The document outlines the life cycle of a chicken from egg to hatching. It begins with an introduction to a class project to hatch chicks. The eggs are kept warm for 21 days either under a hen or in an incubator. An incubator keeps the eggs at the correct temperature for growth. After 21 days, the chicks will hatch by pecking at their shells. They are wet when they first hatch but their feathers dry quickly. The new chicks must be kept warm for several weeks under an infrared lamp.
