The History of the Jersey Giant Chicken


The Jersey Giant got its start in the late 1800s, at a time when chicken and turkey dinners were a luxury most families saved for holidays. Birds back then ate a lot and grew slowly, which made raising them to table size expensive. Two brothers from New Jersey set out to change that. Between 1870 and 1880, John and Thomas Black crossed several large breeds, including Langshans, Dark Brahmas, and Javas, to create the bird we now call the Jersey Giant. Their goal was a chicken meaty enough to rival the turkey on the dinner table.

The breed was originally known as the Black Jersey Giant, named in honor of the Black brothers rather than its dark feathers. They succeeded in building a truly massive bird, though their timing worked against them as a commercial venture. Today the Jersey Giant is treasured less for the meat market and more as a gentle, productive addition to the backyard.

Just How Big Are Jersey Giants?

Size is the first thing people notice. The Jersey Giant is the largest purebred chicken breed in the United States. Under the breed standard, roosters can reach up to 13 pounds and hens around 10 pounds, though hatchery birds often mature closer to 8 to 9 pounds. Either way, these are big, heavy birds, often a third larger than most other heavy breeds.

All that weight comes with a practical upside. Jersey Giants are too heavy to be strong fliers, so a modest fence is usually enough to keep them where you want them. That makes them easier to contain than lighter, flightier breeds that can clear a tall fence the moment something spooks them. For many backyard keepers, a calm bird that stays put is exactly the point.

Jersey Giant Temperament: Gentle by Design

The mellow personality of the Jersey Giant is not an accident. The breed’s founders deliberately selected for a calm, docile temperament because small flock owners of the era valued birds that were easy to manage. More than a century later, that gentle nature still defines the breed. Jersey Giants are easy to handle, tolerant of being picked up, and generally peaceful with the rest of the flock. Their size and steady disposition also make them a favorite with families and with children learning to care for chickens.

Black, White, and Blue Jersey Giant Varieties


Jersey Giants come in three recognized colors, and each has its own appeal. The original Black Jersey Giant wears glossy black feathers with a striking green sheen in sunlight. The White Jersey Giant gleams bright and clean against a green yard, while the rarer Blue Jersey Giant shows off soft, slate-blue plumage.

Here is a fun detail rooted in history. Beneath their black feathers, Jersey Giants have yellow skin and bright yellow foot bottoms. Back when the breed was developed, American diners preferred poultry with yellow skin, unlike English buyers who favored white skin. So a Black Jersey Giant carries black feathers and dark shanks on the outside, with that classic yellow skin underneath. Whatever the color, you can see the breed up close when you browse Black Jersey Giant chicks from Hoover’s Hatchery and the other varieties they raise.

How Many Eggs Do Jersey Giants Lay?

For such a meaty breed, Jersey Giants are pleasantly productive in the nest box. Hoover’s Hatchery reports that a Jersey Giant hen lays about 240 large to extra-large brown eggs per year. That is a respectable output, and the eggs are notably big, which suits anyone who loves a hearty breakfast.

One thing to expect is timing. Jersey Giants often start laying a little later than quicker-maturing layers like Rhode Island Reds or ISA Browns, since the breed puts its early energy into growing that famous frame. Their cold hardiness helps them keep laying as the weather turns, too. If steady brown eggs are your goal, the Jersey Giant pairs nicely with other brown egg laying breeds in a mixed flock.

Raising Jersey Giants: Growth, Space, and Care

Caring for a Jersey Giant is much like caring for any standard chicken, with a couple of size-related notes. First, patience. Jersey Giants are slow to mature, often taking eight to nine months to reach full size, and they eat a fair amount of feed to get there. That slow growth is the main reason the breed never became a commercial meat bird, but it is rarely a drawback for a backyard flock.

Because they are large, Jersey Giants may appreciate slightly bigger nest boxes and pop hole doors, though most fit comfortably in standard-sized nests. Set their roosts a little lower to the ground as well, since heavy birds can injure their feet jumping down from tall perches. The news on climate is excellent: Jersey Giants are both cold hardy and heat tolerant, and their large bodies hold warmth well through northern winters. If you are designing housing for bigger birds, our coop plans and inspiration can help you build a setup that fits them. Comparing the breed against other dual-purpose chicken breeds can also help you decide if a Giant suits your goals.

Frequently Asked Questions

Are Jersey Giants good backyard chickens?

Yes. Jersey Giants are calm, easy to handle, and cold hardy, which makes them a great fit for backyard flocks. Hens lay a steady supply of large brown eggs, and the breed’s gentle temperament suits families and beginners. The main trade-offs are their large size and slow growth, so they need a bit more feed and space than smaller breeds.

How big do Jersey Giants get?

Jersey Giants are the largest purebred chicken breed in the United States. Under the breed standard, roosters can reach about 13 pounds and hens around 10 pounds, while hatchery-raised birds often mature closer to 8 to 9 pounds. They are typically about a third larger than most other heavy breeds.

How many eggs do Jersey Giants lay?

A Jersey Giant hen lays roughly 240 large to extra-large brown eggs per year, according to Hoover’s Hatchery. They tend to begin laying a little later than fast-maturing breeds because they invest early energy in growth. Their cold hardiness helps them keep producing into cooler months.

Can Jersey Giants fly?

Not well. Because Jersey Giants are so large and heavy, they are poor fliers and rarely get far off the ground. This makes them easy to contain, since a relatively low fence is usually enough to keep them in their area.

Are Jersey Giants cold hardy?

Yes, Jersey Giants are very cold hardy. Their large body mass helps them retain heat, and they handle northern winters well. They are also heat tolerant, which makes them adaptable to a wide range of climates.

The Jersey Giant is proof that bigger can also mean gentler. You get an impressive, head-turning bird, a calm companion that is easy to handle, and a hen that fills the basket with large brown eggs. The breed may have missed its shot at commercial fame, but it found a far better home in backyards, homesteads, and small farms where heritage and personality count for more than speed. If you have the space and a little patience, a Jersey Giant or two will reward you for years.
