Brown Leghorn Chicken
Brown Leghorn
The Leghorn chicken Chicken, admitted to the American Standard of Perfection in 1874, has its origins in Italy, Denmark, and England. This breed is known for its athleticism, early maturity, hardiness, and non-brooding nature, making it an excellent layer of large to extra-large white eggs. Leghorns are prolific egg producers, often laying around 280 eggs annually, with some reaching up to 300-320. With a highly efficient feed-to-egg conversion ratio, these chickens require only about 125 grams of feed per day.
Leghorns Chicken are ideally suited for free-range farming or organic egg production due to their active and efficient foraging skills. Their lack of broodiness ensures continuous egg production, making them a reliable choice for those focused on egg-laying rather than meat production. Though light in weight and not typically raised for meat, Leghorns are quick to mature and are exceptional at avoiding predators, making them one of the best choices for free-range environments. However, they tend to be nervous and flighty, often avoiding human contact.
The Brown Leghorn is just one of the many heritage chicken breeds available at The Chicken Coop Company, perfect for those seeking high-quality, heritage chickens.
Health and Care:
-
Hardy and Adaptable: Brown Leghorns are hardy birds that can thrive in a variety of climates. While they are particularly well-suited for warmer climates due to their lean physique and light feathering, they can also handle cold weather with proper shelter and care. During extreme cold, providing a dry, draft-free environment is important for their well-being.
-
Disease Resistance: Brown Leghorns are generally healthy and disease-resistant. However, like all chickens, they can be susceptible to common poultry diseases such as mites, lice, and respiratory infections if their environment is not clean. Keeping their coop clean, ensuring good ventilation, and providing access to fresh water will help maintain their health.
- Low Maintenance: This breed is relatively low-maintenance in terms of daily care. They require a balanced diet, clean water, and a secure environment. Brown Leghorns are hardy foragers, so they do well in free-range conditions where they can explore and forage for food.

Egg Laying:
-
Excellent Egg Production: Brown Leghorns are prolific egg layers, producing around 250-300 eggs per year. These eggs are typically medium to large in size and are white, similar to the White Leghorn.
-
Year-Round Laying: Like other Leghorn varieties, Brown Leghorns are excellent year-round layers. While egg production may decrease slightly in the winter due to shorter daylight hours, they generally continue laying consistently throughout the year.
- Large White Eggs: The eggs laid by Brown Leghorns are large, white, and highly valued in the egg market. Their consistent egg production, combined with their large egg size, makes them a popular choice for both small and large-scale egg producers.

Temperament:
-
Active and Independent: Brown Leghorns are very active and curious chickens. They love to explore their surroundings and forage for food, making them ideal for free-range environments. However, this active nature can also make them more flighty and nervous compared to other chicken breeds, so they may not be the best choice if you’re looking for a calm, docile pet.
-
Not Very Affectionate: While they are generally not aggressive, Brown Leghorns tend to be more independent than other chicken breeds. They aren’t as affectionate or social with humans, so they may not enjoy being handled frequently. However, they are not known for being overly aggressive or territorial, which makes them suitable for larger flocks.
- Flighty and Nervous: Like the White Leghorn, Brown Leghorns can be flighty and skittish, which makes them harder to handle, especially for those new to keeping chickens. This breed is often more interested in foraging and exploring than interacting with people.
Frequently Asked Questions:
What color eggs do Brown Leghorns lay?
Brown Leghorns, renowned for their beautiful feather patterns, lay white eggs. They possess the same productive qualities and energetic nature as their white counterparts but feature slightly larger bodies adorned with striking feathers.
How do Brown Leghorns differ from White Leghorns?
The primary difference between Brown and White Leghorns is size. Brown Leghorns are considerably larger. For instance, while I can easily hold a White Leghorn upside-down in one hand, this isn't possible with a Brown Leghorn. Save the image below for a handy reference.
What is the lifespan of Brown Leghorns?
Brown Leghorns, like many high-egg-laying breeds, have a relatively short lifespan, typically around 6 years. Their rapid egg production contributes to this shorter life span. As with all pet birds, they are susceptible to lice and mites.
Do Leghorns grow quickly?
White Leghorns are especially useful for research due to their rapid growth and high sensitivity to changes in diet or environment. They mature quickly, often within less than a year, making them a model for various studies.
Are Brown Leghorns aggressive?
Generally, Brown Leghorns are not aggressive. However, if you're integrating them into a mixed flock, it’s best to pair them with breeds of similar temperament rather than more docile varieties.
