Molting of laying hens

Each year chickens molt, or lose the older feathers, and grow new ones. Most hens stop producing eggs until after the molt is completed. The rate of lay for some hens may not be affected, but their molting time is longer. Hens referred to as "late molters" will lay for 12 to 14 months before molting, while others, referred to as "early molters," may begin to molt after only a few months in production. Late molters are generally the better laying hens and will have a more ragged and tattered covering of feathers. The early molters are generally poorer layers and have a smoother, better-groomed appearance.

Early molters drop only a few feathers at a time and may take as long as 4 to 6 months to complete the molt. Early molters are usually poor producers in a flock. Late molting hens will produce longer before molting and will shed the feathers quicker (2 to 3 months). The advantage of late molters is that the loss of feathers and their replacement takes place at the same time. This enables the hen to return to full production sooner.

The order in which birds lose their feathers is fairly definite. The feathers are lost from the head first, followed in order by those on the neck, breast, body, wings, and tail. A definite order of molting is also seen within each molting section, such as the loss of primary flight feathers before secondary flight feathers on the wings.

The primary wing feathers determine whether a hen is an early or late molter. These large, stiff flight feathers are observed on the outer part of each wing when the wing is spread. Usually 10 primary feathers on each wing are separated from the smaller secondary feathers by a short axial feather.

Molting birds lose the primary feathers in regular order, beginning with the feather nearest the axial feather and progressing to the outer wing-tip feathers. Late molting hens will lose primary feathers in groups of two or more feathers, whereas early molters lose feathers individually. Replacement feathers begin to grow shortly after the old feathers are shed. Late molting birds can be distinguished by groups of replacement feathers showing similar stages of growth.

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.
