The Complete Guide to Electric Fencing for Poultry and Livestock

How Electric Fencing Works

An electric fence does not physically restrain an animal. It delivers a brief, sharp, harmless electric pulse when an animal (or predator) touches the live wire while in contact with the ground. The pulse travels from the energiser, through the fence wire, through the animal's body, through the ground, and back to the energiser via the grounding rod — completing an electrical circuit.

The shock is unpleasant but not dangerous. It is a psychological deterrent — the animal learns that touching the fence produces an immediate, memorable consequence and avoids it thereafter. A fox that receives a shock from poultry netting will typically leave and not return.

The system has three components: the energiser (generates the pulse), the fence conductor (carries the pulse — in poultry netting, this is the horizontal wires woven into the mesh), and the grounding system (the earth rod that completes the circuit).

All three must function correctly for the fence to work. A fence with a perfect energiser and perfect conductor but poor grounding delivers no shock. Grounding is the most commonly failed element.

Electric Poultry Netting — The Standard for Small Flocks

Electric poultry netting is a pre-assembled mesh fence — a roll of horizontal conductive wires (typically ten or eleven, most or all electrified) connected by vertical non-conductive struts, supported by built-in plastic posts with twin-spike ground stakes. It unrolls from the package into a ready-to-use fence line.

Standard dimensions. Netting is typically 120 cm (48 inches) tall and comes in rolls of 25 metres (82 feet) or 50 metres (164 feet). The 120 cm height is sufficient to contain most chicken breeds, though particularly flighty breeds may clear it. The close mesh spacing at the bottom of the netting (approximately 6–8 cm / 2.5–3 inches) prevents small chicks from escaping.

The bottom wire is typically not electrified on most netting designs. This prevents the fence from grounding out through grass and soil contact. The lowest electrified wire sits a few centimetres above ground level.

How it contains poultry. The netting acts as both a physical mesh barrier (chickens cannot walk through it) and a psychological electrical deterrent (anything that touches the electrified wires receives a shock). For the poultry themselves, the physical barrier is usually sufficient — most chickens respect a mesh fence. The electrical element is primarily for predator deterrence.

Energisers — Mains, Battery, and Solar

The energiser generates the pulsed electrical output that makes the fence effective. The output is measured in joules — the energy delivered per pulse. For poultry netting, a minimum output of 0.25 joules is needed, though 0.5–1.0 joules is recommended for reliable performance, particularly if vegetation contact is likely.

Mains-powered energisers plug into a standard electrical socket. They provide consistent, reliable output with no battery management. They are the best choice when the fence is within reach of a power supply (via insulated electric fence wire — not a domestic extension lead, which is unsafe outdoors). Mains energisers are the most powerful and the most reliable option.

Battery-powered energisers use a rechargeable 12-volt battery (similar to a car battery or leisure battery). They are portable and suitable for locations without mains access. The battery requires periodic recharging — how often depends on the energiser's draw and the battery capacity. Some models accept multiple power sources (battery and mains), providing flexibility.

Solar-powered energisers combine a solar panel with a rechargeable battery. The solar panel charges the battery during daylight, and the battery powers the fence continuously. Solar energisers are ideal for remote locations without mains power and without the inconvenience of battery swapping.

Solar limitations. Performance depends on sunlight. During prolonged overcast weather or short winter days, the battery may not fully recharge, leading to reduced fence voltage. Position the solar panel in the sunniest available location. In regions with limited winter sun, a solar energiser may not provide year-round reliability — consider mains or a mains/battery hybrid for winter months.

Grounding — The Element Most People Get Wrong

The grounding rod is the most overlooked and most frequently failed component of an electric fence system. Without proper grounding, the circuit cannot complete, and the fence delivers no shock — even if the energiser is working perfectly.

How grounding works. The earth rod (a metal stake driven into the ground) is connected to the energiser's ground terminal. When an animal touches the live fence wire while standing on the ground, the electrical pulse flows through the animal's body into the ground, through the soil to the earth rod, and back to the energiser. If the earth rod is poorly installed — too shallow, in dry soil, in rocky ground — the resistance is too high and the shock is weak or absent.

Best practice. Drive the grounding rod at least one metre (three feet) into the soil. If soil is dry, sandy, or rocky, use multiple grounding rods connected in series, or water the ground around the rod regularly to maintain soil conductivity. Moist, clay-rich soil provides the best ground contact. Test the fence voltage with a fence tester (a simple, inexpensive tool) — if voltage at the fence is below 3,000 volts, check your grounding first.

Fox-Proofing — How Effective Is Electric Fencing?

Electric poultry netting is highly effective against foxes when properly installed and maintained. A fox encountering an electrified fence receives a sharp shock through its nose or paws — the most sensitive areas — and learns rapidly to avoid the fence. Most foxes do not return after a single encounter.

Effectiveness requires the fence to be live at all times. A fence that is switched off overnight (when foxes hunt), has a flat battery, or is grounded out by vegetation is no protection at all. The fox does not know the fence is supposed to be electric — it only knows whether it received a shock. A single encounter with an uncharged fence teaches the fox that this fence is safe to breach.

Electric netting does not protect against aerial predators. Hawks, buzzards, and other birds of prey are unaffected by ground-level fencing. If aerial predation is a significant risk, additional measures (covered runs, overhead netting, or supervised free-ranging) are needed.

Installation — Setting Up Your First Electric Fence

Step one. Choose your fence line. Walk the planned perimeter and check for obstacles — slopes, rocks, wet ditches, gates, and existing fences that might interfere.

