6 Best Predator Proof Chicken Runs For Free Range Chickens That Outsmart Foxes
Secure your free-range flock from clever foxes. We review the 6 best predator-proof chicken runs, highlighting key designs that prevent digging and climbing.
There’s no worse feeling than seeing the scattered feathers and knowing a fox has paid a visit. You provide your flock with plenty of space to roam, but their "safe zone" has to be an absolute fortress when they’re locked up. A truly predator-proof run isn’t just a fence; it’s a security system designed to defeat an animal that is smarter and more persistent than most people realize.

Key Features of a Truly Fox-Proof Chicken Run
A fox thinks in three dimensions: it will dig under, climb over, or tear right through a weak point. Standard chicken wire is a perfect example of a false sense of security. It’s designed to keep chickens in, not to keep a determined predator with sharp teeth out.
Create beautiful floral arrangements and protect your garden with this durable chicken wire. The 15.7" x 157" galvanized and PVC-coated mesh is easy to cut and shape for crafts, enclosures, and garden barriers.
The foundation of a secure run rests on three non-negotiable elements. First, the mesh must be 1/2-inch or 1/4-inch hardware cloth, a rigid, welded wire that a fox cannot break or squeeze through. Second, the run needs a secure top, whether a solid roof or a tightly fitted hardware cloth ceiling. Third, every latch must be a two-step, predator-proof carabiner or slide bolt, not a simple hook-and-eye that can be rattled open.
Finally, you have to address the ground. A fox’s first instinct is to dig at the base of the fence. A run that simply sits on the grass is an open invitation. The solution is a "predator apron," a skirt of hardware cloth extending outward from the base of the run, which is the single most effective defense against digging.
Omlet Walk-In Run: Ultimate Modular Fox Defense
The Omlet Walk-In Run is what you get when engineers, not just welders, design a chicken run. Its greatest strength is that it’s a complete, integrated system. The powder-coated steel mesh panels are strong, and crucially, the design includes a built-in, anti-dig skirt that lays flat on the ground around the entire perimeter.
This isn’t a cheap option, but you’re paying for convenience and proven design. The modularity is a huge advantage; you can start with a 6×6 run and easily add sections as your flock grows. Features like the stable-style door, which lets you enter without a chicken slipping past your legs, show a deep understanding of the daily realities of chicken keeping.
The main tradeoff is the price and perhaps the feel of the wire. While incredibly tough, the panel system doesn’t have the sheer heft of a 2×4 and hardware cloth build. However, for someone who wants a secure, expandable, and easy-to-assemble solution right out of the box, the Omlet is arguably the best-in-class.
OverEZ Chicken Run: The Easiest Secure Setup
Protect your chickens with this durable, walk-in run. The steel-built pen keeps predators out, provides excellent ventilation, and easily connects to your existing coop.
OverEZ has built its reputation on making coop and run assembly incredibly simple, and this run is no exception. It’s a handsome, sturdy structure with a solid wood frame and pre-attached wire mesh panels. If you want a secure run that you can put together in an afternoon without a lot of fuss, this is a top contender.
The design is straightforward and robust, creating a secure box that pairs perfectly with their line of coops. The black-coated hardware cloth is a significant step up from flimsy chicken wire, offering real protection against tearing. The height is also generous, making access for cleaning and feeding much easier than in shorter runs.
However, the OverEZ run is a fantastic starting point, not a complete fox-proof solution out of the box. It lacks a built-in predator apron. To make it truly secure against a digging fox, you absolutely must purchase and install a hardware cloth skirt around the entire base. It’s a crucial extra step, but one that turns a very good run into a great one.
Producers Pride Universal Pen: Top Value Choice
You’ll find these pens at farm supply stores, and they represent the absolute best value in terms of square footage for your dollar. Often sold as dog kennels, these chain-link pens provide a large, tall, and sturdy frame that can be transformed into a formidable chicken fortress.
The trade-off for the low price is the need for significant modification. The standard chain link, while strong, can have openings large enough for a raccoon to reach through or a small weasel to squeeze through. More importantly, the pen has no floor and no protection against digging predators. You are essentially buying a skeleton.
