How Many Eggs Does a White-Crested Polish Lay Per Year?
A White-Crested Polish hen lays about 150 medium white eggs a year — the Conservancy breed-page point, below the chart's 200+. Plus a flock formula.
A White-Crested Polish hen lays about 150 medium white eggs per year. That is the Livestock Conservancy breed page's point estimate, and it matches our breed data — not a consensus. The Conservancy's own 2026 comparison chart rates the breed Very Good at 200+, and Oklahoma State says around 200 or more. We plan on 150 because it is the only closed institutional figure; 200 is our High, not our Normal. What sets Polish apart is the crest: it decides vision, housing, and winter care more than the Year-1 count does. It can fall over the eyes and impede vision, leaving birds prone to aerial predation and easily startled. Crests also waterlog and can freeze in icy weather, so a dry, ventilated coop matters more than extra light. Hens rarely go broody — plan on an incubator for chicks. The breed sits at Recovering on the Conservancy's Conservation Priority List, and Meyer lists laying maturity at 20 to 24 weeks.

Production ranges
| Scenario | Annual eggs | Avg / week | Avg / day | When this happens |
|---|---|---|---|---|
| Low | ~100 | ~1.9 | ~0.27 | Ornamental and show-bred, crest-first stock, Year 1 |
| Normal | ~150 | ~2.9 | ~0.41 | Typical backyard hen, Year 1 to 2, dry coop, layer feed, natural daylight |
| High | ~200 | ~3.8 | ~0.55 | Well-bred laying strain, Year 1, well managed |
The Normal row is the most realistic starting point for planning. It assumes a healthy first or second year hen on layer feed, in a dry, ventilated coop, whose crest is not costing her the laying year through chilling or predation. About three eggs a week across the year is the honest planning figure — not the daily egg a production hybrid will give you, and not the 200+ the chart prints without closing the top.
150 sits below two institutional sources, and that is the finding, not a rounding error. The breed page says about 150. The Conservancy’s own Heritage Chicken Breed Comparison Chart (2026) rates Polish Very Good at 200+, and Oklahoma State says around 200 or more. We take the breed page’s point estimate as Normal because it is the only closed institutional figure and it matches our breed data. The chart and OSU print 200 and then decline to close the top — that sets our High at 200 and forbids 225 or 250, the same call made on Cackle’s open-ended “200+” for Hamburg and the breed page’s “over 200” for Faverolles. A well-bred laying strain may well sit nearer 200. Our Normal is the conservative reading, not the institutional consensus.
By year, month, week, and day
| Time period | Low (~100/yr) | Normal (~150/yr) | High (~200/yr) |
|---|---|---|---|
| Per year | 100 | 150 | 200 |
| Per month (average) | ~8.3 | ~12.5 | ~16.7 |
| Per week (average) | ~1.9 | ~2.9 | ~3.8 |
| Per day (average) | ~0.27 | ~0.41 | ~0.55 |
| Dozens per year | ~8.3 | ~12.5 | ~16.7 |
A hen lays one egg every 24 to 26 hours at full production and skips days, so the daily average never reaches 1.0. For a White-Crested Polish the yearly average is pulled down mainly by which population you bought — crest-first ornamental stock versus a laying strain — and by whether a wet crest or a predator takes weeks out of the year. They almost never sit, so broodiness is not the lever. Counting on roughly three eggs a week per hen across the whole year is a sound planning rule.
The formula
Scale to any flock size:
Weekly eggs = Number of hens × 3.2 × Age Factor × Season Factor
The baseline of 3.2 is a White-Crested Polish hen’s weekly output at peak, chosen so the season-weighted year matches Normal rather than overshooting it. Meyer’s White Crested Black page publishes Weekly Production 2–4. We do not put 2–4 on the stats card. Two is the ornamental-stock neighbourhood (Low averages ~1.9 a week), not a peak; our formula peak is 3.2 and the High week is 3.8, so the card uses 3–4 as the peak band — the upper half of Meyer’s published range, not a silent narrowing of it. Adjust the baseline down with the factors below as the flock ages and the seasons change.
| Factor | Multiplier |
|---|---|
| Year 1 (peak) | ×1.00 |
| Year 2 | ×0.84 |
| Year 3 | ×0.66 |
| Year 4 | ×0.50 |
| Year 5 | ×0.38 |
| Spring / Summer | ×1.00 |
| Fall (Sept to Oct) | ×0.90 |
| Winter, no supplemental light | ×0.75 |
| Winter, 16-hr light schedule | ×0.95 |
Example: 6 hens × 3.2 × 0.84 (Year 2) × 0.75 (winter, no light) = ~12 eggs per week.
