Easter eggs are specially ecorated eggs given to celebrate the Easter holiday or springtime. The oldest tradition is to use dyed or painted chicken eggs, but a modern custom is to substitute chocolate eggs, or plastic eggs filled with confectionery such as jellybeans. These eggs are often hidden, allegedly by the Easter Bunny, for good children to find on Easter morning. Otherwise, they are generally put in a basket filled with real or artificial straw to resemble a bird's nest.
