30 x 15 Walk In Chicken Coop Plan

Introduction

This is a plan for a large, 30x15 chicken coop that can house up to fifty birds. It is of some complexity to build and set on a permanent foundation. However, this design can really prepare your operation to be ready for any level of expansion. The size of the house and the total area can house even the largest flock. With two separate cage spaces, there is plenty of room for roaming. Meanwhile, the henhouse is walk-in with a full-sized door. This allows easy access to cleaning, feeding, egg collection, and hatchling harvest. With proper insulation and the installation of approved heating, this coop design can protect your chickens during even the harshest winter. The slanted roof design can keep your birds dry in even the heaviest rain storms with the use of corrugated boards and proper painting and maintenance.

The interior allows for lots of nests in a simple to access roosts. The dual aviary design helps you easily separate the birds, especially for thorough cleaning. With entry doors on both sides, both you and your chickens can enter the aviaries with ease. Access windows on the side of the henhouse allow for free flow of air during warmer months.
