Quick answer: chicken molting is the yearly shedding and regrowth of feathers, usually in fall as the days get shorter. Most hens have their first adult molt at around 18 months, a molt lasts about 8 to 12 weeks (some heritage breeds take up to 16), and hens stop or nearly stop laying until the new feathers are in.
The first fall I kept chickens, I walked out to the coop and it looked like a pillow had exploded. Feathers everywhere, one of my hens half bald, and no eggs in the nest boxes. I honestly thought something had attacked them.
It was just molting. Since then I’ve seen my flock through a lot of molts, and this is everything I wish someone had told me that first year: what molting is, how long it lasts, what it looks like, how to feed a molting chicken, and how to tell a normal molt from mites or feather pecking.
What is chicken molting?
Molting is how a chicken swaps out old, worn feathers for a fresh set. Feathers don’t last forever. After a year of dust baths, rain, sun and roosting, they get broken and dull, and they don’t insulate as well.
Shorter days are the main trigger. When daylight drops in late summer and fall, a hen’s body reads it as a signal that winter is coming. She drops the old feathers and grows new ones that trap a warm layer of air between the feathers and her skin, right before she needs it most.
Growing a whole new coat takes a lot of protein and energy, so a molting hen puts her resources into feathers instead of eggs. That’s why molting and an empty nest box go hand in hand.
When do chickens molt?
Adult chickens usually molt once a year, in late summer or fall. In my flock it starts around September and the last stragglers are finished by December.
A hen’s first adult molt normally happens at around 18 months old, so a pullet hatched in spring usually skips a molt her first fall and molts the following one. When she started laying can shift that timing a little.
Chicks molt too. According to Murray McMurray Hatchery, the first juvenile molt starts when chicks are only 6 to 8 days old, as their fluffy down gives way to real feathers. They go through partial molts again at about 7 to 9 weeks, 12 to 16 weeks, and a final one at 20 to 22 weeks before they’re grown. Young cockerels get an extra molt at 8 to 12 weeks when their showy saddle and tail feathers come in.
Molting can also happen out of season. Stress, a broody spell, a move, a predator scare, a heat wave, or running out of food or water for a day can all push a hen into a partial molt in spring or summer.
How long does molting last?
Most backyard hens take about 8 to 12 weeks from the first dropped feather to a full new coat. Some take longer. The University of Kentucky Cooperative Extension notes that commercial laying strains can molt in 4 to 6 weeks, while heritage breeds can take three to four months.
Each bird runs on her own clock, so the whole flock won’t molt at once. In a mixed flock, the season can stretch to three months or more from the first hen to the last. My fast, high-production layers are always done well before my fluffy Orpingtons.
Hard molt vs soft molt
Not every molt looks dramatic. Backyard keepers talk about two kinds.
Soft molt: the hen loses feathers slowly over several weeks. You’ll notice more feathers on the coop floor and maybe a slightly scruffy look, but she never looks bald. Some hens keep laying, just less often.
Hard molt: the hen drops a lot of feathers fast. She can look almost naked around the neck, back or vent, and she’ll stop laying completely. It looks alarming, but it’s normal, and hard molters often regrow their feathers faster.
What does a molting chicken look like?
Feathers come out in a predictable order. The University of Kentucky Extension lists it as head, neck, chest, body, wings, then tail. So the first thing I usually notice is a scruffy neck and little feathers stuck in the shavings, and the tail is the last thing to fill back in.
Other signs of molting in chickens:
- Piles of feathers in the coop and run, especially small body feathers
- Bare or thin patches on the neck, back and around the vent
- Pin feathers: spiky, quill-like shafts poking out of the skin
- A paler, smaller comb and wattles
- Fewer eggs, or none at all
- A hen who is a little quieter, grumpier or less keen to be handled
Is molting painful for chickens?
Molting itself isn’t an injury, but it can be uncomfortable. New pin feathers have a blood supply running through the shaft while they grow, which makes them tender. You can read more about how feathers grow and regrow from the Cornell Lab of Ornithology.
