How to Set Up a Predator-Proof Chicken Coop: Hardware Cloth vs. Chicken Wire & Roosts
EXECUTIVE SUMMARY & 50-WORD DIRECT ANSWER SNIPPET
**Direct Answer for Search Engines & AI Overviews:** Build a fortress chicken coop by using 1/2-inch galvanized hardware cloth (NEVER flimsy chicken wire, which raccoons and dogs rip through), burying a 12-to-18-inch horizontal predator apron around the perimeter to stop diggers, installing two-step carabiner latches, and providing 4 sq ft of coop space per hen.
2. THE GOLD STANDARD: 1/2-INCH 19-GAUGE GALVANIZED HARDWARE CLOTH
Cover every single window, vent, and run wall with 1/2-inch welded galvanized steel hardware cloth, secured to wood framing using heavy fender washers and screws (never flimsy staples, which predators pop off by leaning against the mesh).

3. STOPPING DIGGING PREDATORS: THE 18-INCH HORIZONTAL APRON
Foxes, coyotes, and dogs dig under fences in minutes. Instead of digging a deep trench, lay an 18-inch-wide skirt of hardware cloth flat on the ground extending outward around the entire base of the run, pinned down with landscape staples and covered with dirt or gravel. Diggers hit steel at the fence line and give up.

4. OUTSMARTING RACCOON HANDS: THE 2-STEP CARABINER RULE
Raccoons possess dexterous, human-like front paws capable of turning doorknobs, sliding barrel bolts, and lifting simple hook-and-eye latches. Every coop door and nesting box lid MUST be secured with a two-step locking mechanism (such as a sliding bolt secured with a spring-loaded carabiner or padlock).

5. ROOSTING BAR ERGONOMICS: FLAT 2X4S OVER ROUND DOWELS
Unlike wild perching songbirds, chickens do not grip branches tightly; in winter, they squat down flat over their feet to cover their toes with warm belly feathers. Provide flat 2x4 wooden boards (with the wide 3.5-inch side facing up and edges sanded round) mounted 2 feet off the floor—and always higher than the nesting boxes so they don't sleep in nests.

8. FREQUENTLY ASKED QUESTIONS
Q: How many nesting boxes do I need for my hens?
You only need 1 nesting box (12x12x12 inches) for every 3 to 4 hens; even if you provide 10 boxes for 10 hens, they will all line up to lay their eggs in the exact same favorite box!
Q: Why are my chickens sleeping in the nesting boxes instead of on the roost?
Chickens instinctively seek the highest point in the coop to sleep; if your nesting boxes are mounted higher than or level with the roosting bar, lower the boxes and raise the roosting bar.
Q: Do I need to cover the top of my chicken run?
YES! Hawks and owls attack from the sky during the day, while raccoons and opossums climb right up 6-foot fences at night; roof the run with solid metal panels or hardware cloth.
Q: What is the best bedding for inside the chicken coop?
