Breeds like the Rhode Island Red, Leghorn, and Sussex are known for laying large eggs, making them popular choices for egg production.
If you’re raising chickens for eggs, size matters. Large eggs are preferred for baking and cooking, and some breeds consistently produce bigger eggs than others. Whether you’re a backyard chicken keeper or a small-scale farmer, choosing the right breeds can make all the difference in your egg production.
What Determines Egg Size in Chickens?
Egg size is influenced by several factors including breed, age, diet, and environment. While all hens start laying small eggs when they begin production, most will gradually increase egg size as they mature. Some breeds naturally produce larger eggs than others due to their genetics and body size.
Egg Size Classifications
| Size | Weight per Dozen | Weight per Egg |
|---|---|---|
| Peewee | 15 oz | 1.25 oz |
| Small | 18 oz | 1.5 oz |
| Medium | 21 oz | 1.75 oz |
| Large | 24 oz | 2 oz |
| Extra Large | 27 oz | 2.25 oz |
| Jumbo | 30 oz | 2.5 oz |

Factors That Affect Egg Size
Age of the Hen
Young hens typically lay smaller eggs when they first start producing. Egg size increases as the hen matures, usually peaking at about 1-2 years of age.
Nutrition
A balanced diet with adequate protein (16-18%) is essential for large egg production. Calcium is particularly important for strong shells. Learn when to feed chickens grit.
Environment
Stress from predators, overcrowding, or extreme temperatures can reduce egg size. Proper coop size and protection from the elements help maintain production.
Egg Color Variations
While egg size is important, many chicken keepers also enjoy variety in egg colors:
- White: Leghorns, California Whites
- Brown: Rhode Island Reds, Orpingtons, Sussex
- Blue/Green: Ameraucanas, Easter Eggers
- Dark Brown: Marans, Welsummers
Maximizing Egg Production
To get the most large eggs from your flock:
- Provide 14-16 hours of light daily during shorter days
- Keep fresh water available at all times
- Use high-quality layer feed
- Maintain clean nesting boxes
- Collect eggs frequently to prevent breakage

Special Considerations for Large Egg Layers
Chickens that lay large eggs may be more prone to certain health issues:
- Egg binding (dystocia) in smaller-framed hens
- Higher calcium requirements
- Potential for more shell abnormalities
Monitor your flock closely and provide oyster shell free-choice to support their increased calcium needs. If you notice watery eggs, it may indicate a nutritional deficiency.
Final Thoughts on Large Egg Layers
Choosing chicken breeds that naturally lay large eggs can make your backyard flock more productive and satisfying. Whether you prefer the classic Rhode Island Red, the prolific Leghorn, or the gentle Orpington, each breed offers unique advantages. Remember that proper care, nutrition, and housing will help your hens reach their full egg-laying potential.
