If you’ve ever wondered what it’s like to own a chicken the size of a small turkey, meet the Jersey Giant—a breed so large and friendly it’s often called the “gentle giant” of the poultry world.
Whether you’re raising chickens for meat, eggs, or companionship, this breed’s calm demeanor and impressive size make it a standout choice.
In this guide, we’ll dive into everything you need to know about Jersey Giant chickens, from their history to practical care tips.
What Is a Jersey Giant Chicken?
The Jersey Giant holds the title of the world’s largest chicken breed, with roosters weighing up to 13 pounds and hens around 10 pounds.
Developed in the late 1800s, these birds are dual-purpose, excelling in both meat production and egg-laying.
Their glossy black feathers (though white and blue varieties exist) and stately appearance make them a striking addition to any flock.
A Brief History of Jersey Giants
The breed was created in Burlington County, New Jersey, by brothers John and Thomas Black. Their goal? To develop a chicken large enough to replace turkeys as the primary meat bird.
By crossing Dark Brahmas, Black Javas, and Langshans, they succeeded in creating a massive, slow-maturing bird.
Despite their size, Jersey Giants never surpassed turkeys in commercial meat production due to their longer growth period.
However, they gained a loyal following among small farmers and backyard enthusiasts for their gentle nature and reliability.
Why Choose Jersey Giant Chickens?
1. Gentle, Docile Temperament
Jersey Giants are famously calm and friendly. They’re easy to handle, rarely show aggression, and get along well with children and other pets.
Real-Life Example:
Sarah Miller, a homesteader in Vermont, shares: “Our Jersey Giant rooster, Titan, is like a feathery watchdog. He’s protective but never aggressive. The hens follow him around like he’s their gentle leader.”
2. Dual-Purpose Excellence
- Meat: Their size provides ample, flavorful meat—though they take 6–9 months to mature (compared to 8 weeks for Cornish Cross).
- Eggs: Hens lay 150–200 large brown eggs annually, even in winter.
3. Cold-Hardy and Resilient
Thick feathers and sturdy frames help them thrive in colder climates. They’re less prone to frostbite than breeds with large combs.
Caring for Jersey Giant Chickens
Housing Requirements
- Space: Allow 4–5 sq ft per bird in the coop and 10 sq ft in the run. Their size demands extra room!
- Roosts: Use wide, low roosts (12–18 inches high) to prevent leg strain.
- Nesting Boxes: Provide large boxes (14x14x14 inches) to accommodate their bulk.
Diet & Nutrition
- Chicks: Feed 20–22% protein starter crumble for the first 12 weeks to support growth.
- Adults: Switch to 16% protein layer pellets and supplement with calcium (oyster shells) for strong eggshells.
- Treats: Offer leafy greens, mealworms, and scratch grains in moderation.
Pro Tip:
Avoid overfeeding—Jersey Giants can become obese, leading to joint issues.
Health Considerations
- Leg Health: Add probiotics to feed and provide clean, dry bedding to prevent bumblefoot.
- Parasites: Dust baths with diatomaceous earth help control mites and lice.
- Molting: Increase protein intake during feather regrowth (e.g., sunflower seeds).
Jersey Giants vs. Other Large Breeds
| Breed | Weight (Rooster) | Eggs/Year | Temperament | Best For |
|---|---|---|---|---|
| Jersey Giant | 11–13 lbs | 150–200 | Calm, friendly | Meat, eggs, families |
| Brahma | 10–12 lbs | 140–180 | Docile, fluffy | Cold climates |
| Cochin | 8–11 lbs | 120–160 | Broody, gentle | Ornamental flocks |
| Orpington | 8–10 lbs | 180–220 | Affectionate | Egg production |
Key Takeaway:
Jersey Giants outsize all others but grow slower. Brahmas and Cochins are better for ornamental purposes, while Orpingtons lay more eggs.
Breeding Jersey Giants
Selecting Breeding Stock
- Choose birds with deep, broad bodies and shiny, uniform feathers.
- Avoid roosters with leg weakness or uneven combs.
Incubation & Rearing
- Eggs take 21 days to hatch.
- Chicks grow slower than most breeds—be patient! They’ll reach full size by 9–12 months.
