Soup for the chickens

In the tub this morning, the girls kept making soup for the chickens. Now this has happened the last three baths, and I was curious. I racked my brains... was it in a book? Something they picked up at Auntie Jo's? Where did this come from? Oh yeah, Francis and I had talked about how the laying birds were slowing down and it was time to make chicken soup. Chicken soup -soup for chickens. Oh, the innocence of youth! Who's going to tell them that the chickens aren't coming for dinner, but they are dinner?
