Sheep fence is the first real decision you make as a sheep keeper, and getting it wrong is expensive in every direction. Sheep are not aggressive escapers by nature, but they are persistent grazers, easily spooked, and almost completely defenseless against predators. The fence that contains them and the fence that protects them from predators are two different problems, and a good sheep fence solves both at once.
Key Takeaways
What Makes Sheep Fence Different from Other Livestock Fence
Sheep have specific fencing requirements that differ meaningfully from goats, cattle, and hogs. They do not typically challenge fence the way goats do, but they respond to predator pressure by bunching and pushing, which puts stress on corners and gate posts in ways that weaker fencing systems cannot handle. A sheep that panics is a sheep that will find every weak point in the line.
The other factor is predator vulnerability. Sheep have no meaningful defense against dogs, coyotes, or foxes, and a fence that only contains sheep is not the same as a fence that protects them. Perimeter fence for sheep needs to be designed with both containment and exclusion in mind from the start.
What Height Does a Sheep Fence Need to Be?
A minimum of 48 inches is the working standard for sheep. Most sheep will not attempt to jump a well-maintained four-foot fence, but height alone is not the measure. A fence can be tall and still fail if the spacing at the base allows a lamb to slip through or a fox to push underneath.
For flocks that include rams during breeding season, 52 to 60 inches provides a meaningful safety margin. A ram pushed by instinct or agitation is considerably more motivated than a dry ewe on summer pasture, and a fence that holds the rest of the flock comfortably may not hold him.
What Type of Fencing Works Best for Sheep?
Woven wire, sometimes called field fence or stock fence, is the foundation of a reliable sheep fence. Look for openings no larger than four by four inches, which prevents lambs from getting their heads caught and limits the gaps predators can exploit. Standard 12.5-gauge woven wire at 48 to 52 inches height handles most homestead sheep fencing situations.
The openings on cheaper woven wire products are often graduated, with larger spacing at the top and smaller at the bottom. This works reasonably well for mature sheep but leaves lambs vulnerable at the base. Fixed-knot woven wire with uniform four-by-four openings costs more per roll but holds its shape under pressure and lasts significantly longer.
High-tensile wire is a solid option for large perimeter runs where cost per linear foot matters. It requires more careful tensioning and better corner construction than woven wire, and it is less forgiving of installation errors, but a properly built high-tensile sheep fence will outlast most woven wire systems by years.
Does Sheep Fence Need Electric Wire?
A single strand of electric wire run inside the main perimeter fence is one of the most practical upgrades a sheep operation can make. Positioned six to eight inches off the ground on the inside of woven wire, it teaches sheep not to push against the fence and deters predators that might attempt to dig or press underneath from the outside. Oklahoma State University Extension’s guide to electric fencing for sheep covers wire spacing and energizer selection in detail for producers who want to go deeper on permanent electric systems.
Electric fence alone is not sufficient as primary sheep fencing. Sheep are not as reliably trained to electric as pigs or cattle, and a power outage or fence fault during a predator event leaves the flock unprotected. Use electric as a reinforcement layer, not as a standalone system.
Energizers for sheep fence should be sized to the perimeter, not the flock. A two-joule energizer handles up to 25 miles of fence under good conditions, which is far more than most homestead operations need. For a typical one-to-five-acre paddock system, a 0.5 to one-joule energizer is more than adequate.
How to Build a Sheep Fence That Holds Its Shape
Post spacing and corner construction determine whether a sheep fence lasts five years or 20. Line posts for woven wire should be set no more than 12 feet apart, with eight feet preferred in areas where sheep pressure is consistent. Wood posts sunk two to three feet in the ground will outlast T-posts in any woven wire application because woven wire requires tension, and T-posts cannot anchor tension the way a driven wood post can.
Corner assemblies are where most homestead fences fail. A sheep fence corner needs a minimum of two posts per corner, braced with a horizontal rail and a diagonal tension wire running from the top of the outer post to the base of the inner post. The University of Kentucky Cooperative Extension recommends H-brace assemblies at every corner and gate opening for woven wire livestock fence, and that guidance holds for sheep specifically.
