For what it is worth, "easter" is a word derived from a word with meanings of  "spring" and "fertility". The date is chosen according to lunar cycles. A little research will show that the church has adopted the term, perhaps like Christians claimed the winter solstice time as a time to celebrate the birth of Jesus. It was a way to compete with old religions. Considering all that, the bunny seems to be as genuine a derivative as the resurrection of Jesus.

Don't get me wrong. I have been a Christian all my life, but I want to be an effective one, and one who can accept that not everything is about me and Jesus.(I think that's what Jesus would want)