To make it fox-proof, you must budget for extra materials and labor. Wrap the bottom three to four feet of the entire pen in 1/2-inch hardware cloth, securing it tightly with zip ties or wire. Then, install a wide, 24-inch hardware cloth apron around the entire perimeter, staked firmly to the ground. It’s a weekend project, but it results in a massive, secure run for a fraction of the cost of other options.
Advantek Courtyard Pen: Best for Small Flocks
For the backyard keeper with three to five birds, a massive walk-in run can be overkill. The Advantek Courtyard Pen hits a sweet spot, offering a secure, contained space that’s more robust than the flimsy runs attached to most all-in-one coops. Its steel frame and weatherproof cover provide a safe place for a small flock to enjoy the outdoors.
The main benefit here is its self-contained and compact design. The assembly is straightforward, and the latching system is generally more secure than what you find on budget-friendly coops. It’s a significant upgrade that provides real peace of mind for someone with limited space.
Like many pre-fabricated runs, its primary vulnerability is at ground level. It provides no inherent protection against digging. A simple hardware cloth apron staked around the perimeter is a necessary addition to make it truly fox-proof. Think of it as a secure daytime lounge, not a full-time residence, and ensure it’s fortified at the base.
Eglu Cube Run: Secure, Movable Pasture Grazing
The Eglu system approaches security from a different angle: mobility. The run is designed to integrate seamlessly with the Eglu Cube coop, creating a single unit that can be moved to fresh pasture every few days. This is the "chicken tractor" concept, refined and made incredibly user-friendly.
The security features are top-notch and built-in from the start. The heavy-gauge steel mesh is tough, and like its larger Omlet cousins, the run includes a wide, integrated anti-dig skirt. This is absolutely essential for a movable run, as you can’t install a permanent buried apron. The secure locking mechanisms and solid construction leave no weak points for a predator to exploit.
The obvious tradeoff is size. The standard run is relatively small, as it’s intended for frequent moves. While you can buy extensions to create a larger static run, the system’s core strength lies in its mobility. This is the ideal solution for someone who wants to practice rotational grazing on a small scale without ever compromising on predator security.
Snap Lock Formex Run: Weatherproof & Expandable
If you’re tired of wood that rots and metal that rusts, the Formex run is an interesting alternative. Made from a durable, UV-resistant polymer, this run is designed to withstand the elements without the maintenance required by traditional materials. It’s a modern solution to an age-old problem.
Its key features are the simple, tool-free "snap lock" assembly and its modular design. You can easily connect additional panels to expand the run as your flock grows. The material is also exceptionally easy to spray down and clean, which is a big plus for coop hygiene.
While the walls and top are secure, the base is its Achilles’ heel. Like most runs in this category, it ships without any defense against digging. You are buying a secure frame that must be fortified at ground level. Installing a 24-inch hardware cloth apron is not optional; it’s a mandatory step to protect your flock from a fox.
Reinforcing Your Run: Hardware Cloth & Aprons
No matter which commercial run you buy, you can almost always make it better. The difference between a good run and a great, fox-proof run often comes down to two key reinforcements: upgrading the mesh and adding a predator apron.
Let’s be clear: chicken wire is not a security material. A fox or raccoon can rip right through it. For true security, the bottom 3 feet of any run should be made of, or reinforced with, 1/2-inch welded hardware cloth. This small, rigid mesh stops teeth, claws, and squeezing bodies in their tracks.
The predator apron is the most critical upgrade for stopping a fox. It’s a simple skirt of hardware cloth, at least 12 to 24 inches wide, laid flat on the ground around the outside perimeter of your run and secured with landscape staples. A fox’s instinct is to dig directly at the fence line. When its paws hit this underground mesh a few inches away from the wall, it can’t get the leverage to dig under, and it almost always gives up. This single, simple addition will defeat the vast majority of digging predators.
Choosing the right run is a balance of your budget, your flock size, and how much DIY work you’re willing to do. A great commercial run provides the frame, but true security comes from understanding a predator’s methods. By reinforcing the base with hardware cloth and installing a proper apron, you can turn almost any good run into a fortress that lets you, and your chickens, rest easy.
