Two Containment Philosophies
Electric poultry netting and fixed runs solve the same problem, keeping chickens in and predators out, through fundamentally different approaches. Electric netting creates a psychological barrier that animals learn to avoid after one or two contacts. Fixed runs create a physical barrier that prevents passage regardless of the animal's willingness to approach. Each approach has distinct advantages and limitations that make it better suited to certain properties, flock management styles, and predator environments.
Electric Netting
Electric netting consists of horizontal wires woven into a lightweight mesh fence, typically 42 to 48 inches tall, with built-in posts that push into the ground for easy setup and relocation. An energizer pulses electricity through the wires, delivering a sharp but harmless shock to anything that contacts the fence. The shock trains predators to avoid the fence after one or two encounters, creating an effective deterrent zone around the enclosed area.
The primary advantage of netting is flexibility. You can move it weekly to provide fresh pasture, reconfigure the shape to accommodate different yard layouts, and take it down entirely when not needed. For rotational grazing systems, electric netting is the only practical containment option because building and rebuilding permanent fencing every week is obviously impossible. Setup takes 15 to 30 minutes for a single person.
Fixed Run
A fixed run is a permanent structure of posts, framing, and hardware cloth that creates an enclosed outdoor space attached to the coop. Once built, it requires no daily management, no energizer, and no repositioning. The physical barrier of hardware cloth stops every predator that is not strong enough to tear through the wire, which effectively means everything except bears. A covered fixed run also protects against aerial predators, which electric netting does not address.
The limitation of fixed runs is inflexibility. The birds access only the enclosed area, which becomes bare dirt, compacted, and parasitically loaded over time without rest periods. A fixed run that is too small for the flock size creates health and behavioral problems that a rotational netting system avoids by providing fresh ground regularly.
Cost Comparison
Electric netting is cheaper upfront for equivalent enclosed area. A 164-foot roll enclosing roughly 1,600 square feet costs 200 to 250 dollars plus 50 to 200 dollars for the energizer. A permanent run enclosing the same area with hardware cloth, pressure-treated posts, and framing costs 800 to 2,000 dollars or more in materials alone. However, the permanent run has no ongoing electricity cost and no replacement cost for worn netting, which typically needs replacement every five to eight years.
The Verdict
Choose electric netting if you want rotational grazing, have a large property, and are willing to manage the energizer and periodic netting relocation. Choose a fixed run if you want set-and-forget containment, need aerial predator protection, or do not want to manage an electric fence system. Many keepers use both: a fixed run attached to the coop for daily use with the option to deploy electric netting for supervised free-ranging sessions or seasonal pasture rotation.
Predator Protection Comparison
Electric netting excels against ground predators that learn to avoid the shock. Foxes, coyotes, dogs, and raccoons are effectively deterred after one or two contacts with a properly energized fence. However, electric netting provides no protection against aerial predators because the top is open. Hawks, owls, and eagles can attack freely over the netting. A fixed run with a covered top provides complete protection against both ground and aerial predators, making it the superior choice in areas with heavy raptor pressure.
De-energized netting is worse than no fence at all because it gives a false sense of security. A predator that has learned to avoid the shock will test the fence periodically. If the energizer fails, the battery dies, or vegetation grounds the fence, the predator finds no shock and walks through the lightweight mesh that offers zero physical resistance. Fixed runs with hardware cloth stop predators physically regardless of power status. The reliability advantage of a passive physical barrier over an active electrical one is significant for keepers who travel or cannot monitor their energizer daily.
Ground Health and Pasture Rotation
The biggest health advantage of electric netting is the ability to rotate to fresh ground. Parasites, pathogens, and ammonia accumulate in soil that chickens use continuously. Moving the netting to a new section of yard every one to four weeks breaks parasite cycles, allows the previous area to recover, and gives birds access to fresh vegetation and insects. Fixed runs cannot provide this benefit without constructing multiple runs and alternating access, which is expensive and space-intensive compared to simply repositioning netting.
For keepers on properties of half an acre or more, the rotational benefits of electric netting make it the clearly superior option for flock health. For keepers on small urban lots where there is nowhere meaningful to rotate to, the fixed run provides adequate containment without the ongoing management of an electric fence system that has limited space to exploit.
Consider a hybrid approach that maximizes the advantages of both systems. Build a small fixed run attached to the coop for daily use, ensuring birds always have a secure outdoor space available. Add electric netting for weekend supervised free-ranging sessions when you are home to manage the system. This combination provides the reliability and convenience of a fixed run for daily security with the rotational grazing benefits of netting when time and attention are available to manage it properly.
Frequently Asked Questions
Does electric netting really keep predators out?
Yes. Properly installed and energized electric netting deters foxes, coyotes, raccoons, and dogs effectively. The psychological deterrent of the shock is more powerful than the physical barrier. However, netting must be properly grounded and energized to work. De-energized netting provides no protection.
How much does electric netting cost?
A 164-foot roll of poultry-height electric netting costs 150 to 250 dollars. An energizer adds 50 to 200 dollars. Total setup cost for a basic system is 200 to 450 dollars, compared to 500 to 2000 dollars for a comparable permanent run with hardware cloth and framing.
