Easter eggs & spring chicks
The "egg" and "spring chicks" was a fertility symbol used by many peoples dating back many thousands of years. The egg as a fertility symbol, was also important too, and as people started to keep domestic fowl, such as chickens, the observation of hen's eggs hatching bringing forth yellow coloured chicks was interpreted into their celebrations as the "sun" being re-born.
Today, an egg is a symbol of the rock tomb out of which Christ emerged when he arose again. The chick, hatching out of the egg, symbolizes new life or re-birth.
