The tradition of decorating eggs is an ancient tradition going back as much as 5,000 years, the custom of Easter eggs started with the early christians who stained the eggs red in memory of the blood Christ shed at the crucifixion and a symbol of the resurrection.
For many years real chicken eggs were dyed and hidden for the children to find, but in today's modern world artificial eggs are used most of the time, they can be made from chocolate, or filled with candy. They are usualy hidden and in some instances prizes are given for the child who finds the most eggs. This is a much better use of the eggs, I remember wondering what to do with all those hard boiled eggs the day after Easter.
Instead of each household having their own Easter egg hunt, these events can be found in public parks, put on by churches, or sponsored by many cities.
