Americans dine on white and dark turkey meat at Thanksgiving, with some using the giblets for stuffing. Still, even on turkey day, most people start their morning with chicken eggs. Why are turkey eggs so unpopular?
Because they're expensive. Chicken hens are egg-laying dynamos, dropping one almost every day, while a turkey produces only about two per week. Chickens begin laying eggs at about five months of age, but turkeys don't have their first cycle until more than two months later.
Commercial egg producers typically, although controversially, allocate less than 50 square inches of space to a hen. Turkeys are given more than 3 square feet, enough to accommodate eight chicken hens. Turkeys also require more food than chickens.
These factors combine to make turkey eggs far more expensive than chicken eggs. A dozen chicken eggs currently cost approximately $1.61. There's no nationwide data on the cost of turkey eggs -- the USDA doesn't even have grading regulation -- but many producers sell them for $2 to $3 per egg.
Turkey eggs used to be a menu staple in North America. Archaeologists have found turkey-egg shells at encampments of pre-Columbian Americans. Hopi Indians consider them a delicacy. (The Navajo ate only the flesh of turkeys, however.) Europeans imported domesticated turkeys in the 16th century, and the eggs were soon part of Old-World cuisine. Americans also served them until fairly recently. Turkey egg omelettes were a regular offering at New York's legendary Delmonico's restaurant in the late 19th century.
The easiest and most traditional preparation method for turkey eggs is boiling (six minutes in simmering liquid) or poaching (four minutes). Nineteenth-century chefs also believed that turkey eggs made better sauces than did the eggs of other fowl.
The basic process is to boil and dice the eggs, then fold them into a Bechamel sauce. Alexis Soyer, the most celebrated culinary professional in Victorian England and arguably the English-speaking world's first celebrity chef, claimed that turkey eggs were better in baked goods than chicken eggs. (You have to adjust for their size, of course.)
Turkey eggs have been the subject of slander on the continent -- French commentators in the 1500s and 1600s claimed that the eggs caused leprosy. (In fact, the microbe Mycobacterium leprae causes the disease. Armadillos transmit the pathogen to humans, but turkey eggs do not.)
Turkey eggs contain most of the same nutrients as chicken eggs, but are richer.
The average turkey egg is 50 percent larger than a chicken egg, but contains nearly twice as many calories and grams of fat and four times as much cholesterol.
Duck and goose eggs also contain more fat and protein, which is one reason why most people find "exotic" eggs more flavorful than the ubiquitous chicken egg.
