Matthew and Maggie came with their two children and a sackful of chickens. Maggie emptied the sack into the yard and three red banty chickens clucked and scattered.
"They are for you," she told Sarah. "For eating."
Sarah loved the chickens. She clucked back to them and fed them grain. They followed her, shuffling and scratching primly in the dirt. I knew they would not be for eating.
This is from the novel "Sarah, Plain and Tall". Did Maggie think the chickens were for eating but Sarah didn't? Or is it about their eggs? Or Is it a Joke?
