An adult Leghorn hen eats about a quarter of a pound of feed a day — around half a cup of layer pellets — slightly less than a heavy dual-purpose breed, because she is a much smaller bird. That modest total powers an outsized output: Leghorns, the lean white birds behind most commercial egg production, are among the most prolific layers of all, and they achieve it by converting feed into eggs with very little diverted into body mass. The ration should be available through the day rather than served as one measured meal, so each hen eats to her own laying demand.
Efficiency Is the Leghorn Story
A Leghorn's light frame and restless, active temperament mean maintenance costs are low, but egg formation is not negotiable — a hen laying near-daily exports protein, energy, and calcium in every shell, and if the diet falls short she draws on her own body, then stops laying. That is why underfeeding never saves money with this breed: the margin comes out of the egg basket within days. It also explains why Leghorns rarely look plump even when perfectly fed. Judge her by keel and muscle in hand, not by comparing her silhouette to a round Orpington in the next run.
Layer Ration, Calcium on the Side
Offer a balanced layer ration as the flock's staple once hens are laying, with oyster shell in a separate container so each hen self-serves calcium in the late afternoon, when shell formation peaks. Grit belongs in its own dish too if birds eat whole grains or range. Scatter a small handful of scratch grains only as an afternoon activity, never as a substitute ration — Leghorns are enthusiastic foragers and will fill up on low-protein extras and short the diet that builds eggs. Clean water matters as much as the feed measure; a hen deprived of water for even part of a hot day may pause laying for days afterwards.
Foraging Changes the Feeder Bill, Slightly
Leghorns range farther and forage harder than most breeds, harvesting insects, seeds, and greens with real effect on the feeder total in spring and summer. Even committed foragers, though, seldom replace more than a modest share of a laying ration, and winter range offers almost nothing — do not cut feed because the flock looks busy outdoors. In confinement, by contrast, the full quarter pound must land in the feeder, and bored Leghorns in tight runs do better with the ration split between a feeder and a scattered portion to work for.
Feeding a Mixed Flock Fairly
Where Leghorns share a run with heavier breeds, the problem is access, not amount. Flighty Leghorns are quick but easily displaced at a single crowded feeder by larger hens, so provide more than one feeding station, spaced apart, and watch the smallest birds eat undisturbed. Check crops at roosting time on a few evenings: a full, rounded crop means that bird found her share; repeatedly empty crops on the same hens mean the feeding layout, not the ration, is failing them. Pellets reduce selective feeding compared with mixed grain, which Leghorns will otherwise pick through for favourites.
When Feed Intake Drops Across the Pen
A flock-wide dip usually has a keeper-side cause — stale or damp feed, empty or fouled drinkers, a heat wave, or a fright from a predator visit — so audit the setup before changing rations. An individual Leghorn eating little, sitting hunched, or producing thin-shelled eggs repeatedly deserves closer checks and veterinary advice if she does not rally within a day or so, since laying breeds work hard and decline fast.