My hens tell me loud and clear that they don’t want to be held while they molt. I skip the cuddles and only pick them up when I have to, supporting the body from underneath and keeping my hands off the pin feathers. If a pin feather gets broken and bleeds, separate the hen until it stops, because bright red spots attract pecking from the rest of the flock.
Do chickens stop laying eggs when they molt?
Yes. A hen in a hard molt stops laying entirely, and a hen in a soft molt usually slows way down. Her body is putting its protein into feathers, and it can’t do both at full speed.
Expect the egg break to last roughly as long as the molt, about 8 to 12 weeks for most hens. Laying usually picks back up once the new feathers are mostly in. Since molt overlaps with short winter days, some hens don’t really get going again until late winter or early spring. If your hens have stopped and they aren’t molting, my post on reasons why hens stop laying eggs covers the other usual suspects.
What to feed molting chickens
Feathers are mostly protein (roughly 85 to 90%, almost all of it keratin), so protein is the single biggest thing you can give a molting flock. Regular layer feed runs about 16% protein. During molt, I switch my hens to an 18 to 20% protein feed.
- Switch to an 18 to 20% feed. An all-flock, grower or feather-fixer feed works well. These have less calcium than layer feed, so put out a separate dish of oyster shell.
- Cut back on scraps and scratch. They fill hens up without much protein and dilute the feed.
- Add protein treats in small amounts. Dried mealworms or black soldier fly larvae, scrambled eggs, black oil sunflower seeds or a little plain canned tuna. I have a full list of high protein foods for molting chickens.
- Keep fresh water in front of them. A splash of poultry vitamins and electrolytes in the waterer can help during the worst of it.
- Let them forage if you can. If your hens are usually in a small run, some supervised time to free range gives them bugs and grubs.
Once most of the new feathers are in and the eggs start coming back, switch back to layer feed. Don’t leave hens on high-protein grower feed indefinitely, and don’t use broiler or meat-bird feed for months on end. Too much protein for too long is hard on their kidneys.
How to help your chickens through a molt
Beyond feed, the goal is to keep stress low so the molt goes quickly.
- Don’t add new birds. Introductions shuffle the pecking order and lead to pecking at tender pin feathers. Save introductions for after molt.
- Keep handling to a minimum. No baths, no shows, no moving coops.
- Give them space. Crowding leads to boredom and pecking, and half-bald hens are an easy target.
- Keep the coop dry and draft-free. Good ventilation is still important, but block drafts at roost height for hens with bare patches.
- Keep up parasite checks. Molt is a good time to look under feathers, since there are fewer of them.
Molting vs mites vs feather pecking
Not all feather loss is molting. Here’s how I tell the difference. For the full rundown, see my post on reasons chickens lose their feathers.
| Sign | Molting | Mites or lice | Feather pecking |
|---|---|---|---|
| Time of year | Late summer to fall | Any time, often worse in warm months | Any time |
| Where feathers go | Head and neck first, then body, wings, tail | Vent, under wings, around the tail | Back, tail base, vent or head (where others can reach) |
| Skin | Clean, with new pin feathers | Scabby, red or crusty; tiny bugs or egg clusters at feather bases | Broken feather stubs, scabs or wounds |
| Who is affected | One hen at a time, spread out over weeks | Often several birds at once | Usually the lowest birds in the pecking order |
| Behavior | A bit quiet, otherwise normal | Restless, scratching, pale comb, fewer eggs | Bullied hen hides; other hens chase and pull feathers |
| What to do | Higher protein feed, low stress, wait it out | Treat birds and coop; see parasite control | More space, distractions, separate the victim; see stopping pecking |
One quick check: part the feathers around the vent at night with a flashlight. If you see crawling specks or grayish egg clusters stuck to the feather shafts, it’s not just molting.
What not to do during molt
- Don’t pull out pin feathers or loose feathers to speed things up.
- Don’t put sweaters on chickens. They interfere with feather growth and preening.
- Don’t add a coop heater because a hen looks bare. Chickens handle cold far better than we think, and heaters are a fire risk.
