Signs a pullet is about to lay

Look for a comb and wattles that turn from pink to bright red, a hen that squats when you reach down to her, and new interest in the nest boxes. Putting a ceramic or wooden "dummy" egg in the nest shows young hens where to lay. Expect first eggs to be small, oddly shaped or soft-shelled for a week or two. That's normal.

Gear that helps

  • Ceramic or wooden dummy eggs
  • Layer feed and oyster shell, ready ahead of point of lay
  • Leg bands for telling hens of the same breed apart

Frequently asked questions

How long do chickens live?

Backyard hens commonly live 5–10 years. Laying slows considerably after about 3–4 years.

Why haven't my 26-week-old hens started laying?

Breed, short daylight and stress all delay laying. Dual-purpose and heavy breeds reaching maturity in fall or winter may not start until days lengthen.
