8 x 16 Chicken Run Plan

Introduction

When you need a chicken coop that has plenty of space and function, consider this 8'X16' building some thought. With 128 square feet of interior space and an enclosed run, your birds will have room to stretch their legs and enjoy the fresh air without fear of predation. The coop has raised nesting boxes that provide safety for your hens, it's doors open from the top and make it easy for you to gather the eggs.

The roof over the enclosed run protects the birds from heavy rainstorms and strong winds. It also keeps midday sun off the birds during the summer. The roof is more than amply sized to install solar panels that could power the lights and heating system inside the coop.

Let's begin!
