4 x 8 Chicken Run Plan

Introduction

If you live in a mild climate and your chickens can enjoy the outdoors year-round, think about building this 4 x 8 chicken run with a raised shelter for roosting and egg laying. It's fully enclosed in screen to keep out predators and confine the chickens in a safe space. This coop has a human-sized entry door that opens into the outdoor space and another that opens into the coop's raised shelter. The birds can access the coop from a small ladder and door inside the run.
This building is easy to construct, doesn't require a lot of materials and provides all the shelter your birds need in mild climates. When it's safe to do so, the chickens will be able to make an easy exit from the run to explore the world outside.

Let's begin!
