The Brahma and Jersey Giant breeds are known for laying some of the largest eggs among chicken breeds, often exceeding 2 ounces each.
If you’re looking for chickens that produce jumbo-sized eggs, certain breeds stand out from the flock. While all hens start small, mature birds from specific breeds consistently lay larger eggs perfect for baking and cooking. Let’s explore the best egg-laying champions.
What Determines Egg Size?
Egg size depends on several factors:
- Breed genetics – Some breeds naturally produce larger eggs
- Hen age – Older hens typically lay larger eggs
- Diet – Proper nutrition supports egg development
- Environment – Low-stress conditions promote better laying
According to Cackle Hatchery, egg sizes are classified by weight from peewee (15 oz/dozen) to jumbo (30 oz/dozen).
Best Brown Egg Layers
Rhode Island Reds
These hardy dual-purpose birds consistently lay large to extra-large brown eggs. They’re excellent for backyard flocks and live 5-8 years with proper care.
Black Copper Marans
Prized for their dark chocolate-colored eggs, Marans often produce jumbo eggs that won’t fit standard cartons. Their eggs are among the largest brown eggs available.
Barred Rocks & Buff Orpingtons
Both breeds are reliable layers of large brown eggs. Orpingtons are particularly cold-hardy, making them great for northern climates.
Best White Egg Layers
White Leghorns
The undisputed champions of white egg production, Leghorns lay large to extra-large eggs nearly daily. They’re smaller birds that convert feed efficiently into eggs.
California Whites
This Leghorn hybrid often surpasses its parent breed in production. They’re calmer than pure Leghorns while maintaining excellent egg size.
Hybrid Power Layers
ISA Browns & Red Sex Links
These hybrids consistently produce jumbo eggs, often requiring special cartons. They’re prolific layers but don’t breed true, so they’re best for egg production only.
Black Minorcas
Known for laying exceptionally large eggs relative to their body size. Some Minorca eggs can be as large as an adult’s fist.
Maximizing Egg Size
To get the largest eggs from your flock:
- Choose breeds known for large eggs
- Provide high-protein layer feed (16-18% protein)
- Ensure constant access to clean water
- Maintain low-stress conditions
- Allow hens to mature – egg size increases with age
As noted by Backyard Chickens, hens typically reach peak egg size at 2+ years old.
Egg Size Comparison Table
| Breed | Egg Color | Typical Size | Annual Production |
|---|---|---|---|
| Rhode Island Red | Brown | Large-XLarge | 250-300 |
| Leghorn | White | Large-XLarge | 280-320 |
| ISA Brown | Brown | XLarge-Jumbo | 300+ |
| Black Copper Marans | Dark Brown | XLarge-Jumbo | 150-200 |
Caring for Heavy Layers
Chickens that lay large eggs need special attention:
- Provide extra calcium (oyster shell) to support eggshell formation
- Watch for watery egg whites, which can indicate nutritional issues
- Ensure nest boxes have plenty of soft bedding to prevent cracks
- Collect eggs frequently to discourage egg-eating behavior
With proper breed selection and care, you can enjoy a steady supply of large, delicious eggs from your backyard flock.
