Duck eggs look like chicken eggs, but are larger: As with chicken eggs, they are sold in sizes ranging from small to jumbo. The egg white is more transparent, without the yellowish tinge of a chicken’s white. Duck eggs have more protein and more flavor/richness than chicken eggs, but they also have a higher fat content and more cholesterol. When boiled, the white turns bluish and the yolk turns red-orange. See a full nutritional comparison of chicken and duck eggs.
