9’x42′ Chicken Run Plan

Introduction

This plan is for an extra large chicken coop with a lean-to roof design and space for up to 22 chickens. As designed, it is approximately 9 feet by 42 feet and over 9 feet in height at the front, so it is definitely going to have plenty of space for growth and ease of use. There is a large enclosed room for plenty of roosting and nesting area, and to provide for easy egg retrieval. It is one of the larger designs, so if you plan on expanding, you can save money and time by starting out with more space than you might initially need. Two different doors offer entry to the main chicken run and to the roosting area. Another hatch door on the back allows an additional way to collect eggs or access for cleaning. Windows and wire designs provide plenty of fresh air during summer months, but still, provide protection from predators and from harsh weather.

It is, of course, stationary in design, and may take a few days to build. It requires a medium level of carpentry knowledge. There is also a full web tutorial to help you through every step of the building process. If you are going to construct your own coop, and if you have plans for large-scale egg or meat production, then this is the plan for you to start with.
