One side-benefit of our modern knowledge about the evolution of life on this planet is that we can now answer the chicken-or-egg riddle definitively, although the answer might seem like cheating to some. Clearly, there were eggs before there were chickens -- reptile eggs, that is. (Not to mention the eggs without shells laid by nearly countless species of fish.) Evolutionary biologists estimate that reptiles, with their ability to lay land-worthy eggs, have been on this planet twice as long as any birds.

A peculiarity of chicken eggs many city-dwellers do not know about is that even though chicks come from eggs, hens can lay eggs without being fertilized by a rooster. That seems counter-intuitive, given that the evolutionary value of fertilized eggs has been that of producing offspring. Nevertheless, virtually all the chicken eggs marketed by grocers today in Western societies are infertile. (In his early adulthood, Gandhi, staying in England, abstained from eating eggs so as to not take animal life -- until he was informed that those chicken eggs he was being offered could never have developed into a chick.)
Today, in watching nature shows on TV, I can experience something even more marvelous than being able to eat eggs while eating vegetarian. I can watch as mother tortoises and other turtles use their clumsy-looking hind legs to dig a pit in the sand. Then, out of their bodies emerge beautiful white ovals, looking so much like those familiar eggs we all know firsthand. As part of a long line of reptiles, that mother turtles' usually private ritual dates back over 300 million years.

Do you have any childhood memories about Easter eggs, other eggs, chicks, or chickens?

My childhood memories of Easter eggs goes back as far as my memories of Christmas gifts under the Christmas tree. Given how much kids love Christmas, that must say something about Easter!
