One morning the coop looks like a pillow exploded. Your best layer is half bald, the eggs have stopped, and the flock looks miserable. That is a molt, and it is normal. The feeding question it raises has a simple answer: feathers are 80 to 85% protein, so during a molt your hens need more protein than layer feed provides.
Standard layer feed runs about 16% protein, which is built for laying, not for growing a whole new set of feathers. During molt, switch to something in the 18 to 20% range. That single change does more than any supplement, tonic, or treat. Everything else in this article is fine-tuning around it.
The molt feeding plan
Switch the base feed. Move the flock to a grower or all-flock ration at 18 to 20% protein for the duration of the molt. These feeds are easy to find at any feed store and cost roughly the same as layer feed. When the molt finishes and laying resumes, switch back to layer feed.
Cut the scratch. Scratch grains and straight corn are low in protein, and every beakful of scratch displaces beakfuls of the protein-rich feed your hens actually need. During molt, keep scratch and other low-protein treats at 10% of the diet or less, or skip them entirely. This is the hardest part for most keepers, because tossing scratch is fun. The hens will forgive you.
Add small protein treats. Dried mealworms, black soldier fly larvae, black oil sunflower seeds, and a few scrambled eggs are all good options. Treats stay treats: a small handful per bird a few times a week, not a second ration. The base feed does the heavy lifting.
Keep oyster shell out. Hens that have finished molting, or have not started yet, still need calcium. Offer oyster shell free-choice in a separate dish so each bird takes what she needs. Do not mix it into the feed. For the protein side of the same equation, how much protein laying hens need covers the baseline numbers.
The 10-hen example
Take a flock of 10 hens eating roughly a quarter pound of feed each per day, about 2.5 pounds a day for the flock. On 16% layer feed, that is roughly 0.4 pounds of protein a day. On 20% grower feed, it is 0.5 pounds a day, a 25% increase, without feeding a single extra ounce.
Over an 8 to 12 week molt, the flock eats roughly 140 to 210 pounds of feed, three to four 50-pound bags. The price difference between layer and grower feed is usually small, so the whole molt feeding upgrade costs a few dollars per bag. Compared with the price of a bag of dried mealworms, the feed switch is the bargain of the season.
Eggs will still stop. That is not a feeding failure. A hen cannot grow feathers and lay eggs at full speed at the same time, and the molt wins. Expect laying to return as the new feathers finish coming in. Hens that molt hard, dropping most feathers at once, often come back into lay sooner than hens that molt slowly, even though they look worse for a few weeks.
The part that is not about feed
New pin feathers hurt. Each one carries an active blood supply while it grows, and bumping one is painful for the bird. So during molt, handle your hens as little as possible. Move slowly around the flock. Skip the saddles and jackets, which rub on bare skin and irritate growing feathers. And keep stress low: no new birds, no coop construction, no big changes while the flock is half naked and grumpy.
Watch for feather picking, too. The blood in pin feathers can attract attention from flockmates, and a flock short on protein sometimes turns on feathers as a source. If you see picking, check that the feed switch actually happened, scatter some treats for distraction, and separate any bird that is being targeted. The behavior usually fades once the feathers finish growing.
One more thing worth saying plainly: there is no quick fix for molt. No supplement makes feathers grow overnight. The hens are doing hard biological work on a schedule you cannot rush. Feed them well, leave them alone, and wait. The feathers come back, the eggs come back, and the coop stops looking like a pillow factory.
Questions people ask about feeding molting chickens
What should I feed chickens during molt?
Switch from standard 16% layer feed to a feed with 18 to 20% protein, such as a grower or all-flock ration. Add small amounts of protein-rich treats like mealworms or sunflower seeds, and cut scratch grains back to 10% of the diet or less.
How long does a chicken molt last?
Most molts run 8 to 12 weeks, though some hens finish faster and poor layers can take much longer. A hard molt, where the hen drops most feathers at once, often finishes sooner than a slow, gradual soft molt.
Do molting chickens stop laying eggs?
Usually yes. A hen's body cannot support full feather regrowth and egg production at the same time, so laying drops sharply or stops entirely until the molt finishes. Eggs return once the new feathers are in.
Should I still offer oyster shell during molt?
Yes. Keep oyster shell available free-choice. Hens that have finished molting or have not started yet still need calcium, and a hen coming back into lay needs it ready. Do not mix it into the feed; let each bird take what she needs.
Can I handle molting chickens?
As little as possible. New pin feathers carry an active blood supply and are painful when pressed or bumped. Handle only when necessary, move slowly around the flock, and skip saddles or jackets until the feathers are fully grown.