- Don’t add artificial light to force eggs during molt. Let her finish first.
- Don’t fill them up on scratch grains and kitchen scraps.
- Don’t assume every bald hen is molting. Check for mites and bullying. If it is mites, here is how to treat chicken mites.
Do roosters molt?
Yes. Roosters molt every year just like hens, usually in fall, and it takes about the same 8 weeks or more. My rooster looks pretty sorry for himself without his long tail feathers, but they always come back. Roosters don’t lay, so the only real change you’ll notice is how they look.
Can molting kill a chicken?
A normal molt doesn’t kill a healthy chicken. Problems come from things that ride along with it: a hen that was already sick, poor nutrition, heavy mite infestations that make her anemic, or flockmates pecking at her bare skin.
A molting hen should still eat, drink, dust bathe and act mostly like herself. If she’s hunched, not eating, has diarrhea or seems lethargic for more than a day or two, it’s not the molt. Go through these signs your chickens are sick and call a vet who sees poultry.
Do molting chickens get cold?
Usually not. Molting starts in fall precisely so the new feathers are in before the coldest weather. A dry, draft-free coop is all most hens need. If a hen is caught late and still bare in a hard freeze, make sure she has a sheltered roost and her flockmates to huddle with. My post on whether chickens can survive winter covers cold-weather care.
Will all my chickens molt at the same time?
No. Each chicken molts on her own schedule depending on her age, breed and when she started laying. Older hens often molt earlier and take longer. Expect a few weeks of staggered feather drops across the flock, and fewer eggs overall until everyone is done.
My take
Molting looks scary the first time, but it’s one of the most normal things a chicken does. Bump up the protein, keep things calm, check for mites, and give it time. In a couple of months your hens will be glossier than ever and back in the nest boxes.
Keep your hens safe, and happy egg collecting!

Frequently Asked Questions
What is chicken molting?
Chicken molting is the yearly process where a chicken sheds its old, worn feathers and grows a new set. It is triggered mainly by shorter days in late summer and fall, and it gives the bird fresh, insulating feathers before winter. Hens usually stop or slow laying while they molt.
How long does molting last in chickens?
Most backyard chickens take about 8 to 12 weeks to finish molting, from the first lost feathers to full regrowth. Commercial laying strains can be done in 4 to 6 weeks, while heritage breeds can take three to four months. Tail feathers are usually the last to grow back.
At what age do chickens start molting?
Chickens have their first adult molt at about 18 months old, usually in the fall. After that they molt once a year. Chicks also go through partial juvenile molts at about 1 week, 7 to 9 weeks, 12 to 16 weeks and 20 to 22 weeks as down is replaced by adult feathers.
Do chickens stop laying eggs when they molt?
Yes. A hen in a hard molt stops laying completely, and a hen in a soft molt lays much less. Her body puts its protein into new feathers instead of eggs. Laying usually resumes once most new feathers are in, roughly 8 to 12 weeks after the molt starts.
What should you feed molting chickens?
Switch molting chickens to an 18 to 20% protein feed, such as an all-flock or feather-fixer feed, and offer oyster shell on the side for calcium. Cut back on scraps and scratch, and add small amounts of protein treats like mealworms, scrambled eggs or black oil sunflower seeds. Switch back to layer feed when laying resumes.
What is the difference between a hard molt and a soft molt?
In a soft molt a chicken loses feathers gradually over weeks and never looks bald, and she may keep laying at a slower rate. In a hard molt she drops many feathers quickly, can look almost naked in places and stops laying completely. Both are normal.
Is molting painful for chickens?
Molting can be uncomfortable because new pin feathers have a blood supply and are tender to the touch. Avoid handling molting hens unless necessary, support them from underneath and keep your hands off the pin feathers. A normal molt does not harm a healthy chicken.
How can I tell molting from mites?
Molting starts at the head and neck, happens mostly in fall and leaves clean skin with new pin feathers. Mites and lice usually cause feather loss around the vent and under the wings, with scabby or red skin and tiny bugs or egg clusters at the feather bases. Check under the feathers with a flashlight at night.
