Which Egg Has the Most Protein, Duck or Chicken?

December 16, 2025 •

2 min read

A single duck egg provides more protein than a chicken egg due to its larger size, though the protein content per 100 grams is similar. This article explores these differences.

Quick Summary

Duck eggs have more protein per egg than chicken eggs. The per-100-gram protein content is similar, though duck eggs contain more fat and other nutrients.

Key Points

Protein per Egg: A single duck egg contains more total protein (around 9g) than a large chicken egg (6-7g) because duck eggs are larger.
Protein per Weight: On a per-gram basis, the protein concentration is nearly identical for both egg types, with duck eggs containing only a fraction more.
Higher Calorie and Fat Content: Duck eggs are higher in calories, fat, and cholesterol due to their larger, richer yolks.
Nutrient-Dense: Duck eggs provide a more concentrated source of vitamins (like B12) and minerals (like iron) compared to chicken eggs.
Superior for Baking: The higher fat and protein content of duck eggs makes them ideal for baking, resulting in richer, fluffier results.
Distinct Flavor Profile: Duck eggs have a richer, creamier taste due to their proportionally larger yolk, while chicken eggs have a milder flavor.
Consider Your Dietary Goals: Choose duck eggs for maximum nutrients per egg or for baking, and chicken eggs for a lighter, more versatile, and widely available option.

The Core Protein Comparison

When evaluating which egg has the most protein, duck or chicken, it is crucial to consider two metrics: the protein content per individual egg and the protein content per an equal weight serving. Duck eggs are substantially larger than chicken eggs, leading to differences in per-egg nutrient content.

The Per-Egg Verdict

On a single-egg basis, duck eggs offer more protein. A large chicken egg provides around 6-7 grams of protein, while a duck egg contains approximately 9 grams.

The Per-Weight Analysis

Comparing equal weights of 100 grams, the protein content is very similar, with duck eggs having only a slight edge. This indicates that the higher protein in a single duck egg is primarily due to its size, not a greater protein concentration.

Beyond Protein: Key Nutritional Differences

Beyond protein, duck and chicken eggs differ in other nutritional aspects. Duck eggs are generally higher in calories and fat due to their larger yolks. They are also richer in certain micronutrients, including Vitamin B12, iron, and folate, but contain more cholesterol than chicken eggs.

Culinary Applications and Taste

The nutritional differences influence how these eggs are used in cooking and baking. Duck eggs have a richer, creamier taste due to their higher fat content and larger yolk. The higher fat and protein in duck eggs contribute to improved structure, color, and rise in baked goods, while chicken eggs offer a milder, more versatile taste.

How to Choose: Which Egg is Right for You?

The choice depends on individual dietary needs and culinary uses. Consider duck eggs for higher protein and micronutrients per serving or for baking. Choose chicken eggs for a lower-fat, lower-calorie, more widely available, and versatile option. Those with chicken egg allergies might tolerate duck eggs but should consult an allergist.

Comparison Table: Duck vs. Chicken Eggs (per 100 grams)


Nutrient	Duck Egg (100g)	Chicken Egg (100g)
Energy	185 kcal	143 kcal
Protein	12.8 g	12.6 g
Total fats	13.8 g	9.51 g
Carbohydrates	1.45 g	0.72 g
Cholesterol	884 mg	372 mg
Vitamin B12	5.4 µg	0.89 µg
Iron	3.85 mg	1.75 mg

Conclusion

While duck eggs provide more protein per individual egg due to their size, the protein concentration per gram is similar to chicken eggs. Duck eggs are richer in fat, calories, and certain micronutrients, making them beneficial for baking and nutrient density, but chicken eggs are a lighter, more versatile, and common choice. The best egg depends on your specific dietary priorities.

Frequently Asked Questions

A single duck egg contains approximately 9 grams of protein, compared to about 6-7 grams in a large chicken egg. This is mainly due to the duck egg's significantly larger size.

No, the protein content per gram is nearly identical for both eggs. The higher total protein in a duck egg is a result of its larger size and weight, not a higher protein concentration.

Yes, duck eggs have higher levels of fat, cholesterol, and calories. They also contain more concentrated amounts of certain micronutrients, including vitamin B12, iron, and folate.

Bakers often prefer duck eggs because their higher fat and protein content, along with less water, results in richer flavor, better structure, and a superior rise in baked goods.

Duck eggs have a richer, creamier flavor than chicken eggs due to their larger yolk and higher fat content. Chicken eggs have a milder, more standard egg flavor.

Yes, but with some adjustments. Since duck eggs are larger, you may need to use fewer duck eggs to achieve the same volume. Their richer composition can also alter the final product's texture and flavor.

Whether a duck egg is 'healthier' depends on your goals. Duck eggs are more nutrient-dense and have more protein per egg, but they are also higher in calories, fat, and cholesterol. The best choice depends on individual dietary needs.
