Why Would Hens Stop Laying Eggs?

A chicken's egg productivity depends on a number of internal and external factors, according to the Oregon State University Extension. The egg yield varies by breed of chicken, but good nutrition and a healthy environment go a long way toward keeping hens healthy and productive.

  1. Day Length

    • Decreasing day length causes chickens to molt, or lose their feathers and grow new ones. Hens stop laying eggs while they molt.

    Broodiness

    • Broodiness is the tendency chickens have to sit on eggs to hatch them, regardless of whether they are fertilized or not. While hens are doing this, they stop laying eggs.

    Disease

    • When a hen stops laying eggs, it may be an early indicator of disease in the flock. In this case, the stoppage will often be accompanied by lethargy, lameness, coughing, dull appearance and death. If several birds show these signs, contact a veterinarian.

    Age

    • When hens are two to three years old, their egg production naturally decreases.

    Stress

    • Various stress factors--such as moving, overheating, fright, handling and lack of food and water--can cause hens to stop laying eggs.
