Matched to the animal and the threat, because the wrong fence is worse than no fence.

Fence The Animal You Have

There is no general-purpose livestock fence. Each species defeats fencing differently, and a fence that fails teaches the animal it can be beaten — which is why the wrong fence is genuinely worse than none.

Goats climb, lean and push through. They test every inch of a boundary, daily, for life. Goats need woven wire with small openings, tensioned tight, with a hot wire at nose height on the inside to stop leaning. Horned goats get their heads stuck in anything sized between four and six inches, which is why smaller mesh matters.

Sheep push under. They are less inventive than goats but persistent at the bottom. Keep the lowest wire tight and close to the ground.

Cattle respect a single hot wire once trained and are the easiest to contain, but they lean heavily on anything unelectrified.

Pigs root under everything. Two hot wires low — around six and twelve inches — are more effective than a physical barrier, because a pig's instinct is to go under, not over.

Poultry mostly need protection rather than containment. The fence is there to keep things out.

Electric Fence: What It Actually Does

Electric fence is a psychological barrier, not a physical one. It works because the animal learns the boundary hurts and stops testing it. That has consequences:

Training matters. An animal that meets a hot wire for the first time while panicking will run through it. Introduce new stock to electric fence in a small area, calmly, where they can touch it and back away.

Grounding is where systems fail. A weak fence is almost always a grounding problem, not an energiser problem. Most installations need several ground rods, six to eight feet deep, spaced apart. Dry or sandy soil needs more.

Vegetation drains it. Grass touching the wire bleeds current. Summer growth is why a fence that worked in May stops working in July.

Buy a tester. Guessing at fence voltage by touching it is both unreliable and unpleasant. A fault finder pays for itself the first time it saves you walking a mile of line.

Predator Fencing Is A Different Job

Keeping animals in and keeping predators out are separate problems with different solutions.

Predators dig at the base, so a dig apron of hardware cloth laid flat and extending outward defeats most of them. Climbers need height and often an outward-angled top. Half-inch hardware cloth is the standard for poultry, because a raccoon opens chicken wire by hand.

A hot wire at nose height on the outside is remarkably effective against foxes, raccoons and dogs — animals that investigate with their noses before they climb.

Corners And Gates

Corner and end posts carry the entire tension of a fence line. Undersized, shallow or unbraced corners are the most common structural failure, and no amount of good wire compensates. Set them deep, brace them properly, and expect to spend disproportionate time and money there.

Gates are the weak point in every system. They sag, they get left open, and they are where animals concentrate. Hang them properly and latch them so a person in a hurry still closes them correctly.

Where We Are Honest

Fencing is expensive and boring, and it is also the highest-return infrastructure on a homestead. It works every hour, needs no feeding, and prevents the losses that guardian animals, lights and deterrents only reduce.

The common failure pattern is building cheap fence first and rebuilding properly later, at more total cost. If money is limited, fence a smaller area properly rather than a large area badly.

Common Questions

Is electric fence safe around children and pets?

A properly specified livestock energiser delivers a short, sharp, unpleasant pulse rather than a continuous current. It is designed to be survivable and it genuinely hurts. Signage and sensible siting matter.

Can I electrify existing woven wire?

Yes, with offset insulators holding a hot wire clear of the mesh. Never electrify the woven wire itself.

How tall for goats?

Four feet minimum for most breeds, taller for athletic ones, and with the top made unattractive to lean on.

Solar or mains energiser?

Mains is stronger and more reliable where you can reach it. Solar suits remote paddocks; size it generously, because an underpowered energiser trains animals that the fence can be beaten.
