Introduction
Raising backyard chickens provides fresh eggs, pest control, and companionship. Building an affordable DIY chicken coop saves money and allows customization. Follow these budget-friendly steps using accessible materials and simple tools.

1. Planning & Design Considerations

• Determine Flock Size: Allocate at least 4 sq ft of indoor space per chicken; for 4–6 hens, plan a coop measuring 8×8 feet.

• Local Regulations: Check city ordinances and HOA rules regarding coop size, placement, and noise restrictions.

• Predator Protection: Use sturdy materials and ½-inch hardware cloth (not chicken wire) to deter raccoons, raccoons, foxes, and dogs.

2. Materials & Tools List

• Primary Materials:

  • Pressure-treated 2×4 lumber for framing

  • ½-inch plywood sheets for siding and roof decking

  • Corrugated metal panels or asphalt shingles for roofing

  • ½-inch hardware cloth for run enclosure and ventilation

  • Concrete blocks or gravel for foundation to prevent rot and burrowing predators

• Fasteners & Hardware: Galvanized screws, nails, hinges, latches, metal brackets, and weatherproof sealant

• Tools: Circular saw, drill, hammer, tape measure, level, speed square, and staple gun

3. Foundation & Flooring
Step 1: Site Selection & Preparation

• Choose a level, well-drained area with morning sun and afternoon shade.

• Clear debris and mark coop corners using stakes and string.

Step 2: Foundation Installation

• Place concrete blocks at each corner and midpoints to raise the coop off the ground, preventing rot and deterring burrowing.

• Spread a gravel base between blocks to promote drainage.

Step 3: Floor Framing

• Construct a floor frame using pressure-treated 2×4 joists spaced 16 inches on center. Secure to blocks with metal brackets.

• Attach ½-inch plywood flooring to joists; seal edges with exterior caulk to prevent moisture infiltration.

4. Framing Walls & Roof
Step 1: Wall Frames

• Cut 2×4 studs to desired wall height (e.g., 6 feet front, 5 feet back for sloped roof).

• Assemble front, back, and side wall frames with openings for doors and windows.

• Erect frames and secure to floor using angle brackets; check for level and square alignment.

Step 2: Roof Rafters & Sheathing

• Install rafters (2×4) spanning front to back with at least a 12-inch overhang for weather protection.

• Attach ½-inch plywood sheathing to rafters; seal seams with waterproof tape.

Step 3: Roofing Material

• Secure corrugated metal panels or asphalt shingles to sheathing, ensuring proper overlap to prevent leaks.

5. Siding & Ventilation

• Siding Installation: Attach ½-inch plywood siding to exterior wall frames; seal seams with exterior-grade caulk.

• Ventilation: Cut vent openings near the ridge on both sides; cover with hardware cloth to allow airflow while keeping predators out.

6. Nesting Boxes & Roosts

• Nesting Box Construction: Build 12×12×12-inch boxes attached to the coop’s exterior with hinged tops for easy egg collection.

• Roosting Bars: Install 2×4 or wooden dowel roosts 12 inches off the floor and 18 inches apart; place roosts higher than nesting boxes to encourage nighttime use.

7. Chicken Run & Security

• Run Frame: Erect posts sunk 6–8 inches into the ground at corners and midpoints to secure hardware cloth against digging predators.

• Hardware Cloth Enclosure: Attach ½-inch mesh around run frame, burying a 6–8-inch skirt underground.

• Access Door: Build a hinged door with a secure latch; reinforce edges with metal flashing to prevent pecking or scratching.

8. Finishing Touches

• Paint & Seal: Apply non-toxic, exterior-grade paint or stain to protect wood. Avoid lead-based products.

• Install Accessories: Add feeders, waterers, and grit stations. Position feeders off the ground to reduce contamination.

• Predator-Proofing: Use locks and carabiners on doors and nest box lids; consider a motion-activated light or sensor for added security.

9. Budget-Saving Tips

• Reclaimed Materials: Source reclaimed lumber from construction sites or Habitat for Humanity ReStores for discount pricing.

• DIY Hardware Cloth Frames: Build wooden frames to hold hardware cloth securely, saving on pre-fabricated panels.

• Community Giveaways: Check local classifieds, community boards, and neighbors for leftover building materials.

Conclusion
Building a budget-friendly DIY outdoor chicken coop involves careful planning, sturdy materials, and thoughtful predator-proofing. By selecting the right site, creating a solid foundation, and using reclaimed materials where possible, you’ll create a safe, comfortable home for your flock. Regular maintenance and routine inspections ensure longevity and a happy, healthy coop.
