When do chickens start laying eggs? Many pullets produce a first egg at roughly five to six months, but that range is not a deadline. Early-maturing laying breeds may begin sooner, while larger, heritage, or slow-maturing breeds may take longer.
A hen that stops laying because she remains persistently broody needs a separate management plan; see How to Break a Broody Hen.

Day length, hatch date, complete nutrition, health, stress, and individual development all influence timing. Watch the whole bird and her stage of maturity rather than changing feed or worrying based on the calendar alone.
Quick answer: Most pullets begin laying around 18 to 24 weeks, with substantial breed and individual variation. Signs include a larger red comb and wattles, squatting when approached, interest in nest boxes, wider pelvic spacing, and more purposeful nest-seeking behavior. Switch to layer feed according to the feed label and point-of-lay guidance, not simply because another bird of the same age laid first.
First-Egg Timing at a Glance
| Age or stage | What is usually happening | Owner’s priority |
|---|---|---|
| 0–8 weeks | Rapid chick growth; no reproductive signs expected | Complete chick starter, brooder safety, clean water |
| 8–16 weeks | Pullet growth and feather development | Appropriate grower/developer feed and steady development |
| 16–18 weeks | Some early strains approach point-of-lay; many birds are not ready | Prepare nests and monitor body condition and maturity |
| 18–24 weeks | Common first-egg window for many laying breeds | Follow feed-label transition guidance and watch for laying signs |
| 24+ weeks | Normal for many large, heritage, winter-maturing, or individual pullets | Review breed, season, nutrition, stress, parasites, and health |
This is a planning range, not a diagnosis. Breed standards, hatch date, body development, season, and health are more informative than comparing one pullet with the earliest bird in the flock.
The Typical First-Egg Timeline
The University of Minnesota Extension says hens begin laying at around six months of age. Commercial laying strains often mature earlier than heavy or ornamental breeds, and pullets reaching maturity during short winter days may delay production.
Treat any week range as an estimate. Two same-breed sisters can lay weeks apart while both remain healthy.
The University of Minnesota Extension’s pullet-raising guide places the transition to layer management around 18–20 weeks, while recognizing that development and feeding programs vary.
Breed Makes a Difference
Breeds selected for high egg production often reach point-of-lay earlier and lay more frequently during the first seasons. Large heritage, dual-purpose, or slow-maturing birds may invest more time in body growth.
Compare temperament, climate fit, egg size, and maturity in Best Egg-Laying Chicken Breeds rather than choosing by earliest first egg alone.
Early, Average, and Slow Maturity
Production-oriented hybrids and lighter egg breeds often mature toward the early end of the range. Many dual-purpose breeds are closer to the middle, while very large, heavily feathered, ornamental, or slow-growing heritage breeds may mature later. These are broad tendencies; an individual bird can fall outside the expected pattern.
| Influence | Possible effect on first lay | What to do |
|---|---|---|
| Breed or strain | Changes average maturity and production pattern | Use hatchery or breeder guidance for that line |
| Short natural days | May delay reproductive stimulation | Avoid abrupt lighting changes; prioritize healthy growth |
| Low body weight or poor uniformity | Bird may not be physically ready | Review complete feed, access, parasites, and health |
| Move or flock disruption | Stress may temporarily delay laying | Settle pullets into layer housing before expected lay |
| Illness or parasites | Diverts energy and slows development | Investigate symptoms and seek qualified help |
Signs a Pullet May Lay Soon
- Comb and wattles become larger and redder
- The pullet squats when approached or touched over the back
- She investigates nest boxes repeatedly
- Pelvic bones gradually widen as maturity approaches
- Vocalizations and flock status may change
- She spends time in a nest without sleeping there overnight
Observe Signs Without Repeatedly Handling the Bird
Comb color, nest interest, and squatting are useful clues, but none predicts the exact day. Pelvic spacing and abdominal condition are used professionally as part of a broader assessment; repeated or forceful handling by an inexperienced keeper can frighten or injure a pullet. Visual observation is usually sufficient for backyard planning.
A pullet that is bright, active, eating, growing, and maintaining normal droppings may simply need more time. A bird that is thin, pale, lethargic, isolated, breathing abnormally, or losing condition needs a health evaluation rather than more nest-box training.
Feed Through the Transition
Continue the complete grower or developer program until the product label’s transition point or laying begins. Layer feed contains much more calcium and is not the routine ration for young chicks or immature pullets.
Use Layer Feed vs. Grower Feed to plan the change. In a mixed-age flock, an appropriate all-flock ration plus separate oyster shell for active layers may be more suitable.
Penn State Extension’s laying-flock guidance supports an age-appropriate complete ration and clean water as the foundation for healthy development and production.
Layer Feed, Grower Feed, and Calcium
Layer diets contain substantially more calcium than chick or grower diets because active shell production requires it. Do not rush immature chicks onto a layer ration merely because an older flockmate has begun laying. Follow the manufacturer’s label, the birds’ age and development, and advice appropriate to your flock.
