Choose 1/2-inch, 19-gauge galvanized hardware cloth for your chicken coop to block most predators, or 1/4-inch mesh where snakes and rodents are a concern.
Picking the right hardware cloth comes down to one question: which predators are you keeping out? The answer shapes the mesh size, the wire gauge, and how you bury the bottom edge.
Mesh Size and Gauge: What the Numbers Mean
Hardware cloth is welded steel wire, usually galvanized, sold in rolls with square openings. Mesh size is the opening between wires; gauge is the wire thickness. Lower gauge numbers mean thicker, stronger wire. For most coops, the standard is 1/2-inch mesh in 19-gauge—small enough to block raccoons, foxes, and cats while resisting pulling and tearing. Flockline and other sources treat this as the default for walls and runs. Where snakes, mice, rats, or very small weasels are known problems, step down to 1/4-inch mesh to keep out creatures that slip through a half-inch gap; the trade-off is higher price and heavier rolls.
Where the Mesh Goes: Walls, Vents, and Runs
Use hardware cloth on coop walls, windows, vents, and lower run panels where predators test edges. A common mistake is wrapping the coop but leaving a vent open or a gap under the door.
- Coop walls and windows: attach over every opening, overlapping seams by at least an inch.
- Vents near the roof line: cover fully to block climbing raccoons.
- Lower run sections: use the heaviest mesh here, where predators push and dig.
- The top of the run: cover if hawks or owls are active.
Digging Predators and the Buried Apron
Wire on walls means nothing if a fox digs underneath. Two approaches work together: bury the cloth at the base, or lay a flat apron outward on the ground. The Garden Coop recommends a buried barrier at least 12 inches deep with an apron extending 12 inches outward for foxes; in higher-pressure areas, some sources push that apron to 18–24 inches. Fastening matters too: staples alone pull loose when a raccoon grabs the mesh. Screws with washers, spaced every few inches, hold cloth flat and tight against the frame. Pair this with secure latches on every door—hardware cloth keeps predators out, but a latch seals the coop.
Common Mistakes to Avoid
- Using chicken wire instead of hardware cloth—it does next to nothing against a determined raccoon.
- Choosing 1-inch mesh where weasels or snakes are active; they slip through.
- Leaving vents, windows, and lower edges unprotected—every gap is an invitation.
- Skipping dig protection at the base of the coop or run.
- Relying on staples alone to hold the wire; predators can peel it back.
- Leaving the run top open where hawks hunt.
What Hardware Cloth Costs and Where to Get It
Prices vary by seller, mesh size, roll length, and gauge. A 25-foot roll of 1/2-inch hardware cloth typically runs $20–$45, while finer 1/4-inch mesh lands between $30 and $60. YARDGARD, Amagabeli, and LAN JIA are common brands at farm and hardware retailers; compare per-foot cost, not just roll price, when deciding between 25-foot and 50-foot options.
| Mesh Size | Gauge | Best For |
|---|---|---|
| 1/2-inch | 19-gauge | Standard protection against raccoons, foxes, and cats |
| 1/4-inch | 19-gauge | Excluding snakes, mice, rats, and small weasels |
| 1/2-inch | 23-gauge | Lighter use where predators are not the main worry |

The core picks stay the same: 1/2-inch, 19-gauge galvanized wire for general predator protection, and 1/4-inch mesh for small pests. Screw edges down tight, bury the bottom or lay an apron outward, and cover every opening—that combination keeps your flock safe.
FAQs
Can I use chicken wire instead of hardware cloth?
Chicken wire is fine for keeping chickens in a run, but it is not adequate predator protection. Raccoons and foxes can tear through thin, loosely woven wire within minutes.
How deep should I bury hardware cloth around the coop?
Bury cloth at least 12 inches deep, with an apron extending 12 inches outward, to block digging predators. In heavier-pressure areas, some sources recommend an 18–24 inch outward apron.
Does galvanized hardware cloth rust?
Galvanized hardware cloth resists rust far better than uncoated steel, but it is not rust-proof. Over time, moisture and soil contact can corrode the coating, especially where wire is cut or bent. Some sources prefer wire galvanized after welding, since cut edges stay protected. Inspect the coop base yearly and replace corroded sections.
