Framed by the author's personal experience with backyard hens, "Chickens: Their Natural and Unnatural Histories" explores the history of the chicken from its descent from the dinosaurs to the space-age present. En route, Lembke surveys chickens in ancient Greece, the Middle Ages, the Renaissance, the nineteenth century, and modern times, including the role of chickens in Jewish and Muslim practices. She also investigates the birds' contributions to science and their jaunty appearances in literature.
