Founding Flocks, Part 5: The Jersey Giant
Some Founding Flocks breeds get by on their looks. The Jersey Giant gets by on sheer size. Developed in New Jersey in the late 1800s, it is exactly what the name promises: the biggest chicken most backyard Keepers will ever raise. Part five of our Founding Flocks series belongs to the gentle giant of the American backyard.

Top 3 Takeaways
- Built to be the biggest. Developed in New Jersey specifically to be one of the largest breeds in the country, and it still holds that reputation today.
- Slow and steady. Jersey Giants take about six months to reach full size, longer than most backyard breeds, but the wait produces a bird built to last.
- Gentle despite the size. Despite an imposing frame, Jersey Giants are calm and friendly, easy to handle even for families with kids.

Breed of the Week: The Jersey Giant
If the Wyandotte proved an American breed could be beautiful and tough, the Jersey Giant proved one could simply be enormous.
The Jersey Giant was developed in New Jersey in the late 1800s with one goal in mind: build the largest, most impressive dual-purpose chicken the country had seen. More than a century later, it still wears that title. Walk up to a full-grown Jersey Giant next to almost any other backyard breed, and the size difference does the talking.
What makes the Jersey Giant great
Size. This is the breed’s calling card. A mature Jersey Giant runs about 8 to 9 pounds, among the largest weights of any backyard breed we carry, with a broad, deep-bodied frame that fills out a coop doorway.
Temperament. For a bird this size, the Jersey Giant is remarkably easy going. It is calm and friendly, which makes it a good fit for families, including ones with kids who want to be around the flock.
Growth. Jersey Giants are slow maturing, taking about six months to reach full size. That is longer than most breeds on this list, and it is part of the trade for a bird built this substantial.
Eggs. Expect about 240 large brown eggs a year, a steady, dependable output from a dual-purpose bird that was never bred to be just a layer.
Comb. A single comb, standard across the Jersey Giant varieties.

One breed, three colors
Hoover’s carries the Jersey Giant in three varieties. All three share the breed’s defining size and gentle temperament, and differ mainly in plumage:
- Black Jersey Giant. The original color the breed is best known for, sharing the same imposing size and calm demeanor as its Blue and White counterparts.
- Blue Jersey Giant. The same large, impressive build in striking blue feathers. Slow maturing at about six months, a moderate layer of about 240 extra-large brown eggs a year, with a mature weight of about 8 to 9 pounds.
- White Jersey Giant. Smooth, pure white plumage over the same broad, muscular frame, laying about 240 large brown eggs a year, with a mature weight running about 6 to 9 pounds.