Why 3.2 reconciles with Normal. Run a constant peak baseline through a Year-1 season mix — about six months at ×1.00, two fall months at ×0.90, and four winter months at ×0.75 with no supplemental light — and you get roughly 46.8 peak-equivalent weeks. 3.2 × 46.8 ≈ 149.76, which rounds to the Normal figure of ~150. A baseline of 4 would imply about 187 for the year, 37 above Normal, and this breed almost never broods, so sitting spells cannot silently absorb the gap. The Conservancy’s late-season start is already inside the 150; do not drop the baseline further to count it twice. The age and season multipliers above are our standard curve, applied across the site rather than measured on Polish specifically. Use the egg production calculator to model your flock by age and season.
How production drops year over year
Production slides down gradually rather than stopping at a set age. The table applies the age factors to the Normal annual figure of ~150 eggs.
| Year | Per hen / year | Per hen / week | 6-bird flock / year | 6-bird flock / week |
|---|---|---|---|---|
| Year 1 (peak) | ~150 | ~2.9 | ~900 | ~17 |
| Year 2 | ~126 | ~2.4 | ~756 | ~15 |
| Year 3 | ~99 | ~1.9 | ~594 | ~11 |
| Year 4 | ~75 | ~1.4 | ~450 | ~9 |
| Year 5 | ~57 | ~1.1 | ~342 | ~7 |
Peak productive life on this page is two to three years — that is the window the stats block means, not lifespan. The Conservancy calls Polish persistent layers once they commence; that is a within-season claim, not the multi-year lifetime gift it gives Hamburgs. No source publishes a flatter numeric decline curve, so we keep the site-wide age multipliers. A common approach is adding a young pullet or two every other year, so the flock keeps producing while the older birds slow down.
Month by month (first-year hen)
The Conservancy says Polish tend to begin a bit late in the season, then lay persistently once they commence. That is a calendar trait, not an age-at-first-egg figure. The breed-page wording is “tending to begin a bit late in the season but persistently laying once they commence” — a participial clause, quoted exactly in Sources. January through March sit below a Hamburg-style climb; once she starts, non-sitters do not lose spring to broodiness, so the plateau holds. Winter still cuts on the standard factor — a waterlogged crest is a note, not a custom multiplier.
| Month | Natural light only | With 16-hr coop lighting | Notes |
|---|---|---|---|
| January | 8 | 10 | Has not commenced; light does not invent a late-season starter |
| February | 9 | 11 | Still late; watch ice in the crest from drinkers |
| March | 11 | 13 | Starting; days lengthening |
| April | 15 | 16 | Commenced; persistent once she starts |
| May | 17 | 17 | Peak month; non-sitters, so spring is not carved by broodiness |
| June | 16 | 16 | Holds; shade for a heat-tolerant, dry-climate bird |
| July | 15 | 15 | Plateau holds |
| August | 15 | 15 | Holds |
| September | 14 | 15 | Daylight shortening |
| October | 12 | 14 | Molt and shorter days |
| November | 10 | 14 | Wet-crest chill; dry ventilated coop |
| December | 8 | 13 | Minimum without lighting; frozen crest feathers in icy weather |
The natural-light column sums to the Normal figure of 150; adding a 16-hour schedule takes it to roughly 169. That is a real winter lift, smaller than the swing between ornamental stock at 100 and a laying strain at 200. If you do add light, start in early September before the days shorten, and aim for 14 to 16 total hours rather than leaving a bulb on overnight.
What changes the number
The single biggest lever on a White-Crested Polish annual total is which population you bought — crest-first ornamental stock versus a laying strain — followed by whether the crest costs her weeks through chilling, predation, or flock pecking. Broodiness barely registers.
Strain — ornamental versus production, and why Low is not about age
Hoover’s publishes 100 Small White Eggs/Year identically on White Crested Black, Golden, and Buff Laced. That is a deliberate figure, not a typo, and it is our Low. Hoover’s also files the breed under Purpose: Ornamental and calls the eggs Small, against the Conservancy’s Medium to Large. That is evidence of a different population — crest-first, show-bred stock in Year 1 — not a disagreement about the same hen. Age already has its own table above.
