Why Sheep and Goats Are Harder to Fence Than Cattle
Three things separate sheep/goat fencing from cattle fencing, and ignoring them is the most common cause of a fence that "doesn't work" for small ruminants:
1. Coats insulate. Wool on sheep and hair on goats reduces contact with the conductor — what feels like a 4,000-volt shock to a cow is a 2,000-volt shock to a goat. To get the same training effect, you need to hit them harder. Target 4,000–6,000 volts at the fence under load, vs. 2,500–4,000 for cattle.
2. They go through, not over. Goats jump and climb, sheep crawl through tiny gaps. A single horizontal strand of polybraid won't reliably contain either species. You need a vertical barrier — that's what electric netting provides.
3. Predator pressure is real. Coyotes, foxes, loose dogs, and stray livestock all see lambs and kids as opportunities. Electric netting that contains your animals also deters predators on the way in. A 4,000-volt strike trains predators to avoid the property; a permeable fence trains them to come back.

1. The hero product: electric netting
Electric netting integrates the conductor and posts into one continuous roll. It's the right answer for portable rotational grazing on sheep and goats because it solves the vertical-barrier problem and the predator-deterrent problem in a single product. Set up time per paddock is roughly equivalent to running 3–4 strands of polybraid plus driving step-in posts — and the result contains better.
Recommended:
- EverGraze Sheep & Goat Netting — EverGraze 4ft × 164ft Green Netting ($110). 4-foot tall (right height for sheep and most goats), 164-foot rolls (a quarter of a typical paddock perimeter), with built-in step-in posts. UV-stabilized for years of outdoor use. Stake into ground, connect to energizer, done.
2. Energizer — sized for higher voltage targets
Sheep and goats need 4,000–6,000 volts at the fence under load — higher than cattle because wool and hair reduce contact. That translates to more joules per mile than the equivalent cattle setup, plus extra headroom for the vegetation that always finds its way into a netting paddock.
Recommended for sheep/goats:
- Small flock, 1–2 netting paddocks, off-grid: Speedrite S500 Solar (0.5J, $332). Enough for 1–2 rolls of netting under normal vegetation.
- Small flock, AC available: Speedrite 1000 Dual (1J, $174) — same output as the S500 but plug-in. Best value for AC-equipped sites.
- Mid-size, off-grid, rotational: Speedrite S1000 Solar (1J with battery included, $457) — the workhorse. Handles 3–4 rolls of netting under most conditions.
- Mid-size or predator pressure, AC available: Cyclops CHAMP 5J AC ($268) — best dollar-per-joule in the catalog, plenty of headroom for goat-grade vegetation contact.
- Heavy predator pressure: Cyclops BRUTE 8J AC ($366) — when 4,000V isn't enough and you want to discourage repeat coyote visits.
- Battery-only with weekly swap: Cyclops STALLION 2.5J DC ($245) — compact unit for remote pastures where you can't run AC and don't want a panel.
3. Grounding — even more critical for small ruminants
Because sheep and goats need higher voltage at the fence to feel the shock through coats, the grounding system has to work harder. Same rule as cattle (3 ft of ground rod per joule of energizer output, spaced 10 ft apart in moist soil), but the consequences of bad grounding hit small-ruminant fences first — that's where you see livestock walking through what should be a hot fence.
Recommended:
- Galvanized ground rod — Galvanized Ground Rod 6' x 5/8" ($15). For a 5J energizer, 3× rods driven 10 ft apart.
- Ground rod clamp — Bronze Ground Rod Clamp ($3) for each rod.
4. Lightning protection — non-negotiable for unattended pasture
A direct or near-miss lightning strike fries energizers, and sheep/goat netting paddocks are often on remote pasture where damage isn't noticed for days. By the time you check the fence, predators may have already noticed it's dead. Spend $50 on protection now or $500–$2,000 replacing an energizer later.
Recommended:
- Fence charger lightning diverter — Lightning Diverter ($9) — inline surge protection between the energizer and the fence.
5. Polybraid for cross-fencing inside a netting paddock (optional)
If you're running multi-paddock rotational grazing on sheep/goats, you may want polybraid + step-in posts for the interior subdivisions while the perimeter is netting. Same setup as the cattle kit, but tighter post spacing (10–15 ft instead of 20–30) and lower wire heights.
Recommended:
- Super 9 Polybraid 1,320' — Super 9 Mixed-Metal Polybraid ($79). High-visibility blue/white striped, 300+ lb break strength.
- O'Brien Treadaline step-in posts — white or blue ($5.99 each, box of 50). Run wires at 6", 12", 22", 32" for goats; remove the top wire for sheep-only.
- Taragate 3:1 Geared Reel — Taragate Reel ($90). Same workhorse reel used on cattle setups.
6. Gates
Even with netting, you'll want gate access for moving animals and equipment. Spring gates work for sheep and goats; just keep them under 16 feet so the lower wire stays at lamb-catching height.
- 16-foot spring gate — Spring Gate Kit 16' ($16) — standard paddock width.

Set up the netting on a clean, mowed strip. Vegetation contact with netting reduces conductivity fast — a goat-grade fence will short out where grass touches the bottom strand. Run a mower or weed-eater along the planned fence line before deploying netting. Spend 20 minutes mowing and save weeks of voltage drop.
Train new animals in a small pen first. Same protocol as cattle — small pen with hot netting, let them touch it once or twice, then trust them in larger paddocks. Don't move untrained animals straight into a netting paddock; they'll hit it once, panic, and may tangle.
Check voltage at the far end weekly. Sheep and goat fences fail more silently than cattle fences — animals don't bolt through the gap, they just drift out one at a time. A weekly voltmeter check at the far end of the netting catches the problem before livestock notice.
Watch for kids born inside a netting paddock. Newborn kids and lambs can fit through netting holes that adults can't. Plan kidding/lambing in a separately fenced pen, not in an active netting paddock.
Connect netting rolls electrically. When joining multiple netting rolls, make sure the conductor wires are physically touching at the join — don't just rely on the netting being adjacent. A short jumper lead between rolls keeps voltage consistent across the full perimeter.
