Make way for Ducklings is one of our favorite books. There were 8 chicks in that book if my memory serves me correctly - Jack, Kack, Lack, Mack, Nack, Ouack, Pack and Quack. So we would have to add one more: Rack? (Or is that just silly?)
Two of these chicks were yellow and the others were a grey/white/yellow mix. But not one looks like its Mama! Emily and I watched these ducks for about half an hour. We noticed that one of the yellow ducks was always the straggler and one of the multi-colored ducks was either lazy, sick or tired because he was always sitting down in the grass for as long as he could before moving along with the group. We'll keep tabs on them!
