it really depends on the type of duck.
just like chickens, ducks of different breeds lay different sized eggs and different colors. My Muscovy eggs are HUGE and won't fit in an extra large egg carton but I hatched out some rouen eggs a couple weeks ago and their eggs were the size of an average chicken egg.
The main difference is the feel of the egg- Ducks eggs have a waxy feel to them-and their shells are aLOT thicker.
