You can probably research on the net and find all kinds of stories about the history and meaning of eggs. So I'll just relate a couple of personal stories.

I grew up dying real hard-boiled eggs usually a week (or maybe more) before Easter and then going to various organized Easter Egg Hunts, (Sunday School class, Girl Scouts, local neighborhood, etc.) Usually there were prizes for most eggs, least eggs, the golden egg, etc. When my kids were small and we lived in Alabama, we lived next door to a man who was head of the poultry farm at a university. He brought us 5 or 6 DOZEN small eggs (quail or some kind of exotic bird.) We were sick of hard boiled eggs. It was also the custom there to pickle the hard boiled eggs in beet juice and vinegar (after the hunt and hopefully before they were rotten).

Then of course on Easter morning the Easter Bunny (kinda like Santa Claus) fills the Easter baskets with candy that the kids set out the night before. That same bunny also hides their eggs (hard boiled or plastic filled with candy or chocolate). One Easter at our house the Easter Bunny overslept and my 6-year-old daughter came to my bedroom crying that the Easter Bunny forgot her. I then jumped out of bed, sent her in one direction, and THREW eggs all over the living room!

Then there was the time my daughter "proved" there was a Santa Claus because she "knew" there was an Easter Bunny and a Tooth Fairy. But that's another story.
