What Is Hardware Cloth?
Hardware cloth is a welded wire mesh made from galvanized steel wire, available in various gauges and mesh sizes. The most common size for poultry applications is half-inch mesh in 19-gauge wire. It is rigid, strong, and resistant to cutting, tearing, and prying.
Despite its name, hardware cloth is not cloth — it is a welded metal mesh that holds its shape when cut and attached. The rigid structure makes it effective as a structural panel for coop walls, run enclosures, window covers, and ventilation openings.
Half-inch mesh is the standard for chicken coop and run construction because no common predator — including weasels, rats, raccoons, or snakes — can fit through a half-inch opening. Quarter-inch mesh provides even better protection against small snakes and mice but is more expensive and harder to work with.
What Is Chicken Wire?
Chicken wire (also called poultry netting or hex wire) is a lightweight woven wire mesh with hexagonal openings, typically one inch or two inches across. It is made from thin-gauge galvanized wire that is flexible, easy to cut, and inexpensive.
Chicken wire was designed to contain chickens — to keep them in a designated area. It was never designed to keep predators out. The thin wire and large openings provide almost no barrier against determined predators. Raccoons tear through chicken wire with their hands. Dogs bite through it. Even rats can squeeze through two-inch openings.
The name "chicken wire" is unfortunately misleading. New keepers assume it is the appropriate material for chicken enclosures, when in fact it is the one material that should not be used for predator protection.
Predator Resistance Comparison
This is not a close comparison. Hardware cloth provides genuine predator protection. Chicken wire provides almost none.
Raccoons — the most common predator for backyard coops — can reach through one-inch chicken wire mesh, grab a sleeping chicken, and pull it through the wire piece by piece. This is not hypothetical; it is one of the most common predator attacks reported by backyard keepers. Hardware cloth's half-inch mesh prevents raccoon hands from reaching through.
Weasels and minks, which kill entire flocks in a single night, fit through one-inch openings easily. Half-inch hardware cloth stops them.
Dogs and coyotes can bite through, push through, or tear chicken wire from stapled frames. Hardware cloth, attached with screws and washers, resists these attacks.
The only animals that chicken wire effectively stops are the chickens themselves — which is what it was designed to do.
Snake protection is another area where hardware cloth provides clear superiority. Snakes — especially rat snakes and king snakes — enter coops through openings as small as one inch to eat eggs and chicks. Half-inch hardware cloth stops all but the smallest snakes. Two-inch chicken wire allows all but the largest snakes to pass through freely.
Rat exclusion follows the same pattern. Rats squeeze through openings slightly larger than half an inch — easily cleared by chicken wire's large hexagonal mesh. Hardware cloth's half-inch grid stops rats from entering the coop, where they eat feed, chew wiring, and can attack chicks and eggs. Rat prevention is a biosecurity issue as well as a predator issue — rats carry diseases that affect poultry.
Cost, Installation, and When to Use Each
Hardware cloth costs significantly more than chicken wire — roughly three to five times as much per linear foot, depending on gauge and mesh size. It is also harder to cut (tin snips or wire cutters required), heavier to handle, and must be attached with screws and fender washers rather than simple staples for secure installation.
Chicken wire is cheap, lightweight, and easy to install with a staple gun. It cuts easily with standard scissors or wire cutters and conforms to curved surfaces readily.
Use hardware cloth for all predator-facing applications: coop windows, ventilation openings, run walls, run tops, and ground aprons. Use chicken wire only for temporary garden fencing to keep chickens out of planting beds, or as a lightweight barrier inside a fully enclosed structure where predator protection is provided by an outer layer of hardware cloth or solid walls.
The cost difference is real, but a single predator attack that kills your flock costs far more than the hardware cloth that would have prevented it. Budget for hardware cloth from the start.
For maximum protection at minimum cost, many keepers use hardware cloth on the lower three to four feet of run walls (where predator contact occurs) and bird netting on the top section and overhead (where hawks are the primary threat). This tiered approach provides hardware-cloth-level ground defense and hawk deterrence at a lower total cost than full hardware cloth enclosure.
Attachment method matters as much as material choice. Hardware cloth attached with a staple gun alone is not secure — raccoons can pull stapled mesh off wooden frames with sustained effort. Use galvanized screws with fender washers every four to six inches for a raccoon-proof attachment. The washers spread the holding force across a larger area of the mesh, preventing pullout.
Galvanization quality affects long-term durability. After-galvanized hardware cloth (welded first, then galvanized) is more corrosion-resistant than galvanized-before-welding (where the weld joints lack galvanization and rust first). Look for hardware cloth labeled "after galvanized" or "hot-dipped galvanized" for the longest outdoor lifespan. In coastal salt-air environments or very wet climates, stainless steel hardware cloth is available at a premium price and lasts indefinitely.

Frequently Asked Questions
Can raccoons get through hardware cloth?
No. Half-inch hardware cloth prevents raccoons from reaching through the mesh. They cannot tear or pry apart welded 19-gauge wire. Attach hardware cloth with screws and fender washers — not just staples — for maximum security.
Is chicken wire ever appropriate for a chicken coop?
Only in situations where predator protection is not a concern — for example, as a lightweight garden fence to keep chickens out of flower beds, or as an inner divider inside a fully predator-proofed structure. Never use chicken wire as the sole barrier between your flock and the outdoors.
What gauge hardware cloth should I use?
19-gauge with half-inch mesh is the standard for poultry applications. Heavier gauges (lower numbers, like 16-gauge) are stronger but more expensive and harder to work with. 19-gauge is adequate for all common backyard predators.
