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.
Materials you’ll need
Step 1 – Foundation Preparation
1.1 Clear and align the ground according to the dimensions in the drawing.
1.2 For the foundation, dig the trenches at least 1′ wide and 1′ deep.
1.3 Fill the trenches to ground level with concrete and let cure, or harden. Since curing times vary between brands, read the packaging for recommended curing times.
1.4 Once the concrete has cured, use standard-sized bricks and lay them across the foundation. You will need roughly 90 bricks for this step.
Step 2 – Assemble The Bottom Frame
2.1 Assemble the frame using 3 1/2″ x 3 1/2″ pressure-treated material. You will need two boards cut to 9′ that will be the joists, eight boards cut to 10′-3″ that will be the rim joists and one board cut to 8′-5″ that will be the joist.
2.2 For the corners use an overlapping joint.
2.3 Secure the beams into the frame with 2×3″ wood screws.
2.4 Using a speed square or carpenter’s square, check the corners to make sure they are 90 °.
Step 3 – Assemble The Wall Studs
3.1 Using 3 1/2″ x 3 1/2″ pressure-treated material, cut nine 8′-4″ length studs, nine 7′ length studs and assemble using the illustrations below as a reference.
3.2 Use 4 1/2″ x 4 1/2″ x 1/2″ corner braces and 8×1″ wood screws to secure the corners.
3.3 Make sure the corners are 90° using a carpenter’s square or speed square.
Step 4 – Assemble The Roof Frame
4.1 Prepare 18 rafters with cross-section 1 1/2″ x 5 1/2″.
4.2 Connect the beams to the top frame with the help of 2″ x 2″ x 3/4″ corner braces, hurricane ties, and 1″ wood screws.
Step 5 – Assemble Inner Wall Frame
5.1 Using 1 1/2″ x 3 1/2″ pressure-treated material, cut seven studs 7′ length and construct an inner wall frame using the drawing below as a reference.
5.2 Connect the beams with 2×3″ wood screws.
5.3 Using a speed square or carpenter’s square, check the corners to make sure they are 90°.
Step 6 – Framing The Right Wall
6.1 Using 3 1/2″ x 3 1/2″ pressure-treated material, cut two joists and attach them using the illustration below as a reference.
6.2 Use 4 1/2″ x 4 1/2″ x 1/2″ corner braces and 1″ wood screws to secure the bottom girt.
6.3 Secure the studs with 4×5″ wood screws.
Step 7 – Nesting Box Assembly
7.1 Using 1 1/2″ x 2 1/2″ material, assemble the frame for the nesting boxes using the illustration below as a guide. Make sure to take note of the 9° slope needed for the roof of the nesting boxes.
7.2 Cover the top and bottom of the nesting boxes with 9/16″ plywood and secure with 2″ wood screws.
7.3 Prepare and install starter course from the pressure-treated lumber with cross section 1/4″ x 3/4″. Prepare the 1/2″ x 6″ wood siding boards in the required amount according to the drawing. Cut the shield’s top part according to the angle of rafter slope. Assemble siding shields with 2″ galvanized nails to the frame beams.
7.4 Prepare wall’s trims from the boards with a cross-section of 3/4″ x 1″; 3/4″ x 2 1/2″; 3/4″ x 3″. Cut the boards at the required angles along the siding contour for the framing.
7.5 Assemble the door frame using 1 1/2″ x 2 1/2″ material according to the illustration and use the same siding material listed in steps 14.3 and 14.4.
7.6 Install four 3″ door hinges using 6×1″ wood screws. Finish the door installation by attaching 4″ surface bolt and 6″ door pull.
7.7 Cover the roof of the nesting boxes with corrugated roof panels and secure with 1 1/2″ sheet metal screws and neoprene washers.
7.8 Install nest box assembles with the help of two corner braces and 8×1″ wood screws. Connect the box frame and coop’s frame by 5″ wood screws.
Step 8 – Install Coop Door
8.1 Assemble the frame from the pressure-treated lumber with cross section 1 1/2 x 3 1/2 ” with 2×5″ wood screws according to the drawing.
8.2 Install door trims from the pressure-treated lumber with cross section 2 1/2 x 3/4″ with 2″ wood screws according to the drawing.
8.3 Prepare and install starter course from the pressure-treated lumber with cross section 1/4 x 3/4 inch.
8.4 Prepare the 1/2 x 6 inch. wood siding boards in the required amount according to the drawing.
8.5 Assemble siding shields with 2″ galvanized nails.
8.6 Install three 6″ door hinges using 2×1″ wood screws. Finish the door installation by attaching 4″ surface bolt and 6″ door pull.
Step 9 – Window Installation
9.1 Use 1 1/2″ x 1 1/2″ pressure-treated material to assemble the frame for the windows. Cut the beams to connect them in the center.

Step 10 – Aviary’s Mesh Wall Installation
10.1 Prepare 1/4″ wire mesh in the required quantity and install it on the inner side of the frames with the help of an industrial stapler.
Step 11 – Installing Corrugated Roofing
11.1 You will need 512 Sq. Ft. of corrugated roofing panels to cover your coop.