In a mixed-age flock, a nutritionally appropriate all-flock feed with oyster shell offered separately to laying hens is often easier to manage. Oyster shell is a calcium source, not grit, and it does not correct inadequate protein, energy, vitamins, or overall ration balance.
Introduce any feed change gradually when the product instructions allow, keep the old and new labels during the transition, and make sure timid pullets can reach feed and water. See Chicken Feeding Guide for the full life-stage overview.
Prepare Nest Boxes Before the First Egg
Install clean, quiet nests before pullets reach point-of-lay. A common guideline is one nest for every four to five hens. Keep nests lower than the highest roost so birds are less likely to sleep and soil them.
Place a clean rubber training egg in each nest if needed, and block unsafe laying corners. Review Best Chicken Nesting Laying Boxes.
What First Eggs May Look Like
Early eggs may be unusually small, double-yolked, soft-shelled, misshapen, or laid outside a nest while the reproductive cycle becomes consistent. Occasional odd eggs can occur in otherwise healthy pullets.
Repeated shell problems, blood, prolapse, straining, weakness, or appetite changes need veterinary attention. Do not keep adding calcium without checking the complete diet and the bird’s health.
Keep a First-Egg Record
- Record the date, approximate size, shell condition, and nest location.
- Do not assume which pullet laid it unless you observed her or have reliable identification.
- Collect eggs regularly so a hidden clutch or broodiness does not confuse the count.
- Note soft shells, repeated blood, straining, prolapse, appetite changes, or weakness.
- Expect an inconsistent schedule while the reproductive cycle becomes established.
A tiny first egg or an occasional shell irregularity can occur during the transition. Persistent abnormalities—especially when paired with discomfort or systemic illness—deserve veterinary guidance.
Why a Healthy Pullet May Start Later
Short day length, a late-season hatch, slower breed maturity, heat, cold, stress, a recent move, flock bullying, or inadequate feed access can delay laying. Illness and parasites can also affect development.
Confirm that the pullet eats a complete ration, maintains body condition, has clean water, and is not being driven from resources. Avoid artificial lighting changes without understanding their effect on immature birds.
The University of Minnesota Extension notes that daylight, breed, nutrition, age, and general management all influence egg production.
A Step-by-Step Late-Layer Check
- Confirm age and sex: Hatch dates may be estimates, and a misidentified cockerel will not lay.
- Check the breed or strain: Compare with reliable breeder information rather than a generic 18-week promise.
- Look for hidden eggs: Search sheltered corners, brush, bedding cavities, and under structures.
- Review complete nutrition: Confirm the correct ration, clean water, and equal resource access.
- Consider season and stress: Short days, recent moves, predators, heat, cold, and introductions can affect timing.
- Examine general health: Check body condition, droppings, breathing, activity, feathers, skin, and parasites.
- Seek qualified help: If maturity is substantially delayed or any illness signs appear, contact a poultry veterinarian or extension professional.
When to Investigate
If a pullet is well beyond the expected range for her breed, review sex identification, hatch date, nutrition, body condition, parasites, flock access, daylight, and health with a veterinarian or extension professional.
Seek prompt care for straining, tail pumping, penguin posture, prolapse, abdominal swelling, breathing difficulty, or weakness. Those are not normal signs of merely waiting for a first egg.

- Pullets are settled into their permanent housing before laying begins.
- The current grower or transition feed label has been reviewed.
- Plans for layer feed or mixed-age feeding are ready.
- Clean water is continuously available.
- Every pullet can reach resources without being driven away.
- A simple egg and health record is ready.
- A poultry veterinarian or extension contact is available if problems develop.
Frequently Asked Questions
Can a chicken lay before 18 weeks?
Some early-maturing birds can, but it is not a universal target. Do not force early production with feed or light changes.
Why is one pullet laying and the others are not?
Individual maturity varies even within a breed and hatch. Monitor body condition and health rather than comparing every bird to the first layer.
Do pullets need a rooster to start laying?
No. Hens lay without a rooster. A rooster is needed only for fertile hatching eggs.
When should I switch to layer feed?
Follow the feed label and point-of-lay directions. Many programs transition around 18 to 20 weeks or the first egg, but formulas differ.
Do all pullets in one flock begin laying together?
No. Even pullets of the same hatch and breed can mature weeks apart. Track body condition and health rather than trying to force the later birds to match the first layer.
Should I add artificial light to make pullets start sooner?
Do not use lighting simply to rush an immature bird. Light programs affect reproductive development and should be matched to age, body development, season, and management goals. Backyard keepers should obtain flock-specific guidance before changing day length.
Final Thoughts
Most pullets lay their first egg when genetics, body development, nutrition, health, and day length align—not when a calendar reaches a particular week. Prepare the nests and feeding plan early, watch for maturity without overhandling, and give healthy late starters time. Investigate the bird, environment, and ration when development or behavior looks abnormal.
