Building a chicken wire fence requires marking the perimeter, installing posts 6–10 feet apart, digging a 12-inch trench for predator protection, and securing taut wire with staples or zip ties at top, middle, and bottom.
A flimsy chicken wire fence is an invitation to every raccoon, fox, and neighborhood dog within a mile. The fix isn’t heavier wire—it’s proper installation. The difference between a fence that holds for years and one that collapses in the first wind comes down to six choices: post spacing, burial depth, wire tension, fastener type, corner bracing, and gate construction. Miss any one and you’ll be patching holes by week two. Here’s the exact sequence that keeps predators out and birds in.
Planning the Perimeter
Start with the layout before you dig a single hole. Mark the fence line with spray paint or landscape marking flags, keeping corners as close to 90 degrees as possible. Use a carpenter’s square or the 3-4-5 triangle method—measure 3 feet along one line, 4 feet along the other, and adjust until the diagonal between them is exactly 5 feet. A crooked perimeter creates sagging wire at every corner.
Choosing Your Posts: Wood vs. T-Posts
The post type determines the whole install process. Wooden posts last decades but require digging below the frost line, which varies by region—anywhere from 12 inches in the South to 48 inches in northern states. T-posts drive directly into the ground without digging and work well for temporary or garden fences, but they offer less lateral support for gates and corner tension.
| Post Type | Installation Method | Best Use Case |
|---|---|---|
| Wooden (8 ft) | Dig 1.5–2 ft holes, add 2–3 inches gravel, set post, tamp soil every 6 inches | Permanent chicken runs, gate corners, frost-prone areas |
| T-Post (5’6″–7’6″) | Drive 6–8 inches into ground with post driver | Straight runs, garden fences, budget builds |
| Post spacing (wood) | 6–8 ft apart | Stable runs and garden perimeters |
| Post spacing (T-post) | 6 ft apart | Optimal wire tension without sagging |
| Corner bracing | Diagonal 2×4 brace from top of corner post to base of next post | Prevents wire pulling posts inward under tension |
| Gate posts | One size larger (10 ft wooden posts or heavy-duty T-posts) | Supports gate weight and daily swinging |
Digging the Predator-Proof Trench
Most fence failures happen below ground. Dig a 12-inch-deep trench along the entire fence line before installing the wire. Place framing lumber (2x4s) in the trench and secure them with framing nails to create a rigid base. This trench does two jobs: it anchors the wire bottom so nothing can push under it, and it gives you a straight edge to staple against. For extra protection on sloped ground, bend the bottom 6–8 inches of wire outward in an L-shape against the trench wall—digging animals hit the buried section before they reach the interior.
Unrolling and Tensioning the Wire
Roll the chicken wire along the fence line, aligning the bottom edge snugly into the trench. Start at a corner post: clamp or staple the top corner of the wire, then pull the wire taut before fastening the middle and bottom. A helper pulling from the far end works, but a come-along tensioner attached to the far corner post gives consistent tightness across long runs. Over-pulling crushes the wire diamonds and creates weak spots, so stop when the wire is straight without visible sag—not drum-tight. Fasten at the top, middle, and bottom, then add additional staples or zip ties every 12–18 inches between them. For T-posts, use UV-resistant zip ties instead of staples, wrapping them around the post and wire in a figure-eight pattern for permanent hold.
Do I Need to Bury Chicken Wire to Keep Predators Out?
Yes—and shallow burial is the single most common mistake in chicken wire fencing. Burying the wire at least 6–12 inches underground stops raccoons, foxes, and gophers from digging underneath. The L-shaped outward bend at the bottom trench wall makes it even harder for determined diggers because they encounter the buried wire before they reach the interior wall. For high-risk areas with coyotes or roaming dogs, attach a 12-inch strip of hardware cloth to the bottom of the chicken wire—the smaller mesh size prevents predators from tearing through the larger chicken wire diamonds.

Installing the Gate
A sagging gate turns a solid fence into a weak point. Frame the gate opening with 2x4s, using at least three 3-inch wood screws at each joint driven at an angle for strength. Attach a minimum of four L-brackets to reinforce the corners—eight is better for a gate that sees daily use. Hang the gate with three heavy-duty hinges and install a self-latching mechanism so wind doesn’t swing it open. Measure twice: the gate opening should match the finished gate dimensions exactly, with a 1/2-inch gap on each side for hinge clearance. Cut the chicken wire covering the gate opening with wire snips, leaving a 2-inch overlap to wrap around the gate frame before stapling.
Post-Installation Checklist
A fence that looks tight on day one can loosen after the first rain. Walk the entire perimeter and inspect for three things: sagging wire between posts, gaps at the bottom where the trench may have settled, and loose fasteners on corner posts where tension concentrates. Reinforce any loose section with an additional staple or zip tie immediately—waiting a week makes the problem worse. For longer fences, consider a tension wire along the top and bottom of the fence line; run a length of 12-gauge galvanized wire through the mesh at both levels and secure it to end posts with turnbuckles for yearly re-tightening.
FAQs
What gauge chicken wire is best for keeping raccoons out?
Use 20-gauge or thicker chicken wire with 1-inch hexagonal mesh. Standard 22-gauge wire is strong enough for chickens inside the run but can be pulled apart by determined raccoons, especially at seams and corners.
Can I install a chicken wire fence on uneven ground?
Yes. On sloped ground, level the top of each post using a laser or flat line, then run a guide wire at the top of the fence line before attaching the chicken wire. The bottom of the wire can follow the ground contour and adjust the trench depth accordingly.
How deep should the trench be for chicken wire?
Dig the trench at least 12 inches deep around the entire fence perimeter. This depth prevents burrowing predators like foxes and gophers from squeezing under the fence. In sandy soil, go deeper—up to 18 inches—because loose soil makes digging easier.
Should I use staples or zip ties for attaching chicken wire?
Use 3/4-inch poultry staples for wooden posts and UV-resistant zip ties for metal T-posts. Never hammer staples into metal posts—the wire will slip. Zip ties should be wrapped in a figure-eight pattern around the post and wire for permanent stability.
How far apart should fence posts be for chicken wire?
Space wooden posts 6 to 8 feet apart for garden fences and 6 feet apart for chicken runs. T-posts should be placed no more than 6 feet apart for optimal support. Spacing posts wider than 10 feet causes the wire to sag and weakens the entire fence structure.
