A Hole Under the Henhouse (Paperback) (ISBN-13: 9798233525070)

Wren and Ellis are siblings running a small egg subscription service on their family's regenerative ranch (think: chickens in a mobile coop called the "Egg-Mobile"). Business is booming until their top-producing hen, General Eggers, starts laying lopsided, paper-thin eggs. Then, the feathers start disappearing. And then, the feed bill goes up without them feeding more.
