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.
