Why do hens stop laying eggs?

If laying hens are receiving proper management, the most common reason for reduction of lay is a reduction of light. The reproductive state of all birds is strongly regulated by the amount of light that they receive each day. If hens are to maintain a constant state of egg production, they must be subjected to at least 16 hours of light every day. This light can be provided from sunlight, artificial light sources, or a combination.

When the day length is increasing between December 21 and June 21, the birds are stimulated into an increased reproductive state, but between June 21 and December 21, the reverse occurs and the birds cease to produce eggs. These effects produce the natural breeding seasons for birds in a natural environment. The recommended rule of lighting for pullets and hens is: "Never increase light on growing birds, but never decrease light on mature laying hens." A violation of this rule results in undesirable hens that do not lay eggs.

A good lighting program for hens requires that light be provided at:

  1. The proper length of time every day.
  2. A minimum intensity.
  3. The proper color.

The recommended day length is 16-18 hours daily. The minimum light intensity is 1 foot-candle or sufficient light to clearly see the level of feed while standing over the feeder. The stimulatory color of light is a yellow or orange that approximates the spectrum of sunlight. Artificial light fixtures that provide excellent light for laying hens are incandescent bulbs, warm-white fluorescent tubes, and many of the halogen lights that produce a yellowish colored light.

STARKVILLE, Miss. -- The poultry industry is the giant in the state’s agricultural economy, as its estimated 2017 production value of $2.8 billion nearly doubles the value of forestry.

Early figures from the Mississippi State University Extension Service show the industry grew at an estimated 13.4 percent from the 2016 value. Brian Williams, Extension agricultural economist, said higher broiler prices are responsible for the value increase.

In three days, Teresa Dyess shifted her business focus from produce to poultry.

The change began two years ago with an offhand remark from her husband, Joe Dyess.

 “He told a broiler grower in Wayne County we wouldn’t mind building pullet houses because we wanted to diversify our farm,” she said. “We didn’t think any more about it, and then the next day a poultry processor called and offered us a contract. A banker came the next day, and everything fell into place.”

Lanette Crocker, coordinator for the MSU Extension Service in Wayne County, said Teresa Dyess’ adaptability has helped her maintain success through the farm’s transition.

STARKVILLE, Miss. -- All Mississippians who raise any species of poultry are being urged to follow strict biosecurity practices and review new requirements regarding sales and exhibitions.

Tom Tabler, poultry specialist with the Mississippi State University Extension Service, said that while avian influenza is not a threat to human health or food safety, an outbreak would endanger backyard flocks and the state’s nearly $3 billion commercial poultry industry.