The tension is load-bearing and real. Skinner’s Chicken Breeds and Varieties (A2880) lists Use: “A strictly ornamental fowl.” The Conservancy still lists Use: Eggs and Characteristics: Excellent, persistent layers. Mississippi State P3036 files them among egg-laying birds and calls them excellent layers. The 2026 comparison chart Purpose cell is Eggs. No source publishes a numeric production-versus-show split like PoultryKeeper’s Orpington 100 to 180, so we do not manufacture one. The 100-to-200 spread is that split, named by cause rather than invented as two official bands.
Mile Four’s closed 150 to 200 corroborates that 200 exists as a commercial ceiling. It is not load-bearing on its own: hatchery closed tops were refused as Highs on Buff Orpington. The printed 200 on the Conservancy chart and at Oklahoma State, plus the open-ended rule forbidding anything above it, is what sets High.
No variety split
Our slug and display name are a shortening. The APA variety is White-Crested Black Polish, recognised in 1874; “White Crested” also covers White-Crested Blue, added in 1963. The Conservancy’s figures are breed-level and apply across varieties — the same framing used for Salmon Faverolles. In the United Kingdom the Poultry Club of Great Britain standardises the breed as Poland.
Hoover’s 100 is identical across three varieties. Cackle rates White Crested Black, Buff Laced, and Golden all “Good.” McMurray’s adjectives differ — White Crested Black “better,” Buff Laced “good,” White “fair” — and those are ordinal ratings, not counts. Meyer’s weekly peaks differ by product — 2–4 on White Crested Black chicks and White Crested Blue; 3–5 on Buff Laced hatching eggs and White Crested Black bantam — and are weekly, not annual. No institution publishes a variety-specific egg split. Do not invent one — the same call made on Light Sussex, Hamburg, Andalusian, Faverolles, and Orpington.
The crest — every consequence stays with its source
The crest is this breed’s distinguishing management fact. Keep the levels distinct.
Vision, startle, and aerial predation — institutional. The Conservancy breed page says the feathers can fall over the eyes and impede vision, leaving the birds prone to aerial predation; they are easily surprised and a bit nervous. The 2026 comparison chart notes a dense crest that obscures vision, “flighty when disturbed,” and vulnerability to predators. Skinner A2880 and Oklahoma State describe restricted vision and birds that are easily frightened. Mississippi State P3036 is specific about free range: the crest obscures vision, so they are at greater risk of predation, especially from aerial predators, if allowed to free range. That is an extension warning, not hatchery colour.
Talk as you approach — Conservancy, in its own words. “It is best to talk to them when you approach because with their crests, they may not know you are there and fly away.”
Ice in the crest from drinking water — Skinner, copied by Oklahoma State. Ice forming in crests from drinkers is a cold-weather problem those two sources name. It is not Conservancy wording.
Waterlogged crests, frozen feathers, dry ventilated coop — Conservancy breed page. Polish prefer a dry, warm climate and are heat-tolerant with shade. They do not do as well in cold because crests can become waterlogged and chill the bird, and crest feathers can freeze in icy weather. Keep them in a well-ventilated, dry coop. That is breed-specific institutional text, unlike Faverolles, where we refused to import general feathered-leg advice.
Space so birds do not pick crests — Skinner and Oklahoma State. Crest lice — Oklahoma State only. Skinner and OSU both say they need plenty of space to avoid damaging each other’s crests by picking. OSU adds that the crest is also susceptible of lice; Skinner’s Polish paragraph does not.
Elevated brooders — 2026 chart notes. Raising chicks in elevated brooders so they can see human activity better can make them more calm. That is a Conservancy chart note, not an extension bulletin.
Crest trimming — hatchery and keeper practice, not extension. No institutional source recommends trimming. Cackle’s Gail Damerow article says that if birds are not destined for the show circuit, trimming feathers away from the eyes with blunt-tip scissors would be kind and could be life-saving; not every Polish needs it. Meyer says they “may require crest trimming to help them see out from their gorgeous top knot.” Label both as hatchery and keeper practice. They are not an extension finding.
The skull — anatomy versus injury risk, and who says which. The Conservancy describes a bony prominence on the skull that supports the crest. That is anatomy, not a warning. The cerebral-hernia literature is a different class of source: Yoshimura et al. (2012) document cerebral hernia in crested Polish associated with crest formation; Tao et al. in Genes (2020) describe a partially membranous frontal bone, an irregular skull hole, and excessive cerebrospinal-fluid accumulation in crested birds with cerebral hernia. PoultryDVM warns that crested breeds with a vaulted skull can be injured by a single forceful peck, because the brain may be protected by only skin and feathers. Attribute those claims to the papers and the veterinary page, not to the Conservancy or Skinner. No extension source publishes a backyard head-injury warning. McMurray’s own Q&A, answering a customer about cranial hernia and over-selection for crest size, says they do not select for crest size and instead select for vigour, body size, and longevity.