Step two. Install the grounding rod at the energiser location. Drive it at least one metre into the soil. Connect it to the energiser's ground terminal with the supplied cable.

Step three. Unroll the netting along the fence line, pushing each integrated post firmly into the ground as you go. Keep the netting taut — sagging netting allows predators to push underneath and reduces the effectiveness of the electrical deterrent.

Step four. Connect the netting to the energiser's live terminal using the supplied clip or connector.

Step five. Switch on the energiser and test the fence voltage at multiple points along the netting with a fence tester. The reading should be at least 3,000 volts (ideally 4,000+ volts) for effective predator deterrence.

Step six. Clear vegetation. Any grass, weeds, or branches touching the electrified wires drain energy from the system (the vegetation creates a path to ground, reducing the voltage available for a predator contact). Trim or mow along the fence line regularly.

Rotational Grazing — Moving Your Flock to Fresh Ground

One of the greatest advantages of electric netting is its portability. It can be moved in minutes, allowing you to rotate your flock to fresh pasture regularly.

Benefits of rotational grazing for poultry. Fresh ground provides clean grazing — grass, seeds, insects, and worms. It breaks parasite cycles — intestinal worm eggs deposited in droppings need time to develop in soil; moving the flock before the cycle completes reduces reinfection. It distributes manure evenly across the land, fertilising the pasture. It prevents the bare, muddy, over-grazed patches that develop around fixed housing.

How to rotate. Set up the netting in a new position. Move the coop (if using a portable coop or chicken tractor) into the new enclosure. Open the fence at the original location, allow the birds to move to the new area, then recover the old netting. The old ground rests and recovers.

Frequency. Weekly rotation is typical. In wet weather or with larger flocks, more frequent moves prevent ground damage. Watch the condition of the grass — when it is grazed down and the ground shows wear, it is time to move.

Vegetation Management — Keeping the Fence Effective

Vegetation touching the electrified wires is the most common cause of reduced fence performance. Every blade of grass, weed stem, or branch contacting a live wire creates a short circuit to ground, draining energy from the system.

Mow or strim the fence line before installation and maintain it regularly. On a permanent installation, some keepers lay a strip of weed membrane or mulch along the fence line to suppress growth.

The lower wires are most vulnerable — they are closest to ground vegetation. This is why the very bottom wire on most netting is non-conductive — constant ground contact would drain the system entirely.

Multi-Roll Systems — Expanding Your Fenced Area

Multiple rolls of netting can be connected end-to-end using the clips provided, creating a larger enclosed area powered by a single energiser. Most energisers can power two to four rolls of standard netting (100–200 metres total).

When connecting multiple rolls, ensure the energiser output is sufficient for the total length. Longer fence runs have higher resistance and may require a more powerful energiser.

Electric Fencing for Other Livestock

Sheep and goats can be contained with electric strand fencing (individual wires on posts) or netting designed for their height and behaviour. Goats are challenging — they are curious, determined, and test fences persistently.

Pigs respect electric fencing well — a single electrified strand at nose height is often sufficient once the pig has learned the deterrent.

General livestock netting is available in various heights and mesh sizes for different species.

Safety Considerations

Electric fencing is safe when properly installed. The energiser delivers a brief pulse (not continuous current), which is startling but not harmful to humans, livestock, or predators. The energy output is regulated to be below dangerous levels.

Do not connect an energiser directly to mains electricity or to a standard battery. Only use purpose-built fence energisers that produce regulated pulses. Improvised electrical fencing is dangerous and potentially fatal.

Display warning signs at regular intervals along the fence, as required by regulations in most jurisdictions. Anyone approaching the fence should be aware it is electrified.

Keep children informed. The shock is unpleasant but not dangerous for adults or older children. Very young children should be supervised around electric fencing.

Do not use electric poultry netting for turkeys — turkeys can become entangled in the netting and, unlike chickens, may not move away from the shock effectively, leading to injury.

Limitations — What Electric Fencing Cannot Do

No protection against aerial predators. Hawks, buzzards, and other raptors are not deterred by ground-level fencing.

Reduced effectiveness in very dry conditions. Dry soil is a poor conductor. If the ground around the earth rod is very dry, the circuit may not complete effectively, reducing the shock delivered. Water the grounding area during drought.

Not a physical barrier without power. If the energiser fails (flat battery, power cut, vegetation drain), the netting becomes a simple mesh fence — no more secure than standard poultry netting. Predators that encounter an uncharged fence learn that it is harmless.

Requires ongoing maintenance. Vegetation management, battery monitoring (solar/battery units), fence testing, and ensuring connections remain clean and secure are regular tasks.

Comparing Energiser Types at a Glance

Common Electric Fencing Mistakes

Poor grounding. The single most common cause of fence failure. Drive the rod deep, keep the soil moist, and test the voltage.

Not testing the fence. A fence tester costs very little and tells you immediately whether the system is working. Test regularly.

Allowing vegetation to touch the wires. Every contact drains energy. Mow the fence line.

Flat battery (solar/battery systems). If the battery dies overnight, the fence is unprotected during peak predator hours. Monitor battery charge and have a backup plan.

Sagging netting. Loose, sagging netting allows predators to push underneath. Keep netting taut and posts firmly planted.

Switching the fence off overnight. Foxes hunt at dusk and dawn. The fence must be live twenty-four hours a day.

Using domestic extension leads to power the energiser. Outdoor extension leads are not rated for permanent outdoor use. Run insulated electric fence wire from the energiser to the fence — not domestic cable.
