Quails eggs: Smaller than chicken eggs, with speckled shells. They have higher protein and cholesterol amounts, and have a higher yolk-to-white ratio. The cholesterol they do contain is mostly the “good” kind, so they are a healthy alternative to chicken eggs. Fun fact: The spots on a quail egg are unique to each hen, like fingerprints are to a human.
Duck eggs: Larger than chicken eggs. They tend to be white, light green or even black. Their shells are also tougher which gives them a slightly longer shelf life. The yolk is darker and larger, so it’s not surprising that nutritionally you’ll also get twice the cholesterol from a duck egg than you’d get from a chicken egg. They have less water content, which means the white of the egg can be rubbery if overcooked.