Temperament — leave the field, carry the nuance
Our breed data marks temperament flighty. That field is a housing tag, not a temperament essay, and we are not changing it. The Conservancy’s own sentence is the nuance: “Calm, but flighty when disturbed.” The 2026 chart’s temperament cell says Docile; the same row’s notes say flighty when disturbed. Mississippi State calls them somewhat nervous and flighty. Meyer: Friendly, Flighty. Hoover’s: Gentle, Active, easily surprised. McMurray disposition “better,” free range “poor.” Talk before you touch; they fly; they do not see the fox. Changing the field to docile would file them next to a Cochin. The calm-until-startled reading belongs in this paragraph.
The 2026 chart rates owner experience Intermediate. Our breed data marks them not beginner-friendly. Crest care, predator risk, and startle are why.
Non-broody — plan to incubate
The Conservancy says Polish hens are non-sitters and rarely will go broody. The 2026 chart lists Non-Setters. Mississippi State: poor mothering instincts, rarely broody. McMurray: not at all likely. Cackle: Non Setters. Meyer: Broody: No. Practical consequence: if you want chicks, use an incubator or a broody of another breed. The upside for egg keepers is that sitting spells almost never remove weeks from the laying year.
Climate — dry and warm, with a hatchery echo
The 2026 chart says they can handle hot and cold, but not extremes. The breed page prefers dry and warm, heat-tolerant with shade, and weaker in wet cold because of the crest. McMurray rates heat excellent / best and cold poor, free range poor. We record climate tolerance as temperate on the breed profile — a compression of the chart’s “not extremes” plus the wet-crest warning, not an invented third climate. Keep the standard winter factor in the formula; put ice and waterlog in the month notes.
Age at first lay — hatchery window, no institutional date
No institutional source publishes an age at first egg for Polish. Meyer publishes Laying Maturity: 20–24 weeks on its White Crested Black page — an actual laying window, which is why the stats block uses 20–24 rather than narrowing it. McMurray lists 20 weeks to maturity, which is a maturity rating, not a first-egg age, the same distinction drawn on Hamburg, Faverolles, Andalusian, and Orpington. The Conservancy’s late-in-the-season line is about the calendar, not weeks from hatch.
Egg colour and size
Eggs are white and medium. The breed page says medium-to-large white; the 2026 chart says White, Medium to Large. McMurray and Cackle say medium. Hoover’s Small is the ornamental-population tell, not our size cell. We keep medium.
Weights, conservation status
Weights are clean across the Conservancy, Skinner, Oklahoma State, McMurray, and Cackle: about 4.5 lb hen and 6 lb rooster. The breed sits at Recovering on the Livestock Conservancy’s 2026 Conservation Priority List (poultry PDF). The breed page and the 2026 comparison chart both say Recovering as well — no document split of the Hamburg/Faverolles kind.
History that still shows up in the yard
Birds that look like Polish appear in Dutch and Italian paintings from the 1400s. Exact origin is unknown; possible routes include Central and Eastern Europe with Asian Mongols, or Spain to Holland in the late sixteenth century. Credit for refining colour patterns and crests goes to Dutch fanciers of the eighteenth century. Known as Poland, Tophat, and Paduan; Darwin classed crested fowl as Polish or Crested. They were popular in France for egg production, arrived in America between 1830 and 1840, and were widespread by 1850. The rise of the Leghorn from the 1850s through the 1890s pushed them into exhibition. APA: non-bearded White-Crested Black, Golden, Silver, and White in 1874; bearded Golden, Silver, White, and Buff Laced in 1883; non-bearded Buff Laced in 1938; non-bearded White-Crested Blue in 1963.
