Chicken Coop Hardware Cloth: The Right Way to Use It
Chicken wire keeps chickens in. It does not keep predators out. Raccoons reach straight through it, weasels slip through anything wider than an inch, and a determined dog tears it off the frame. The material that actually protects a coop is hardware cloth, and how you mount it matters as much as what you buy.
What to buy
Mesh size: half inch. Quarter inch is even more secure but harder to work with; one inch lets weasels and young rats through. Half-inch galvanized mesh is the standard for coop protection.
Gauge: 19 or heavier. Thinner mesh cuts easily and sags over time. Galvanized after welding resists rust years longer than cheap pre-galvanized rolls.
Where it goes
Every opening a predator could use: windows, vents, gaps under the roofline, the run walls, and if you have digging predators, an apron laid flat around the perimeter. Do not forget the small triangular gaps where roof meets wall; weasels use exactly those.
How to mount it so it holds
Staples alone fail: a raccoon works a corner loose in one night. Use screws with fender washers every 6 to 8 inches, sandwiching the mesh against the frame. Overlap sheets by at least 2 inches and screw through both layers. Where mesh meets the ground, either bury it 12 inches or bend it outward into an apron.
The one gap hardware cloth cannot close
The pop-hole. Your birds walk through it every day, so it cannot be meshed. It has to be closed reliably every night, which is a routine job humans are bad at and timers are good at.
That last gap is what our automatic coop door with timer closes, on schedule, every evening.