Gates need to be the same height as the perimeter fence. A sheep that can see over a gate will test it, and a lightweight gate that flexes under pressure trains sheep to push harder. Use heavy-gauge farm gates with the same latch style throughout the system so there are no single points of failure from an unfamiliar mechanism.
How to Set Up Rotational Grazing Paddocks for Sheep
Rotational grazing is the most effective way to manage pasture for sheep and dramatically reduces parasite pressure, since most barber pole worm larvae do not survive more than a few weeks on pasture without a host. The internal fencing that divides a property into paddocks does not need to match the security level of the perimeter fence.
Temporary electric netting works well for internal paddock division. A 164-foot roll of Premier 1 PoultryNet or ElectroNet at 42 to 48 inches height is enough to create four to six movable paddocks within a secure perimeter, allowing the flock to rotate on a schedule of seven to 14 days per paddock depending on stocking rate and forage recovery time. The perimeter handles predator exclusion; the interior netting handles grazing management.

What About Predator-Proofing a Sheep Fence?
Predator pressure varies dramatically by region, but every sheep operation should build to a minimum standard regardless of what predators are currently present. A fence adequate for today’s threat level can fail catastrophically when a new predator moves in, and rebuilding fence after a loss is far more expensive than building correctly once.
Coyotes are the most common sheep predator across most of North America. A coyote will test a fence by probing the base rather than attempting to jump it, which is why the six-to-eight-inch interior electric wire matters so much. Dogs, especially domestic dogs from neighboring properties, are statistically more responsible for sheep losses than coyotes in many areas and tend to cause more damage per event because they are less cautious.
For high-pressure areas, adding a strand of electric wire along the outside base of the perimeter fence at ground level creates a deterrent from both directions. A livestock guardian dog working within a good perimeter fence is the most effective predator deterrent a sheep flock can have. Our guide to buying and caring for livestock guardians covers breed selection, bonding with the flock, and how to integrate a guardian dog into an existing operation.
Frequently Asked Questions About Sheep Fence
Can sheep climb or jump a four-foot fence?
Most adult sheep will not attempt to jump a well-built 48-inch fence unless severely panicked. Rams during breeding season and sheep under active predator pursuit are the exceptions. A fence of 52 to 60 inches provides a more reliable margin for mixed or breeding flocks.
How far apart should fence posts be for sheep?
Line posts should be set eight to 12 feet apart for woven wire sheep fence, with eight feet preferred where sheep pressure is consistent. Corner and gate posts need H-brace assemblies with horizontal rails and diagonal tension wire to anchor the system under sustained load.
Is electric fence enough to contain sheep on its own?
No. Sheep are not as reliably conditioned to electric fence as cattle or pigs, and a fence fault during a predator event leaves the flock unprotected. Electric wire works best as a reinforcement layer inside and outside a woven wire perimeter, not as a primary containment system.
What is the best fence for keeping predators away from sheep?
Woven wire at 48 inches with four-by-four-inch maximum openings, combined with a strand of electric wire run six to eight inches off the ground on the inside of the fence, handles most predator threats. High-pressure areas benefit from an additional exterior ground-level strand and a livestock guardian dog working inside the perimeter.
How much does it cost to fence one acre for sheep?
A rough estimate for woven wire with wood posts, corner bracing, and one interior electric strand runs between $1.50 and $3.00 per linear foot depending on materials and labor. One acre of square perimeter is approximately 835 linear feet, putting a basic sheep fence in the $1,250 to $2,500 range before gates.
The fence decision shapes everything that follows on a sheep operation. A well-built perimeter with solid corners, appropriate height, and an electric reinforcement strand sets the conditions for rotational grazing, effective predator management, and a flock that stays where you put it. Get the perimeter right before the animals arrive, and most of the management challenges that plague new sheep keepers simply do not develop.
