Eggs are too familiar to our kitchen. We used chicken egg for breakfasts, for baking, for other meals, or many other areas. But how about duck egg, the type which nutrition content and usage is not less than chicken’s? Let take a look on this poultry egg.

Yes but there are some features differed from them. In the eggs world, duck egg is much like chicken egg as shaped and structure but larger and mostly white. Like bird eggs commonly, egg of duck also includes 4 layers: yolk, white, membrane and shell. The duck egg shell is harder than chicken and so its shelf life is longer than of chicken’s. Its size is also larger than chicken about 30-50%, and so is the yolk.
Duck egg is believed less clean than chicken egg, for the ducks are usually fed freely, and their eggs could not be gathered at the place like chicken. But possibly, besides the biological specification, the way of feeding ducks with varieties food sources in the nature could be lead to the rich nutrition of their eggs.

Besides, the smell of duck egg is a little stronger than chicken egg and some people may not like it much.
