How Many Eggs Does a Speckled Sussex Lay Per Year?
A Speckled Sussex hen lays 180 to 250 eggs per year. Realistic ranges by strain and broodiness, a month-by-month breakdown, and a formula for any flock size.
A Speckled Sussex hen lays 180 to 250 eggs per year in a typical backyard setting. The biggest variable is broodiness: Speckled lines go broody more readily than the Light Sussex, and every broody spell pauses laying for about three weeks, which is what separates a 180-egg year from a 250-egg one. For a healthy first-year hen in a well-managed flock, the most realistic estimate is 210 to 240 eggs annually.

Production ranges
| Scenario | Annual eggs | Avg / week | Avg / day | When this happens |
|---|---|---|---|---|
| Low | ~180 | ~3.5 | ~0.49 | Heritage breeder line, frequent broody spells, older bird, or winter without light |
| Normal | ~220 | ~4.2 | ~0.60 | Hatchery-strain hen, Year 1 to 2, natural daylight, standard layer feed |
| High | ~250 | ~4.8 | ~0.68 | Hatchery strain, Year 1, broodiness managed, 16-hr lighting, 16 to 18% protein |
The Normal row is the most realistic starting point for planning. It assumes a healthy hatchery-strain hen in her first or second year, on standard layer feed, with natural daylight and one or two short broody pauses across the year. Plan your egg budget around this number, not the High row.
Strain and broodiness move this breed more than daylight does. A hatchery production line that rarely sits will push toward 250, while a heritage exhibition bird that goes broody two or three times a year can land closer to 180. The Speckled Sussex is a steady heritage layer, not a high-output hybrid, so treat the top of the band as a good year rather than the default.
By year, month, week, and day
| Time period | Low (~180/yr) | Normal (~220/yr) | High (~250/yr) |
|---|---|---|---|
| Per year | 180 | 220 | 250 |
| Per month (average) | ~15 | ~18 | ~21 |
| Per week (average) | ~3.5 | ~4.2 | ~4.8 |
| Per day (average) | ~0.49 | ~0.60 | ~0.68 |
| Dozens per year | ~15 | ~18 | ~21 |
A hen lays one egg every 24 to 26 hours at full production, and she skips a day here and there, so the daily average never reaches a clean 1.0. The weekly average folds in molt weeks, winter slowdowns, and the occasional broody pause, which is why even a strong layer averages under five eggs a week across a full year.
The formula
Scale to any flock size:
Weekly eggs = Number of hens × 5.5 (Speckled Sussex peak eggs/week) × Age Factor × Season Factor
Use 5.5 as the peak weekly baseline, since a healthy Speckled Sussex lays 5 to 6 eggs a week at her best, then apply the factors below to adjust for age and season.
| 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 × 5.5 × 0.84 (Year 2) × 0.75 (winter, no light) = ~21 eggs per week.
Use the egg production calculator to model your specific flock by age and season instead of running the math by hand.
How production drops year over year
| Year | Per hen / year | Per hen / week | 6-bird flock / year | 6-bird flock / week |
|---|---|---|---|---|
| Year 1 (peak) | ~220 | ~4.2 | ~1,320 | ~25 |
| Year 2 | ~185 | ~3.6 | ~1,110 | ~21 |
| Year 3 | ~145 | ~2.8 | ~870 | ~17 |
| Year 4 | ~110 | ~2.1 | ~660 | ~13 |
| Year 5 | ~84 | ~1.6 | ~500 | ~10 |
Production slides down gradually rather than stopping at a set age. The Speckled Sussex holds its laying longer than most hybrids, so a well-kept hen often beats these figures slightly in years three and four before tapering. To keep your flock average high, add two or three young pullets every other year so the group always has birds in their peak window.
Month by month (first-year hen)
| Month | Natural light only | With 16-hr coop lighting | Notes |
|---|---|---|---|
| January | 14 | 19 | Shortest days, but a hardy winter layer |
| February | 16 | 20 | Days lengthening |
| March | 21 | 22 | Spring climb begins |
| April | 23 | 23 | Near peak |
| May | 24 | 24 | Peak month |
| June | 23 | 23 | Strong |
| July | 21 | 21 | Slight dip in heat |
| August | 21 | 21 | Dense feathers dislike high heat |
| September | 18 | 20 | Daylight shortening |
| October | 14 | 19 | Molt and shorter days |
| November | 13 | 19 | Low point without light |
| December | 12 | 18 | Minimum without lighting |
The Speckled Sussex is one of the better winter layers among heritage breeds, so its cold-month dip is gentler than a Leghorn’s. Natural light still lands her near 220 for the year. If you want to flatten the winter trough, start supplemental light in early September, before the days actually shorten, so production never falls in the first place rather than trying to restart it in December.
What changes the number
The single biggest swing for this breed is broodiness, followed by strain, daylight, molt, and heat.
