When you compare a duck egg to a chicken egg, you will immediately notice that a duck egg is bigger than a chicken egg. Tests have also been done and it is a fact that a duck egg is more nutritious then a chicken egg. Break the two eggs and you will also see that the yolk of a duck egg is firmer and better looking than a chicken egg. If you cook the two eggs, you will find that duck eggs taste better than chicken eggs.
But let me ask you, which egg sells better? Chicken eggs or duck eggs? Answer? Chicken eggs. Why?
Because when a duck lays an egg, there is no excitement. A hen laying an egg, on the other hand, will flap her feathers, fly around and holler, as if to tell everyone, “I've laid an egg! I've laid an egg! Come and buy.”
Story I use on the importance of being excited. You can buy many books on personal improvements and most writers will tell you one of the most important ingredient to success is enthusiasm. Eddy Chai
