when do hens start laying eggs

Most hens start laying their first eggs at around 18–22 weeks of age (about 4½–5½ months), depending on breed, daylight, and overall care.

Quick Scoop

  • Typical backyard hens begin laying at 18–22 weeks under good conditions.
  • Some early-maturing breeds (like lightweight egg layers) may start as soon as about 16 weeks, while heavier heritage breeds can take 24–28 weeks or more.
  • Hens need enough daylight (about 14–16 hours), proper nutrition, and low stress to kickstart and maintain laying.

Mini Breakdown: What Affects “Start Time”?

  • Breed: Lighter breeds (such as high-production white egg layers) tend to mature and lay earlier; larger dual‑purpose or heritage breeds often mature more slowly.
  • Age & maturity: The “normal” window for most pullets (young hens) is roughly 5–6 months old.
  • Daylight: If your pullets reach laying age in fall or winter, they may wait until spring when natural daylight reaches roughly 12–14+ hours.
  • Nutrition & housing: A balanced layer feed around 16–18 weeks, clean housing, and low stress all support their bodies to start producing eggs.

Little Story-Style Example

Imagine you bought a batch of spring chicks in late March.
By August, they’re about 20–22 weeks old, fully feathered, combs brightening, and suddenly you find a small “practice” egg in the nesting box—that’s exactly the age range most people see their first eggs. If those same chicks hit 18–20 weeks in November instead, they might keep you waiting until longer spring days arrive, even though they’re technically old enough to lay.

Simple Signs Your Hen Is Close

Many keepers notice these hints just before the first egg:

  1. Redder, fuller comb and wattles.
  2. Squatting when you reach to touch her back.
  3. Exploring and sitting in nesting boxes.
  4. Louder or more “chatty” behavior.

Quick TL;DR

Most hens start laying eggs at about 18–22 weeks old, earlier for some light breeds and later for big heritage types, and they need plenty of daylight, good feed, and low stress to get going.
