Description
This 40×20 chicken coop plan provides complete blueprints for an 800 square foot setup housing up to 50 chickens, consisting of an elevated 12×9 foot hen house with an attached 28×20 foot fully-enclosed run. The design gives each bird 16 square feet of space, well above minimum requirements, which translates to healthier chickens and better egg production compared to cramped setups.
The elevated hen house features a gable roof with shingles, horizontal wood siding, and sits on posts to prevent flooding and rot. You enter through a full-sized door with steps, meaning no crawling or hunching during daily tasks. Twenty external nesting boxes accessible from outside via hinged lids allow egg collection without disturbing the flock, while a window above provides natural light to encourage laying. The fully-enclosed run with wooden frame and complete wire mesh coverage including the top protects against all predators while giving birds outdoor access for natural behaviors.
The walk-in design throughout both house and run is the key practical advantage, allowing comfortable daily management, easy cleaning with wheelbarrow access, and proper flock health monitoring. With good management, 50 layers can produce 200-300 eggs weekly during peak seasons, enough for small-scale selling or large family operations. The instant PDF download includes email support for questions, and verified customer reviews consistently praise the detailed materials list and clear instructions while noting some elements may be over-engineered for moderate climates.
The structure requires permanent installation with proper site preparation and likely permits for something this size. However, the investment delivers a legitimate small-scale poultry operation setup with professional-level predator protection, weather resistance rated to -25°F with optional insulation, and adequate space to maintain healthy, productive birds long-term.

Based on our product data, most coops require standard woodworking tools:
• Basic tools: Circular saw, drill, measuring tape, level, square
• Materials: Primarily wood construction with options for plywood, OSB, polycarbonate, and asphalt shingles for roofing
• Hardware: Screws, hinges, latches, and hardware cloth for predator protection
Our plans come in three difficulty levels:
• Easy: Perfect for beginners with basic DIY experience
• Medium: Suitable for those with some woodworking experience
• Advanced: Designed for experienced builders
Each plan clearly states the difficulty level and required skills.
We recommend pressure-treated lumber for the frame and any ground contact points, with exterior-grade plywood or OSB for walls and floors. Cedar is an excellent premium option for better weather resistance. All our plans specify appropriate wood types for each component.
Our coop designs incorporate the essential 1:10 ratio of ventilation to floor space through:
• Adjustable vents near the roof
• Cross-ventilation windows
• Gap between walls and roof (protected from rain)
• Covered openings to prevent drafts while maintaining airflow
Our plans feature several cleaning-friendly design elements:
• Full-height or partly access doors for easy interior access
• Removable dropping boards under roosts
• Smooth interior surfaces
• Tilt-out nesting boxes for easy egg collection
• Raised floor design to prevent moisture buildup
Regular maintenance is key for coop longevity:
• Weekly: Clean dropping boards and refresh bedding
• Monthly: Deep clean, check hardware and latches
• Seasonally: Inspect roof, ventilation, and predator proofing
• Annually: Treat wood surfaces and check structural integrity
