Duck eggs

[seal!]

How different are they from chicken eggs?

[Narolines]

Bigger, and stronger, richer flavour.

when they hatch, you get ducklings instead of chicks. (sorry)

[CorinnaJ]

The shells are more porous so they do not last as long.  This is why they do not sell them in most shops - hen eggs have a much longer shelf life.

When you hit 'em with your spoon, they quack !

[Beswad]

Taste wise, duck eggs are quite bland compare to chicken eggs and chicken egg yoke have more aroma.
