What Easter tradition involves searching for hidden decorated eggs?

The Easter tradition involving a search for hidden decorated eggs is an Easter egg hunt.

In an Easter egg hunt, decorated eggs or egg-shaped treats are hidden for children or families to find. Modern hunts often use hollow plastic eggs filled with candy, small toys or clues, while older versions used hard-boiled or painted eggs. The activity is especially common in the United States, Britain and other countries with Christian Easter traditions.

Eggs became Easter symbols through associations with new life and, historically, with the end of Lenten restrictions on eating eggs. The hunt itself is a later festive game rather than a biblical event. It is also different from egg rolling, in which eggs are rolled down a slope, and egg tapping, in which participants strike eggs together to test whose shell remains unbroken.