Broodiness
Speckled lines go broody more often than the Light Sussex, and a broody hen stops laying. A typical spell runs about three weeks once you count the roughly 21 days she would sit plus a few days to come back into lay, costing 15 to 20 eggs each time. Two or three broody spells in a season can drop a hen from 240 eggs to under 200 on their own. Collect eggs daily and lift a determined sitter off the nest early if you want the eggs rather than chicks.
Strain and breeder line
Hatchery production strains sit at the top of the band, roughly 220 to 250, while heritage and exhibition breeder birds often lay 150 to 180 because they are selected for type and color rather than output. If your hens came from a show breeder, plan for the lower end and treat a 220-egg year as a win.
Daylight and coop lighting
Hens need about 14 to 16 hours of light a day to lay at full rate. The Speckled Sussex tolerates short days better than many breeds, but production still eases in midwinter. If you choose to add light, 16 hours total (natural plus artificial) from early September keeps laying steady. Keep any lighting decision optional and gentle, since a yearly rest does the hen no harm.
Annual molt
The first hard molt usually hits around 16 to 18 months and lasts 8 to 12 weeks, during which laying pauses while the hen regrows feathers. Bump feed to 18 to 20% protein through the molt to speed feather regrowth and shorten the gap. This pause is normal and not a cause for concern.
Heat stress
The dense, soft feathering that makes this breed cold-hardy works against it in heat, and laying slows once coop temperatures push past about 85 to 90°F. Provide shade, cool water, and airflow through summer. For an unexplained sharp drop in laying, lethargy, illness, parasites, or injury, consult a licensed poultry veterinarian or your local extension service.
How Speckled Sussex compare
First-year production under normal backyard conditions.
| Breed | Annual eggs | Egg color | Type | Vs Speckled Sussex |
|---|---|---|---|---|
| Speckled Sussex | 180 to 250 | Light brown | Dual-purpose | Baseline |
| ISA Brown | 300 to 320 | Brown | Hybrid | Higher |
| Rhode Island Red | 250 to 300 | Brown | Heritage | Higher |
| Plymouth Rock | 200 to 280 | Brown | Heritage | Similar |
| Buff Orpington | 180 to 220 | Light brown | Heritage | Lower |
The Speckled Sussex is the right pick if you want a calm, cold-hardy, dual-purpose bird that lays dependably through winter and doubles as a friendly, kid-safe flock member. It is one of the easiest heritage breeds to keep, and the mahogany-and-white speckled plumage is a genuine draw. It dates to the Sussex region of England, gained its breed standard in 1914, and was a leading English table bird before commercial Cornish crosses took over, which is why it carries more body than a pure layer.
Skip it if raw egg count is your only goal. A hybrid like the ISA Brown will out-lay it by 80 to 100 eggs a year and will not interrupt that output with broody spells. The Speckled Sussex trades a little volume for hardiness, longevity, and temperament.

Frequently asked questions
How many eggs does a Speckled Sussex lay per year?
A Speckled Sussex hen lays 180 to 250 eggs per year, with about 220 being a realistic planning figure for a healthy first- or second-year hen. Hatchery strains reach the top of that range, while heritage breeder lines and frequent broody spells pull it toward the bottom.
How many eggs does a Speckled Sussex lay per week?
At peak, a healthy Speckled Sussex lays 5 to 6 eggs per week. Averaged across a full year, including molt, winter, and broody pauses, that works out closer to 4 eggs a week.
When do Speckled Sussex start laying?
Most Speckled Sussex hens start laying around 20 weeks of age, with a normal window of 16 to 22 weeks. They tend to mature slightly later than the Light Sussex, so do not worry if a pullet takes until 22 weeks to lay her first egg.
Do Speckled Sussex lay in winter?
Yes, the Speckled Sussex is one of the steadier winter layers among heritage breeds thanks to its dense feathering and hardiness. Output still drops in the shortest months, but many keepers report eggs right through winter, especially with a 16-hour light schedule started in early September.
How many eggs will 6 Speckled Sussex hens lay per year?
Six first-year Speckled Sussex hens lay roughly 1,300 eggs a year, or about 25 a week at peak, dropping toward 1,100 in their second year. Use the egg production calculator to adjust that estimate for your hens’ ages, your winter lighting, and how often your birds go broody.
Why did my Speckled Sussex stop laying?
The most common reasons are broodiness, annual molt, shorter winter daylight, or simple age, all of which are normal. If the stop is sudden and paired with lethargy, weight loss, or other signs of illness or injury, consult a licensed poultry veterinarian or your local extension service rather than guessing.
What color eggs do Speckled Sussex lay?
Speckled Sussex hens lay light brown to lightly tinted eggs, medium to large in size, despite the speckled name applying to their feathers and not their shells. Shell shade varies a little from hen to hen but stays in the light-brown range.
