A typical 1 egg serving of quail egg contains 1.2 grams of protein (13 g per 100 g), which makes it only a minor source of protein. That covers roughly 2% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Protein accounts for roughly 33% of the calories in quail egg, making it moderately protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Among the 20 eggs in the database, quail egg ranks 20th by protein per serving, and 712th out of all 796 foods on the site. Set against egg yolk, another egg entry in the database, a serving carries about 1.5 g less protein (egg yolk has 2.7 g per 1 large).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is counted by piece at 9 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
Quail eggs are tiny, so several are needed to match one chicken egg.
