectation — but it shouldn't become a deadline.
- Earlier-maturing birds
- Some production breeds and hybrids begin around the early end of the normal range.
- Typical backyard layers
- Many begin somewhere around 18–24 weeks.
- Slow-maturing birds
- Large, ornamental or slower heritage birds may take 6–7 months or longer.
What matters most is breed + individual development + season.
Why Does Breed Affect First Lay?
Breeds were developed toward very different goals. A Leghorn-type production bird has been selected heavily for egg production, early maturity and feed efficiency. A Brahma has historically been selected for giant body size, dual-purpose utility and cold adaptation — and slower development. They shouldn't be expected to mature on the same schedule.
The calculator reads each breed's first-lay range from the same breed data that powers the Egg Production Calculator, so a Buff Orpington never gets one range here and a different one somewhere else.
Which Chicken Breeds Start Laying Earlier?
Broadly, highly production-selected breeds and hybrids — think Leghorns, ISA Browns and Golden Comets — often mature earlier than giant, ornamental or slower-developing heritage types like Brahmas and Silkies.
We deliberately don't publish a precise ranking. Strain and hatchery line matter as much as the breed name, and the calculator should only display precision we can defend.
Do Larger Chicken Breeds Start Laying Later?
Often, slower-growing large breeds mature later than lightweight production breeds. But body size alone isn't a formula — Brahmas don't simply get “+4 weeks because large.” Their window comes from breed-specific expectations, not a size multiplier.
Does Daylight Affect When Chickens Start Laying?
Yes. Day length is closely tied to reproductive activity in chickens, and laying hens generally need substantial daily light to maintain strong production (University of Minnesota Extension). A pullet reaching maturity in spring experiences a very different light environment from one reaching the same age in late fall.
That's why the calculator asks about daylight — but uses it as context, not exact date arithmetic. Nobody can honestly say that November light adds exactly 11 days.
Do Chickens Start Laying in Winter?
They can. A pullet doesn't automatically wait until spring just because December arrives — but short natural days can delay the start of laying in some birds. If her estimate says 20–24 weeks and she reaches 20 weeks in December, don't panic if the first egg doesn't appear right away.
What Are the Signs a Chicken Is About to Lay?
- Comb and wattles getting larger
- Hormonal changes make these features more developed.
- Comb and wattles becoming redder
- A pale juvenile comb may turn a more intense red.
- Pelvic changes
- The body prepares for egg production.
- Nest-box interest
- She may begin inspecting nesting spots.
- Squatting
- Some pullets crouch when you reach toward them as they mature.
- Behavior changes
- Some become more vocal or restless.
Penn State discusses comb and wattle development and pelvic changes as pullets approach production (Penn State — Preparing Pullets). No single sign gives you a countdown — use several together.
Why Hasn't My 6-Month-Old Chicken Started Laying?
Six months can still be completely normal depending on breed, season and individual development. Review:
- Breed — is she a slow-maturing type?
- Daylight — did she reach maturity during short winter days?
- Nutrition — is she getting an appropriate balanced diet?
- Body condition — is she growing normally?
- Hidden nests — behind the feed bin, under a bush, in the hay pile, behind the mower.
- Health — does she otherwise look well?
A late first egg by itself isn't a diagnosis. If delayed laying comes with weight loss, lethargy, poor appetite, breathing problems, unusual droppings or other signs of illness, contact a poultry-savvy veterinarian or your local Extension office. For more causes, see why chickens stop laying eggs.
When Should I Put Out Nesting Boxes?
Don't wait until the morning of the first egg. Have nest boxes installed and accessible during the pre-lay stageso pullets have time to get familiar with them. Penn State recommends preparing birds and laying housing before production begins. We'd rather have boxes ready a little early than find the first egg under the roost.
For dimensions and placement, see Chicken Nesting Boxes: Size, Dimensions, How Many You Need & Where to Put Them.
When Should Pullets Start Layer Feed?
Different poultry rations have different manufacturer instructions, so don't take one universal age from an internet article. As pullets approach point of lay, review your grower/layer feed directions and prepare for the transition. The calculator reminds you to prepare — it won't override your feed formulation by declaring “Week 16 = switch now.”
What Are First Eggs Like?
Often smaller. Young pullets may initially lay eggs below their eventual mature size, and the first several weeks can be a little inconsistent. Eggs may occasionally be oddly shaped, yolkless or double-yolked (Poultry Extension — Avian Female Reproduction). That doesn't mean every first egg will be strange — many are perfectly ordinary, just small.
A normal, clean egg from a healthy pullet can generally be used like any other chicken egg. Egg size usually increases as laying becomes established.
Do Chickens Need a Rooster to Start Laying?
No. Hens don't need a rooster to mature, ovulate or lay eggs. A rooster is only necessary if you want fertilized eggs capable of developing into chicks — and if that's next, the Hatch Date Calculator maps out the 21 days.
The Bottom Line
For many pullets, roughly 18–24+ weeks is a useful starting expectation. But the real answer depends on breed, strain, development, daylight, season, nutrition, health and the individual chicken.
So the useful question isn't “what exact date will she lay?” It's “what is her realistic first-egg window — and is she showing signs she's getting close?” When the first egg finally appears, record it, take the picture, send it to everyone who's heard about this chicken for five months — and then move on to the next question with the Egg Production Calculator.
First Egg Calculator FAQ
When do chickens start laying eggs?
Many chickens begin laying around 18–24 weeks, while some breeds may take closer to 5–7 months or longer. Breed, season, daylight, development and individual variation all matter.
What age do hens lay their first egg?
A common planning range is around 5–6 months, but some start earlier and slower-maturing breeds may begin later.
Can chickens start laying at 16 weeks?
Some very early-maturing birds may begin unusually early, but 16 weeks is earlier than the typical range for many backyard breeds.
Is 20 weeks normal for a first egg?
Yes. Around 20 weeks falls within a common point-of-lay range for many pullets under good conditions.
Why is my 6-month-old chicken not laying?
Possible explanations include a slower-maturing breed, individual variation, shortening daylight, nutrition, stress, hidden laying locations or health issues. Six months is not automatically abnormal for every breed.
What are the signs a chicken is about to lay?
Common signs include a larger, redder comb and wattles, pelvic development, nesting-box interest, squatting behavior and changes in vocalization. No single sign provides an exact countdown.
Does squatting mean a chicken will lay soon?
It can indicate sexual maturity, but it does not reliably predict the exact number of days until the first egg.
Do chickens start laying later in winter?
They can. Short natural daylight can delay production in pullets reaching maturity during fall and winter.
Do Buff Orpingtons start laying later than Rhode Island Reds?
Breed and strain influence maturity. The calculator uses breed-specific ranges rather than assuming one breed always matures later based only on body size or reputation.
When should I open the nesting boxes?
Have nest boxes accessible during the pre-lay stage, before you expect the first egg.
When should pullets start layer feed?
Follow the directions for the feeding program you're using. As pullets approach point of lay, review the appropriate transition rather than relying on one universal age.
Are first eggs safe to eat?
Normal clean eggs from healthy pullets can generally be used like other chicken eggs. The first eggs may simply be smaller or somewhat irregular.
Does a hen need a rooster to lay her first egg?
No. A rooster is not required for egg production — only for fertilized eggs that can develop into chicks.
