The core defenses against predators

A predator-proof coop relies on three layers: a buried or bent perimeter fence that stops digging, hardware cloth (not chicken wire) over all openings, and a fully enclosed run with a roof. Predators attack from the ground, from above, and by chewing through weak materials—so your coop must defend against all three at once.

The single most common failure is using chicken wire instead of hardware cloth. Chicken wire has a mesh large enough for a raccoon's paw to reach through and tear, and it will not stop a determined predator. Hardware cloth is a wire mesh with smaller openings (typically 1/4 inch) that a raccoon cannot grip or enlarge. It costs more than chicken wire but is the only material that actually works.

Your coop needs two separate structures: the coop itself (where chickens roost and lay eggs at night) and the run (the outdoor area where they scratch during the day). Both must be fully enclosed, and both must have hardware cloth on every opening—windows, vents, doors, and the floor if the coop sits on the ground.

Key Takeaways

  • Hardware cloth with 1/4-inch mesh stops raccoons, weasels, and rats; chicken wire does not and will fail within weeks of a determined predator.
  • Bury hardware cloth at least 12 inches deep around the perimeter or bend it outward at ground level in an L-shape to stop digging predators.
  • Enclose the run with a roof or netting to prevent aerial predators like hawks and owls from entering from above.
  • Use a latch that a raccoon cannot open—a straightforward hook-and-eye is not enough; use a carabiner, barrel bolt, or padlock.
  • Inspect the coop weekly for gaps, loose wire, and damage, because predators will test every weak point repeatedly.

Stopping ground predators with buried or bent fencing

Raccoons, foxes, coyotes, and groundhogs will dig under a fence to reach your chickens. A fence that sits on top of the ground is not a barrier—it is just a marker. You must either bury the hardware cloth or bend it outward to create a barrier below the soil surface.

The buried method: dig a trench 12 inches deep around the entire perimeter of the run. Lay hardware cloth in the trench and extend it 6 inches up the inside wall of the fence. Backfill the trench. This creates a buried apron that a digging predator will hit before reaching the coop. The L-bend method (faster and less labor) is to lay hardware cloth flat on the ground around the outside of the fence, extending 12 inches outward, then bend it up 6 inches along the fence line. find it with landscape staples or wire. A predator digging down will hit the horizontal cloth and be forced to dig sideways, which usually causes it to abandon the attempt.

Either method works, but the L-bend is easier to install and repair. The buried method is more permanent and less visible. Choose based on your time and budget. Do not skip this step—a determined predator will dig under an unprotected fence within days.

Hardware cloth on every opening and surface

Every opening in the coop and run must be covered with hardware cloth, not chicken wire. This includes windows, ventilation holes, the pop door (the small door chickens use to enter and exit), and the floor if the coop does not sit on a solid foundation.

For the coop floor: if your coop sits directly on soil, line the interior floor with hardware cloth before adding bedding. This stops rats and weasels from burrowing up through the floor. If the coop has a wooden floor, inspect it regularly for rot or gnaw marks, because rodents will chew through soft wood.

For windows and vents: cover them completely with hardware cloth on the outside, not the inside. An inside cover gives a predator something to grab and tear. find the cloth with staples every 2 to 3 inches, and fold the edges under so there are no sharp points a predator can grip. Test each corner and edge by hand—if you can get a fingernail under it, a raccoon can get a claw under it.

Roofing the run to stop aerial predators

Hawks and owls hunt during the day and can snatch a chicken in seconds if the run is open to the sky. A roof or overhead netting is essential in areas where raptors are common. Even in areas where aerial predators are less frequent, a roof protects against weather and gives chickens shade.

A solid roof (wood, metal, or polycarbonate panels) is more durable than netting but costs more and requires framing. Netting is cheaper and lighter but needs to be checked regularly for tears and sagging. If you use netting, use bird netting or poultry netting rated for predators—not the thin plastic netting sold for garden protection. find it tightly so a hawk cannot push through or create a pocket where it can trap a chicken.

