Chicken Molting: Why Your Hens Lose Feathers and Stop Laying

One autumn you’ll walk out to find feathers everywhere and a coop full of scruffy-looking hens that have suddenly stopped laying. Before you panic: this is almost always a molt — a normal, healthy, annual event.

What’s happening and why

As daylight shortens in fall, mature hens shed their worn feathers and grow a fresh set to carry them through winter. Because feathers are about 85% protein, building a whole new coat is demanding — so the body reallocates energy away from laying. A pause or steep drop in eggs during a molt is expected and temporary.

Molting usually begins when a hen is 16–18 months old, then recurs roughly once a year. It typically follows a pattern from head and neck down the body to the tail.

How to support a molting flock

  • Raise the protein. Switching to a higher-protein feed (or a feather-fixer/grower-type feed) during the molt supports feather regrowth. Ease back to layer feed once they’re done.
  • Go easy on handling. New “pin feathers” have a blood supply and are tender — molting birds often dislike being picked up. Give them space.
  • Keep stress low. Avoid big changes (new flock members, moves) mid-molt.
  • Maintain clean water and a dry, draft-free coop — see winterizing, since molts and cold weather often overlap.

Normal molt or a problem?

A molt and a health issue can look similar, so check the pattern:

  • Normal molt: feather loss is fairly symmetrical, new pin feathers are visibly coming in, and the bird is otherwise bright, active, and eating.
  • Possible problem: bald patches with no regrowth, redness or scabs, lethargy, or feather loss only around the vent can point to mites/lice, feather-picking, or illness rather than a molt. When in doubt, inspect closely (especially at night for mites) and consult an avian vet.

Most of the time, the answer is simple: feed them well, leave them be, and the eggs return with a beautiful new set of feathers.

Common questions

What is molting in chickens?
Molting is the natural, annual process of shedding old feathers and growing new ones. It usually happens in autumn as daylight shortens, typically starting when a bird is around 16–18 months old and then once a year after that.
Do chickens stop laying when molting?
Most do, yes. Growing feathers is protein-intensive, so hens divert energy from egg production and usually pause or sharply reduce laying until the molt finishes. It's normal, not a problem.
How long does a molt last?
Anywhere from about 8 to 16 weeks. 'Fast' molters drop feathers dramatically and recover quickly; 'slow' molters look scruffy for longer. Older birds often take longer.
