Why hens stop laying in fall

Hens often stop or slow laying in fall for two overlapping reasons: shorter daylight and molt. Molt spends protein on feathers. Day length spends less time lighting the ovary. A bag of powder will not override winter photoperiod.

Abundant Permaculture puts it plainly: late fall and winter cut hours of daylight that stimulate the ovary (Abundant Permaculture). Purina’s Patrick Biggs, Ph.D., calls molt an annual vacation from laying while hens grow winter feathers, usually as sunlight drops (Purina). Meyer Hatchery notes not every hen stops, but production often drops as days shorten (Meyer Hatchery).

What to put in front of them

Start with a complete feed. Supplements work best on top of a solid base, not in place of one. Whether your hens are molting or their eggs are slowing for the season, a balanced, complete feed should make up the bulk of their diet. Treats and supplements should stay at roughly 10% or less of what they eat, or you'll dilute the nutrition they need most.

If they're molting, boost the protein. Feathers are about 85% protein, so growing a whole new set is a big nutritional job. That's why Biggs recommends more protein in the feed during molt. Many keepers move to a higher-protein feed (often 16–20%) until new feathers are in. Once eggs return, Purina suggests easing back to layer feed over 7–10 days rather than switching all at once, which is easier on their digestion and keeps their intake steady.

Keep the extras simple and targeted:

• Black Soldier Fly Larvae (BSFL): A natural, protein-rich treat that's also a good source of calcium. It's an easy way to add protein during molt without overhauling their feed, and hens love it. Scatter a handful in the run to encourage foraging, which also helps keep bored, stressed molters busy.
• Brewer's Yeast with Garlic: A source of B vitamins and protein, plus garlic for a little extra appeal. B vitamins support feather regrowth and overall vitality, and molting hens are often run-down, so this is a helpful sprinkle on feed.
• Flock Flax (later in the season): Flax is a source of omega-3 fatty acids. Add it once feathers are growing back and you're heading into winter, when you want to support egg quality and production through the shorter days.

A Few Other Tips for Molting and Slowing Hens

• Handle them gently. New pin feathers are tender and can be sore, so keep handling to a minimum.
• Offer oyster shell free-choice. Even if eggs have paused, laying hens should still have calcium available. Layers will take what they need.
• Provide fresh, clean water and consider adding electrolytes on hot days.
• Don't panic about the drop in eggs. Molt typically hits in the fall and can last 8–16 weeks. Production usually returns on its own once feathers are back.
• Watch for other causes of slowing. If a hen isn't molting but eggs have stopped, consider shorter daylight, stress, illness, parasites, or age. Check for mites and lice, and see a vet if she seems unwell.

Will they start again?

Usually after molt and as days lengthen, if they are still in a laying life stage. Older hens lay fewer eggs even in spring.
