Molting in Backyard Hens: What It Is and How to Feed Through It

One morning you walk into the run and think a predator has been through. Feathers are everywhere, a few hens look half-naked and the nest boxes are empty. Before you panic, check the calendar. If it is autumn and your hens are a year or more old, they are probably molting, the annual feather replacement that every healthy chicken goes through.

This guide explains what molting is, how it looks in Speckled Sussex and other hens, how long it lasts and what you can do to help. Hens vary, and feed advice depends on your flock and region, so check with local extension or a poultry vet.

What Molting Is

Molting is the process of shedding old, worn feathers and growing new ones. It usually happens once a year, most often in late summer to fall, when daylight shortens. Hens stop or reduce laying so their bodies can put energy and protein into feather growth. Pullets typically have a partial molt in their first year, and a full, more dramatic molt the following year.

What It Looks Like

• Feathers dropping in large numbers, first around the neck, then body, with tail feathers often last.
• Pin feathers, which are the new feathers growing in, look like small spikes or quills.
• Bare patches that look alarming but are normal.
• Less activity, with some hens appearing grumpy or reluctant to be handled because new feathers are sensitive.
• Egg production stopping or slowing sharply.

How Long It Lasts

A molt may take anywhere from several weeks to a few months, depending on the hen, her age and her health. Some hens molt quickly, losing and regrowing feathers in a matter of weeks, while others take longer. Fast molters often return to laying sooner. Extension poultry resources, such as Penn State Extension and eXtension, describe molt timing in more detail.

Feed for Feathers

Feathers are mostly protein, so hens in molt need good protein in their diet. Many keepers switch from layer feed, which is about 16 percent protein, to a higher-protein feed, such as a grower or flock raiser feed with around 18 to 20 percent protein, during the molt, and offer oyster shell on the side for hens that are still laying. Some also give protein-rich treats such as mealworms, black soldier fly larvae or scrambled eggs, in moderation. Check the guidance from your feed supplier or a poultry nutritionist, since feeding the wrong ration can cause problems, especially if roosters are in the flock, since extra calcium is not good for non-laying birds.

Keep Stress Low

Molting hens are more sensitive and can get chilled. Avoid handling them more than necessary, since new pin feathers can be painful. Provide a dry, draft-free coop, plenty of clean water and shelter from cold rain. Reduce stress from changes in flock makeup, and keep predators out. Stress can slow regrowth.

Molt, Mites or Illness?

Feather loss does not always mean molt. Signs that point to something else include:

• Feather loss in the wrong season, such as spring, or sudden, patchy loss on a young hen.
• Itchy, scabby or irritated skin, which may signal mites or lice.
• Feather pecking by other hens, which causes loss on backs and vents.
• Lethargy, weight loss, diarrhea or other signs of illness.
• Rooster mating damage on the back and neck of hens.

Check hens for external parasites, look at the skin and watch flock behavior. If a hen seems sick, consult a vet. The Merck Veterinary Manual has general information on poultry health.

Should You Force a Molt?

Commercial egg farms sometimes use forced molting methods, such as feed withdrawal, to restart production. This is controversial and regulated or restricted in some places, and it is not recommended for backyard flocks. Let hens molt naturally, and give them good feed and care.

Lights and Molting

Adding artificial light to keep hens laying through autumn can delay molting, and shortening light can trigger it. Many keepers prefer to let hens follow their natural cycle, giving them time to rest and rebuild. If you use supplemental light, keep the schedule consistent, and see our guide on winter laying for details.

After the Molt

When the new feathers come in, hens often look glossy and beautiful, especially the Speckled Sussex, whose new plumage shows deeper mahogany with fresh white tips. Egg laying resumes, though some older hens lay less than before. Return to your regular layer feed once most hens have finished regrowing feathers and begun laying again.

Common Molting Mistakes

• Panicking. Feather loss in the fall is normal.
• Underfeeding protein. Feathers need it.
• Overhandling. Pin feathers are tender.
• Missing a real problem. Check for mites and illness.
• Chilling hens. Keep them dry and out of wind.
