Sheep Fencing: How to Choose the Right Setup in 2026

Losing an animal overnight is every shepherd's worst fear, and the numbers explain why. In 2019, roughly 607,000 sheep and lambs died in the US, a loss valued at about $121.6 million. Good fencing is your first and cheapest line of defense, which is exactly why picking the right barrier matters so much. If you also run goats, our guide to electric fencing for sheep and goats pairs nicely with everything here.

Choosing the right sheep fencing isn't about buying the most expensive wire. It's about matching the fence to your land, your flock, and your predators. According to USDA data reported by Morning Ag Clips, operators spent around $51.4 million on nonlethal predator management methods, and fencing sits right at the heart of that spending.

What your fence actually has to do

Before you compare materials, get clear on the job. A sheep fence has two roles: keep your flock in, and keep predators out. Most farms need two kinds. Perimeter fencing runs the boundary and takes the predator pressure. Interior or cross fences simply split pastures into paddocks for rotational grazing.

Fencing is the tool producers reach for most. Among US sheep operations, fencing ranked as the top nonlethal method in 2019, used by 48.3 percent of operators, ahead of night penning and lamb sheds. That popularity isn't an accident. A solid fence works around the clock without feeding, training, or a paycheck.

Woven wire: the traditional workhorse

Woven wire is the classic choice, and for good reason. It's built from horizontal smooth wires held apart by vertical "stay" wires, creating a mesh that acts as a genuine physical barrier. A four-foot fence with tight mesh spacing stops lambs from slipping through and keeps most predators from pushing in.

The trade-off is cost and weight. Woven wire is one of the pricier options to install, and standard grades can sag over time. Many shepherds add a barbed or electric offset wire along the top and a "rust" wire near the ground to extend its life. If you keep both species, the mesh logic is nearly identical, and our woven wire goat fencing guide breaks down knot types and spacing in detail.

High-tensile electric: strong, affordable, low-maintenance

If you're fencing a large area on a budget, multi-strand high-tensile electric fencing is hard to beat. Cattle might respect one or two hot wires, but sheep need more. Five to seven strands of 12.5-gauge wire is typical, with the bottom wires spaced closer together to block predators from crawling under.

Here's the key mindset shift: an electric fence is a psychological barrier, not a physical wall. Sheep have to be trained to respect it, but once they are, they'll stay put even if the power blips. The economics are compelling too. Wildlife Services analysis cited by USDA APHIS found that every dollar spent on predation management saved about three dollars in livestock. Just remember that poor grounding causes most electric fence failures, so install at least three ground rods per energizer.

Temporary and portable options

Not every fence needs to last twenty years. For rotational grazing or grazing a harvested field, temporary electric netting and polywire shine. Netting combines a mesh look with an electric punch in a lightweight, portable format that you can move in minutes.

Polywire and polytape are the cheapest movable options. Polytape is more visible, which helps sheep learn the fence faster, while polywire costs less and lasts longer. Pair either with step-in posts and a reel, and you've got a flexible grazing system. These setups won't match a woven wire perimeter for predator defense, so treat them as interior tools, not your outer wall.

What predators really cost, and why fencing pays

The case for investing in good fencing gets stronger when you look at recent state-level numbers. In Colorado, predators caused about $4.35 million in losses in 2023, accounting for roughly half of all sheep and lamb deaths in the state. Coyotes remained the top threat, followed by dogs and mountain lions.

That's the real math behind fence selection. A fence that keeps coyotes out isn't an expense; it's insurance against your single biggest controllable loss. Bottom wires spaced close to the ground, offset electric wires at nose height, and a solid perimeter all target the ways predators actually breach a fence: under it, through it, or around it.

Posts, slopes, and getting the setup right

Even the best wire fails on a bad frame. Corner and gate posts do the heavy lifting, so they should be the strongest posts on your farm. Treated wood suits permanent boundaries, while steel T-posts or fiberglass work well for line and temporary runs. One perk of high-tensile wire is that it needs fewer posts, which trims your material bill.

Uneven ground adds a challenge, since gaps at the bottom of a slope invite predators and escapees. Our guide to building a fence on a slope walks through the tricks that keep your line tight over hills and dips. And once the flock is secure, the daily grind of grooming, hoof trimming, and feeding is where the right gear pays off, so it's worth browsing our sheep care equipment to round out your setup.

Bringing it all together

The right fence is the one that matches your land and beats your predators, not the flashiest one on the shelf. Given that US producers lost roughly $121.6 million in sheep and lambs in 2019, a woven wire or multi-strand high-tensile electric perimeter is money well spent, backed up by portable netting for smart rotational grazing. Get your grounding, spacing, and corner posts right, and you're most of the way there. Once the flock is safely contained, the equipment we design and test in real farm conditions makes the daily care routine dramatically easier and safer.

Frequently Asked Questions

How tall should a sheep fence be?

Aim for at least 48 inches for a perimeter fence. That height keeps most sheep in and helps deter climbing predators. Add offset or top wires for extra security in high-pressure areas.

Is electric fencing safe for sheep?

Yes, when installed correctly. A properly grounded 4,000-volt charger delivers a memorable but harmless shock. Sheep quickly learn to respect it, and it works well alongside our care equipment once they're trained to the fence.

Should I use barbed wire for sheep?

It's generally not recommended. Sheep can snag their wool and get injured, and barbed wire doesn't reliably stop predators. Use woven wire or electric fencing as your main barrier instead.
