Duck meat is generally considered to have a richer, more flavorful profile compared to chicken. It is higher in fat, which contributes to its dense and hearty texture. Duck meat is also higher in vitamins, particularly iron and copper, and has a slightly lower cholesterol and sodium content compared to chicken.
Duck is among my favorite meats. Just delicious. My mother would make roast duck every now and then, and my wife loved it too. When we were newlyweds, my wife got a recipe from my mother for duck with an orange sauce, and made two roast ducks. I ate one, and half of the second one along with other dishes she made. She mostly just stared at me, amazed to see a human eat so much. The half that was left was more than enough for her.
Ducks do carry mites. Lake swimmers get the mites from ducks landing on the lake.
And they float, making them very popular for tropical rice paddy bug patrol. Domesticated ducks can still fly enough to evade predators. Unlike most creatures, they DON'T taste like chicken!
