The fall
molt

Every fall somebody walks out to the coop, finds what looks like a pillow fight with no pillow, and one hen standing in the middle of it looking like she lost. That is the molt. Do chickens molt in the fall? Yes — it is when most of them do it, every year, and it is the most normal ugly thing a chicken does.

The trigger is the light, not the thermometer. A hen’s laying runs on day length: University of Minnesota Extension puts it at twelve to fourteen hours of light a day to keep her laying. When late summer slides under that, her body shuts the egg plant down and spends the break on the job it has been putting off — throwing out a year of broken, sun-bleached, rooster-worn feathers and growing a clean coat before winter. Molt is not something going wrong. It is scheduled maintenance.

Not everybody gets the memo at once. Pullets hatched this spring usually skip it and lay through their first winter; it is the older hens that go bald in October. And the ones that start early and drag it out are, generally, not your best layers — Mississippi State Extension notes the hens that lay a full year and then molt fast are usually the better birds. Your best layer may look the worst for two weeks. That is the deal.

This is the answer to “what to feed molting chickens,” and it is one bag. Ordinary layer feed runs about 16% protein. For the molt, the feed mills and most keepers we know bump it to 18–20%. The extension offices get to the same place by a slightly different road — Alabama Extension says to pull the layer feed while they are not laying, feed a non-layer ration, and put out a calcium supplement on the side. Both roads end at the same sack: an all-flock or “flock raiser” feed at 18–20% protein, with oyster shell in its own dish.

The lower calcium is the point, not a side effect. A layer ration carries 2.5 to 3.5% calcium to build eggshells, and a hen that is not making shells does not need it. The ones that are still laying will go to the oyster-shell dish on their own. If you keep a rooster or mixed ages anyway, all-flock is what you ought to be feeding year-round. If you want one bag and one dish, a molt-season layer feed in the 18% range keeps the layer calcium in and does the same job. Switch when the feathers start flying, switch back when she is feathered out and laying, and mix old and new over a week so nobody gets offended.

Now the part where people undo the bag. Scratch grain is roughly half the protein of layer feed, and every handful of it is room in the crop that the good feed does not get. The extension rule is no more treats and scratch than the flock cleans up in about twenty minutes. The treat that helps is a measured one: a small scoop of dried black soldier fly larvae or mealworms across the flock, not a coffee can. A scrambled egg from the kitchen works too. Yes, it is weird. It is also protein.

Molt is hard on a bird, and it runs the other direction too: stress can kick off a molt out of season. A heat wave, a move, a dog in the run, a day with an empty waterer, a long broody spell — any of them can drop feathers in May. A spring or summer molt usually means something happened. A fall molt usually just means it is fall.

In the flock, a scruffy molting hen often slides down the pecking order for a few weeks, and chickens are drawn to red. A bleeding pin feather will get pecked, and pecking escalates fast. If a bird is bleeding, pull her out — a dog crate or a spare pen with her own feed and water — until it scabs over, then slip her back onto the roost after dark, when nobody is in the mood to argue about it.

For everybody else, give the low hen a way to eat without running a gauntlet: a second feeder and a second waterer at the other end of the run. Bored birds pick, so give them something else to work on — a pile of leaves to scratch through, a cabbage hung on a string.

A half-naked hen in November looks cold, and that is the week the heat lamp comes out of the barn. Leave it there. We made the whole case in the coop winterizing guide: a heat lamp over dry shavings is a fire that has not picked its night yet, and what a bird needs, feathered or not, is a dry, draft-free coop with the vents open up high. A molting hen huddles with her sisters on a wide flat roost and does fine. If your winters throw real single-digit snaps, the one heater we would ever hang is in that guide. Most of the South, us included, needs nothing plugged in but the water.

Worry about how she acts, not how she looks. Ugly is normal. These are not:

Hunched up with her tail down and eyes half shut. Not eating or drinking. Sitting off by herself instead of going up on the roost. A keel you can feel like a knife edge when you run a hand under her. Raw skin, sores, or blood that is not from a single broken pin. Diarrhea, swelling, or noisy breathing. Or a molt that runs well past the four-to-six-month outside edge with no new feathers coming in. Any of those is a call to a poultry vet, not a shopping problem.
