Leghorn Chickens: Breed Facts, White Eggs, Temperament and History

Field guide · Updated October 18, 2026 · about 8 min read

The Leghorn is a light, active Italian breed kept almost entirely for eggs, and the bird behind most of America's white eggs. Mississippi State Extension calls Leghorns "usually the best overall egg layers"; The Livestock Conservancy notes that industrial Leghorns dominate American white-egg production, while smaller non-industrial flocks keep the older type going. This page collects the standard facts, the egg figures each source reports, and what the breed's energy means for a backyard flock.

Quick facts

Appearance

Oklahoma State and Purdue Extension describe red wattles, white earlobes and either a single or a rose comb; skin is yellow. The Livestock Conservancy adds orange or red eyes, a yellow beak, clean (unfeathered) legs and four toes, on a game-bird-like body with a narrow breast and an upright stance. White is the most common color (University of Georgia), but Oklahoma State lists 13 American varieties: single and rose comb in Dark Brown, Light Brown, White and Buff, plus single-comb Black, Silver, Red, Black Tailed Red and Columbian.

Standard weights make the Leghorn a small, light standard-size bird: a 4.5 lb hen against 6.5 lb for a Rhode Island Red. Mississippi State gives adults at 4.5–5.5 pounds, and The Livestock Conservancy matches Oklahoma State's 6 lb male and 4.5 lb female.

Eggs: how many, and why the numbers differ

Every source treats the Leghorn as a layer first; the counts differ. The University of Georgia calls Leghorns "the ultimate egg producing machines," and The Livestock Conservancy's comparison chart says the breed "produces more eggs with less food than any other breed." Strain is one likely reason for the spread: the commercial Single Comb White Leghorn in Oregon State's figure is an industrial line, while the Conservancy's figures describe non-industrial birds. Sources also disagree on egg size, from medium to large (University of Georgia; Conservancy chart) to large to extra-large (Conservancy breed page).

Oregon State adds that backyard breeds generally lay fewer eggs than commercial Leghorns. Laying also falls as hens age; see how long hens keep laying, or estimate your own flock with the egg production calculator, which has a commercial White Leghorn setting.

Leghorns are also light eaters. Georgia Extension calls them "economical eaters," the Conservancy calls them small eaters on range, and Mississippi State says white-egg hens are usually smaller, eat less feed and are preferred by the commercial industry because they cost less to keep. Shell color, Mississippi State adds, "has absolutely nothing to do with the nutritional content or taste of the egg." Hens still need a complete layer ration; see feeding laying hens.

Temperament and space

This is where the sources line up most clearly, and where the breed differs most from calm, heavy breeds:

• Active and noisy. Oklahoma State calls them small, lively and noisy birds that like to move around; Georgia Extension says they are "noisy and nervous and usually avoid human contact."
• Fliers and foragers. Oklahoma State and Purdue Extension say they can fly considerably, will roost in trees if allowed, and can glean much of their diet from fields and barnyards.
• Room to move. The Livestock Conservancy says they can get bored in small spaces and need room to roam and a large coop with enrichment. They will scratch up gardens and compost alike.
• Flock mates. Not aggressive by nature, but the Conservancy advises keeping them with similarly active breeds rather than docile ones.
• Not mothers. Hens rarely go broody (Oklahoma State; Oregon State), so eggs for hatching need an incubator or a broody hen of another breed (see broody hens). The Conservancy adds that chicks are easy to raise and feather quickly.

The two Conservancy pages disagree on who the breed suits: its comparison chart rates the non-industrial Leghorn for novice to intermediate keepers, while its breed page does not recommend it for first-time keepers, for children or for people who want a cuddly pet, and because of the noise, not for urban or suburban settings.

Climate: heat yes, cold with care

Georgia Extension lists Leghorns as heat tolerant, and Oklahoma State notes that the larger combs and wattles of small breeds like Leghorns help them tolerate heat better (see heat stress). Mississippi State says Mediterranean breeds generally do better in hot climates. The trade-off is winter: Kentucky's Jacquie Jacob says any hen with a large comb, "such as a leghorn," can be vulnerable to frostbite, and Maryland Extension names Leghorns and Minorcas among the Mediterranean breeds at risk. The Conservancy breed page calls the breed tolerant of both cold and heat but says rose-comb birds handle cold better; its comparison chart says "best in hot to moderate climates." In cold regions, read winter care on ventilation and frostbite.

History

APA dates are from The Livestock Conservancy. Today, Oklahoma State calls Leghorns and their descendants the most numerous breed in America, and Mississippi State notes that White Leghorns are layer chickens in many countries.

Is it a fit for your flock? A checklist

1. You want the most white eggs for the least feed. That is the breed's purpose in every source above.
2. You have room and tolerant neighbors. Plan for noise, flying and a bigger run; check local rules and size the coop with the coop space calculator.
3. You don't need a pet or a mother hen. Leghorns tend to avoid handling and rarely go broody.
4. Hot summers, or cold with a plan. In hard winters, consider a rose-comb variety and good ventilation.
5. Ask the seller which line. Commercial and non-industrial Leghorns differ in laying and type.
6. Compare breeds. See the breed directory, the Rhode Island Red and the egg color chart.
