Some say that Egg-rolling is a symbolic game representing the rolling away of the stone at Jesus' grave or tomb. Or others say that a rabbit emerging from his burrow is a symbol of Christ rising from his tomb on Easter morning. According to German folklore, the Easter Bunny lays them and hides them in gardens. The story in France is that the eggs are dropped by the church bells on their way back from Rome. First of all, rabbits are not hares.
Hares are rabbits cousin who have shorter ears and longer hind legs.
But as long as it hops, children are not fussy. Old folklore says that witches had the power to turn themselves into rabbits. And, with the rabbits well-known reproductive skills, it is a popular Spring fertility symbol. This is why a rabbit's foot in old folklore magic is believed to have sexual potency and magical powers of financial prosperity. Sigmund Freud said that feet have sexual symbolism.
