Twelve-year-old Sophie Brown feels like a fish out of water when she and her parents move from Los Angeles to the farm they've inherited from a great-uncle. But farm life gets more interesting when a cranky chicken appears and Sophie discovers the hen can move objects with the power of her little chicken brain: jam jars, the latch to her henhouse, the entire henhouse .And then more of her great-uncle's unusual chickens come home to roost. Determined, resourceful Sophie learns to care for her flock, earning money for chicken feed, collecting eggs. But when a respected local farmer tries to steal them, Sophie must find a way to keep them (and their superpowers) safe.

Through a series of letters, twelve-year-old Sophie Brown tells of her family's move to Great-Uncle Jim's farm, where she begins taking care of some unusual chickens with help from neighbors and friends.
