The short answer: plug-in near an outlet, solar far from one, and grounding either way

For a chicken run with electric netting, pick the energizer by where the fence sits. Premier1, a poultry-fence retailer, advises plug-in units if the fence is near an outlet and solar units if it is far from one. Whichever you choose, the energizer has to suit the netting, be grounded properly, and keep enough power at the fence when grass and weeds touch the bottom strands. Check the netting maker's instructions and the energizer's manual before you buy, and treat any electrical hookup as a job for a qualified electrician if it goes beyond plugging into a protected outlet.

This guide is about the energizer, also called a charger, and its grounding gear, not the netting. For the netting itself, see our electric poultry netting roundup and our comparison of electric netting versus a fixed run.

Solar, plug-in and battery: how to choose

Premier1's energizer guide is retailer content, so these are the company's views, not independent standards. It describes all-in-one solar units as battery-powered energizers recharged by a panel on the case, portable and quick to set up. It says plug-in and battery units cost less and suit shaded areas, and recommends plug-in if the fence is near an outlet and solar if it is far from one.

For a plug-in unit, the outlet matters as much as the energizer. Check the energizer’s manual for its outdoor-use directions, and have a qualified electrician add any outdoor outlet. Read our guide on outdoor-rated cords and fire safety for the cord basics, and do not run an ordinary indoor cord to the fence.

For solar, look at where the sun falls on the panel through the day, including in winter. A panel in the shade of the coop or a tree charges poorly. Moving the energizer to a sunnier post can fix that without a bigger unit.

Matching the energizer to the netting

Netting makers often pair their netting with specific energizers, and some sell kits. Read both manuals. Do not assume that any energizer works with any netting.

• Check the netting maker's guidance on energizer type and output for the length of netting you plan to run.
• Check the energizer's rating for fence length and weeds. Premier1 says total fence length matters little and that "miles of fence" ratings on farm store labels can mislead. It lists how much weedy fence an energizer can handle instead.
• Plan for the worst day. Wet grass touching the netting drains more power than dry grass, so a unit that works on a bare lawn may struggle in June.
• Buy to the manual's limit, not the minimum. If you may add a second run later, think now about whether the unit can handle it.

Premier1 also says low wires, those 3 to 6 inches above the ground, leak more than wires above 18 inches. Poultry netting has lower strands by design, so keeping vegetation trimmed along the bottom matters more than with a tall fence. Our guide to chicken run fencing covers the fixed alternatives.

Grounding: the part most setups skimp on

An electric fence is a circuit, and the ground is half of it. Premier1 says dry, sandy or rocky soil raises resistance and weakens the pulse, and suggests more ground rods, a positive and negative fence design or a higher-output energizer as fixes. It gives no number of rods or spacing, so follow your energizer's manual for the rod count and spacing it requires.

• Use the ground rods the manual calls for and the clamps and wire it specifies.
• Keep the energizer ground away from utility grounds. A Clemson University agricultural safety post (unsigned) says energizer grounds should be at least 65 feet from utility grounds.
• Contact 811 before you drive rods. The national 811 service says it is free and asks that you contact it a few business days before any digging.
• Test it. A fence tester shows whether voltage is reaching the far end. Check the tester's directions, and test after rain and in dry spells.

Safety and fire: respect the fence

Chicken fencing is meant to deter predators, but an energized fence is still an electrical hazard and needs care.

• Never touch the wires or step over the fence. Premier1 warns never to place your head or upper spine near an energized wire and never to step over or climb through an energized fence. Keep young children away from electrified fences.
• Do not connect more than one energizer to a fence. The Clemson post says not to.
• Keep flammable material away. The Clemson post notes fences can throw sparks, so keep flammable objects away, and use low-power mode in drought if the energizer has one.
• Avoid continuous-current and weed-burner energizers. Premier1 advises against them and warns that continuous current can create a long spark that can ignite grass or weeds touching the fence. The same page says brief pulses almost never pose a fire risk near combustible material. Fire risk is real if the wrong unit is used or vegetation is left to touch the wires, so check the manual.
• Do not use barbed wire. The Clemson post says it increases the risk of entanglement.
• Post warning signs. The Clemson post says to post warning signs every 300 feet where the public has access, for example along roads. Check your local rules for anything stricter.

Local rules on electric fences vary, and some places regulate them. Check your city, county or homeowner association before you install one. Our guide to where to put a coop covers placement and neighbor sightlines.

Keeping it working through the seasons

An energizer you never check will fail the day you need it. A simple routine:

1. Test the fence on a schedule and after storms. A tester takes seconds. The schedule is our suggestion, not a figure from a source.
2. Trim along the bottom strand. Wet grass drains power.
3. Inspect connectors and the ground. Look for corrosion, loose clamps and broken wires.
4. Look after the battery or panel. Check the manual for storage and winter notes.
5. Re-check after snow. Snow can ground the bottom strand. Our guide to winter predator pressure covers the season.

Penn State Extension notes that some keepers run electric fencing around the outside of a pen about 4 inches off the ground and about one foot from the main fence, to discourage predators. A powered fence is one layer. Pair it with solid latches and secure night housing, and see our guide to protecting a coop from raccoons and hawks.
