What to expect from Hamburg layers
| First egg | 18–22 weeks (4.1–5.1 months) |
| Egg color | white |
| Eggs per year | ≈ 200–220 in the first laying year |
| Size class | standard |
An old European breed once called the "Dutch Everyday Layer" — small white eggs, nearly every day, from a bird that would rather forage than sit in a run.
Why your Hamburg might lay earlier or later
The 18–22 week window is typical, not guaranteed — individual hens vary, and hatchery strains of a breed often lay earlier than show-line birds bred for looks over production. The biggest wildcard is daylight: laying is triggered partly by day length, so a pullet reaching laying age in late fall commonly waits for the lengthening days of late winter, no matter what the calendar math says. Spring-hatched chicks usually run on schedule.
You'll know eggs are close when the comb and wattles flush red and the pullet starts squatting when you reach toward her — first eggs usually arrive within a week or two of the squat. Switch to layer feed around week 18 (or at the first egg), keep oyster shell available, and expect the first few eggs to be small or odd-shaped while her system calibrates. All normal, all edible.