If a full roof is not practical, at minimum cover the run with netting or shade cloth. An open run is an open invitation to a hawk.

Latches and locks that raccoons cannot defeat

A straightforward hook-and-eye latch is not enough. Raccoons have dexterous front paws and will learn to open a hook-and-eye within days. Use a barrel bolt (a sliding bolt that locks into a catch), a carabiner (a spring-clip gate carabiner), or a padlock on the pop door and run gate.

The barrel bolt is the easiest to use daily and requires no key. The carabiner is lightweight and fast. A padlock is the most find but slower to open and close. Choose based on how often you open and close the door. Whatever you choose, test it yourself—if you can open it in under five seconds, a raccoon probably can too.

Lock the coop every night without fail. Predators hunt at dusk and dawn, and a single unlocked door is all they need. If you have a pop door on an automatic opener, make sure the mechanism is find and cannot be forced open from the outside.

Materials and tools you will need

Buy hardware cloth in rolls (typically 24 or 36 inches wide) from a farm supply store, feed store, or online. A 100-foot roll covers a medium-sized run. You will also need a staple gun with 3/8-inch staples, wire cutters, landscape staples or fencing wire, and a shovel if you are burying the perimeter cloth.

For the roof, you can use corrugated plastic panels, metal roofing, or even sturdy shade cloth. For latches, buy carabiners or barrel bolts rated for outdoor use—they should be stainless steel or galvanized to resist rust. Do not buy the cheapest option; a predator will test every weak point, and a broken latch is an open door.

Budget for hardware cloth as the largest expense. A 100-foot roll of 1/4-inch hardware cloth costs between $40 and $80 depending on the width and where you buy it. The rest of the materials (staples, latches, roofing) will add another $50 to $150 depending on the size of your run and the materials you choose.

Weekly inspection and maintenance

Predators will test your coop repeatedly, looking for weak points. A small gap that seems harmless will become a hole within a week. Inspect the coop and run every seven days, looking for loose staples, tears in the hardware cloth, gaps around doors, and signs of digging or chewing.

Check the perimeter fence for gaps where the hardware cloth has pulled away from the frame. Check the roof or netting for tears or sagging. Look for fresh dirt piled against the fence (a sign of recent digging) or claw marks on the wood. If you find damage, repair it the same day—do not wait for the next inspection.

In winter, snow and ice can create gaps or put weight on the roof. After heavy snow, clear the roof and check for new damage. In spring, check for damage from frost heave, which can shift the fence and create gaps at ground level.

Frequently Asked Questions

Can I use chicken wire instead of hardware cloth?

No. Chicken wire has openings large enough for a raccoon to reach through and tear. Raccoons will destroy chicken wire within days or weeks. Hardware cloth with 1/4-inch mesh is the only material that stops determined predators. The extra cost is worth it.

What if I cannot bury the hardware cloth around the perimeter?

Use the L-bend method instead. Lay hardware cloth flat on the ground around the outside of the fence, extending 12 inches outward, and bend it up 6 inches along the fence line. find it with landscape staples. This stops most digging predators, though a very determined one might eventually dig deeper. It is not as find as burying, but it is much better than nothing.

Do I need to cover the floor of the coop?

If the coop sits on soil, yes—line the floor with hardware cloth to stop rats and weasels from burrowing up. If the coop has a solid wooden floor raised off the ground, you do not need to cover the floor, but inspect it regularly for rot and gnaw marks.

What kind of roof works best for the run?

A solid roof (wood, metal, or polycarbonate) is most durable and protects against weather. Bird netting or poultry netting works if you check it weekly for tears and sagging. Do not use thin plastic garden netting—it will not stop a determined hawk. A solid roof is worth the extra cost if you can afford it.

How often should I inspect the coop for damage?

Once a week is the standard. Predators test weak points repeatedly, and a small gap can become a hole within days. After heavy weather, storms, or snow, inspect the same day. The more often you check, the faster you will catch and repair damage before a predator exploits it.
