Goat‑Proof Fence: How I Stopped My Herd From Burrowing Through the First Barrier

It was 5 a.m., frost still clinging to the grass, the smell of damp earth and burnt wood in the air. I heard a clang from the north side of the pasture – a post had snapped. Two goats were already nibbling the broken wire, a third was already testing the gap. My cattle fence had held for years, but the goats had found the weak spot.

My First Goat‑Break Fence

The fence was a simple 4‑rail cattle fence. I’d used 4‑by‑4 posts set 8 feet apart, barbed wire on the top, plain wire in the middle. It cost $120 and a day of labor. I thought the barbed wire would be enough to keep the goats out. I was wrong.

The first night, one goat nudged a lower wire with its nose. The wire bent, the goat slipped through, and the next morning the whole herd was on the other side, chewing the corn patch.

My heart pounded. I stared at the broken wire, the bent post, the dirt scuffed away. The goats made a habit of testing any opening. I realized I was building a fence for cattle, not for goats.

Design Principles for Goat‑Proof Fencing

Goats are climbers, jumpers, and diggers. They can squeeze through a 4‑inch gap and push down a loosely set post. The fence must address three things:

• Height – 5 feet minimum. Goats can jump 4‑5 feet if motivated.
• Mesh size – no larger than 2 inches. Anything bigger becomes a foothold.
• Post stability – set deep enough and brace against outward pressure.

Materials matter too. Woven wire (often called “field fence”) works better than single strand. Adding a top rail of 2‑inch hardware cloth prevents them from climbing up and over.

Building the Fence

I started at the broken section. First, I removed all the old wire. Then I dug new post holes, 2 feet deep, using a post‑hole digger. I added 12 inches of gravel at the bottom for drainage, then set the post, filled the hole with soil, and tamped it down with a piece of timber.

Next, I attached a 5‑foot high woven wire roll. I stretched it tight with a come‑along, anchored it to the first post with a strong tie‑wire, then secured it to each subsequent post. I left a 2‑inch overlap at each joint and twisted the wires together. The overlap prevents goats from slipping the wire apart.

At the top, I ran a 2‑inch hardware cloth strip for 10 feet on each end, where goats tend to try climbing. I stapled it to the woven wire and nailed it to the posts.

Finally, I installed a gate. I used a heavy‑duty steel gate with a latch that can’t be pried open with a goat’s head. I set the latch about 3 inches off the ground, high enough that a goat can’t reach it, but low enough for me to pull.

All told, the fence took two solid days and about $250 of material. The cost was higher than my cattle fence, but the peace of mind was worth every penny.

What I’d do differently

If I could start over, I’d:

• Lay the posts 10 feet apart instead of 8 feet. Fewer posts mean fewer weak spots.
• Use 3‑inch mesh woven wire for the main panel. The extra strength stops goats from pushing the wire inward.
• Set the post holes 3 feet deep on the hill side of the pasture. The extra depth counters the outward pressure from goats leaning on the fence.
• Install a 4‑inch high “goat‑guard” rail on the inside of the fence, a few inches above the ground. It stops them from digging under.
• Put a metal “cattle guard” at the gate entry. Goats try to push the latch open; the guard prevents that.

Checklist for This Week

Take a few hours, walk the perimeter, and fix the weak points.

1. Inspect every post. If any wiggle, re‑dig and set deeper.
2. Check the mesh size. Anywhere you see a gap larger than 2 inches, replace that section.
3. Pull the top wire taut with a come‑along. A loose wire is a goat’s invitation.
4. Test the gate latch. Hang a 5‑pound weight on it; if it bends, replace the latch.
5. Lay down a 4‑inch strip of hardware cloth along the bottom for any area where goats have already dug.
6. Mark the fence line with a spray paint line. It helps you see gaps you might miss.
7. Log any damage you find. A simple notebook entry helps you spot patterns.

After a week of tightening, the goats stayed where they belong. The fence holds. The lesson sticks: don’t assume a cattle fence will stop a goat. Build for the animal you have, not for the one you used to have.
