I hope they give you an Easter suprise! When I was a kid we got a pair of mallard ducklings for Bunny Day. Around St. Pats Day the next year in a similar experience to what your boys had, I stumbled onto a nest of about 20 eggs back by the woods. Abracadabra! I remember the excitement from observing their lifecycle first-hand. I'll be looking forward to seeing your little waddlers running around!