How White-Crested Polish compare
First-year production under normal backyard conditions. Figures are the ones used across this site’s breed profiles.
| Breed | Annual eggs | Egg color | Type | Vs White-Crested Polish |
|---|---|---|---|---|
| Polish (White Crested) | 150 | White, medium | Light ornamental layer | Baseline |
| Sebright | 80 | Cream, small | True bantam ornamental | Lower |
| Silkie | 100 | Cream, small | Bantam, broody | Lower |
| Cochin | 160 | Brown, medium | Heavy heritage | Higher |
| Andalusian (Blue) | 165 | White, large | Light Mediterranean | Higher |
| Salmon Faverolles | 180 | Tinted cream, medium | Dual-purpose heritage | Higher |
| Hamburg | 200 | White, medium | Light heritage layer | Higher |
| Buff Orpington | 220 | Brown, large | Heritage | Higher |
The honest verdict: a White-Crested Polish is a light ornamental white-egg layer at about 150 a year — above a Silkie, a little below a Cochin, well below a Hamburg or a Buff Orpington, and not a bird you keep for maximum eggs. What she adds is the crest, a Recovering conservation status worth supporting, and a non-sitting laying year once she commences. She is not a free-range beginner bird, not a mother hen, and not a wet-cold specialist. For a keeper who wants a showy white-egg hen and will keep the crest dry, talk as they approach, and house her out of aerial-predator range, she earns her keep. For eggs per square foot, look at a Leghorn or a hybrid instead.

Frequently asked questions
How many eggs does a White-Crested Polish lay per year?
About 150 medium white eggs. That is the Conservancy breed-page point estimate and our Normal. The 2026 comparison chart says Very Good at 200+; Oklahoma State says around 200 or more. Those open-ended figures set our High at 200 and forbid anything above it. They are not our planning number.
How many eggs does a White-Crested Polish lay per week?
Three to four at peak on the stats card. Meyer publishes 2–4 on White Crested Black; we do not reprint the 2, because that floor is the ornamental Low (~1.9 a week averaged), not a peak. Formula peak is 3.2 and the High week is 3.8, so the card is 3–4. Averaged across a full year, plan on about three.
When do White-Crested Polish start laying eggs?
No institutional source publishes a first-egg age. Meyer lists laying maturity at 20 to 24 weeks; that hatchery window is what the stats block uses. McMurray’s 20 weeks to maturity is a maturity rating, not a first-egg date. The Conservancy’s late-in-the-season line is about the calendar, not weeks from hatch.
Do White-Crested Polish go broody?
Almost never. The Conservancy says non-sitters and rarely broody; the 2026 chart lists Non-Setters; Mississippi State, McMurray, Cackle, and Meyer agree. Plan on an incubator or another breed if you want chicks.
How many eggs will 6 White-Crested Polish hens lay per year?
Roughly 900 in a typical first year, with a realistic spread of about 600 to 1,200 depending on whether you bought ornamental or laying-strain birds, whether the crest stays dry, and winter light. Run your own numbers with the egg production calculator.
Do White-Crested Polish lay eggs in winter?
Not as a cold-weather layer. The Conservancy says they prefer a dry, warm climate and “do not do as well in cold weather” because crests waterlog and freeze. December and January are the two lowest months on this page (8 eggs) — lower than the winter floor on the other guides in this series. Persistence here means they keep laying once they have commenced, not that they lay through cold. A dry, ventilated coop is Conservancy breed-page guidance, not a custom winter multiplier.
What color and size are White-Crested Polish eggs?
White and medium. Breed page and 2026 chart say medium to large; McMurray and Cackle say medium. Hoover’s Small describes ornamental stock, not our size cell.
Do I need to trim the crest?
No institutional source says so. Cackle’s Gail Damerow article recommends trimming for birds not destined for show; Meyer says they may require it. Hatchery and keeper practice, not extension.
Are White-Crested Polish good for beginners?
Usually not as a first pet in an open run. Our breed data marks them not beginner-friendly; the 2026 chart rates Intermediate. Crest vision, aerial predation, and wet-cold care are the reasons. Fine for a keeper who will house them securely and talk as they approach.
Is “White-Crested Polish” the APA variety name?
It is a shortening. The 1874 APA variety is White-Crested Black; White-Crested Blue was added in 1963. Conservancy egg figures are breed-level. The UK name is Poland.
Sources
The Livestock Conservancy is the primary institutional source for Polish egg figures, and it publishes two documents that do not agree on the count — both are cited below rather than collapsed into one. Cooperative extension and Oklahoma State sit next. UK naming sits with the Poultry Club. Hatchery pages are ranked below those and labelled as commercial guidance. The skull-injury material is scientific and veterinary, not extension. Each source is named for the specific claim it supports.

Two classes of source were checked and deliberately not used: aggregator and content-farm breed pages that restate Conservancy or hatchery ranges without primary data, and seller copy that recycles the same figures. For health concerns about your flock, consult a licensed poultry veterinarian.
