4’x12′ Walk In Chicken Coop Plan For 8 Chickens

Step By Step Instructions On How To Build A 4'x12' Small Sized Walk In Chicken Coop

This is a lean-to style chicken coop built tall enough to allow you to walk inside to collect eggs, feed, or clean. The coop is designed with protected areas for nesting and roosting, while still allowing space for roaming while the coop is closed. With a height of over seven feet, it provides easy access for anyone to step through the swinging front door. There are also cabinet style doors for entry into the nesting box, so egg collection and cleaning is a snap there as well.

The dimensions are 4 feet by 12 feet, providing plenty of interior room for up to 16 birds. It is a stationery design, which also allows for easy expansion by adding more coops next to each other. It should only take you four to five days to build, including time for glue to dry and insulation to be installed. It requires a medium level of carpentry skill to build, and the cost estimate of parts and material is around $600 to $700, all easily available at almost any hardware store.

It is spacious and sturdy enough not only to protect your chickens and hatchlings from predators but also to protect them from bad weather. The easy access design will let your chickens out for yard feeding, but still, provide security when you want your birds kept safely away.
