Inspired by true events, One Hen tells the story of Kojo, a boy from Ghana who turns a small loan into a thriving farm and a livelihood for many. After his father died, Kojo had to quit school to help his mother collect firewood to sell at the market. When his mother receives a loan from some village families, she gives a little money to her son. With this tiny loan, Kojo buys a hen. A year later, Kojo has built up a flock of 25 hens. With his earnings, Kojo is able to return to school, and soon Kojo's farm grows to become the largest in the region. The final pages of One Hen explain the microloan system and include a list of relevant organizations for children to explore.
