A wooden puzzle that builds an entire life cycle in four stacked layers. At the base sits a single whole egg tucked into a woven nest; the next layer up shows the shell cracked open with a hatchling pushing through; above that stands a fluffy young chick alone among daisies; and the top layer completes the story with a full-grown hen back on her own nest, surrounded by a fresh clutch of eggs, the cycle arriving right back where it started. Stacking the layers in order turns a simple puzzle into a hands-on story about how a chicken actually comes into the world: egg, hatchling, chick, hen, and eggs again. Each layer is thick enough for little hands to lift, align, and restack with ease, building real fine-motor control alongside the storytelling. It's a gentle, concrete way to introduce a real biological process to a preschooler just starting to ask where baby animals come from. Warm, hand-illustrated artwork keeps it inviting. For curious hands ages 3 and up.
