Quick Answer: Predator-proofing a chicken coop means five things done together, not one silver bullet: cover every wall, window, and vent in ½-inch, 19-gauge hardware cloth instead of chicken wire; bury or skirt a 12-inch apron around the base so diggers can’t tunnel under; replace simple hook latches with a carabiner clip or two-step lock, since raccoons can open basic hooks with their paws; close the coop every evening with a timer- or light-sensor automatic door, since most losses happen at dusk; and cover the run’s roof, not just its walls, to block hawks and owls. Skip any one of these and a predator will eventually find that exact gap.
Most “predator-proof” coops still get raided, and it’s almost never because the owner did nothing — it’s because they did four things right and left one gap: chicken wire instead of hardware cloth on a single vent, a latch a raccoon can flip, a door that stayed open one evening too late, or a run with solid walls but an open top. Predators are opportunists that test a coop’s entire perimeter, not just the parts that look secure. This checklist walks through the fixes that close every common gap, in the order to tackle them.

Predator-proofing checklist at a glance
| Threat | What it exploits | Fix | What to use |
|---|---|---|---|
| Reachers (raccoon, weasel) | 1-inch chicken-wire gaps, unscreened windows | Cover walls, windows, vents | ½" 19-gauge hardware cloth |
| Diggers (fox, raccoon, dog) | Unprotected ground under walls | Bury or skirt the base | 12-inch hardware-cloth apron + landscape staples |
| Simple latches | Raccoon paw dexterity | Lock every door and hatch | Carabiner clip or two-step locking latch |
| Dusk lapses | Door left open past sunset | Close the coop automatically | Timer/light-sensor auto-door |
| Aerial (hawk, owl) | Open-topped run | Cover the run overhead | Run cover or overhead netting |
| Snakes, mice | ½-inch mesh is still too wide | Finer mesh on nest boxes | ¼" hardware cloth on nest boxes |
| Unidentified visitors | No visibility overnight | See what's testing the coop | Night-vision coop camera |
Predator-proofing by the numbers
- Predators cause more backyard-flock losses than disease or weather combined, according to USDA and state extension guidance — and nearly every loss traces back to one unprotected gap rather than a coop that was left completely open.
- Raccoons typically don’t break in — they reach in. Ohio State University Extension documents that raccoons on the outside of undersized mesh usually reach through the openings to grab a bird’s head or leg rather than climb or tear their way through, which is exactly the failure mode ½-inch hardware cloth is built to stop and 1-inch chicken wire is not.
- A 12-inch apron stops diggers. Extension predator-proofing guidance recommends burying hardware cloth about 12 inches deep, or laying a 12-inch outward skirt at the base, so foxes, raccoons, and dogs hit buried mesh instead of tunneling straight under the wall.
- Most predator activity runs from dusk to dawn. Raccoons and foxes are largely nocturnal hunters, per extension wildlife guidance, which is why a coop door closed even one evening late is a real risk window, not a rounding error.
1. Swap chicken wire for ½-inch hardware cloth — everywhere
½" 19-Gauge Galvanized Hardware Cloth
- ½-inch openings are too small for a raccoon's paw or a weasel's body — the standard predator-proofing spec.
- Cover every wall panel, window, and vent, not just the obvious ones — predators find the one gap you skip.
- Chicken wire is fine for daytime perimeter fencing, but it should never be the coop's actual night-time barrier.
Chicken wire is designed to keep chickens in; it does almost nothing to keep predators out. Its roughly 1-inch hexagonal openings are wide enough for a raccoon to reach a full paw through or a weasel to squeeze its entire body through, and it tears easily under a determined claw. Hardware cloth is welded steel mesh with much smaller, rigid openings, and ½-inch is the standard because it’s tight enough to block a raccoon’s reach while staying affordable to cover a whole coop and run in.

Ordering enough hardware cloth, latches, and an apron’s worth of landscape staples for a full predator-proofing pass?

2. Bury or skirt a 12-inch apron so diggers can’t tunnel under
Galvanized Landscape Staples / Garden Fabric Pins
- Pin a 12-inch outward skirt of hardware cloth flat around the coop and run base instead of digging a trench, if the ground is hard to excavate.
- Grass grows through the mesh within a season and hides it, so it doesn't have to look unfinished long-term.
- Works alongside a buried apron for extra-determined diggers like foxes in sandy or loose soil.
Walls and vents covered in hardware cloth still leave one gap most keepers overlook: the ground itself. Foxes, raccoons, and dogs that can’t get through a wall will often try to dig underneath it instead, so the fix is to extend the barrier below grade — bury a foot of hardware cloth vertically along the perimeter, or bend it into an L-shaped skirt that lays flat and extends 12 inches out from the base, pinned down with landscape staples. Either method puts mesh in the way of a digging predator before it ever reaches the wall.
3. Replace simple latches with a lock a raccoon can’t work
Carabiner Clips / Two-Step Locking Coop Latches
- Clip a carabiner over any existing hook-and-eye or slide-bolt latch — cheap, fast, and effective on its own.
- Purpose-built two-step locking latches require a push-and-slide or push-and-turn motion a raccoon's paws can't replicate.
- Check every door and hatch, not just the main one — nest-box lids and feed hatches need the same upgrade.
A coop can be wrapped in perfect hardware cloth and still get raided through the front door, because raccoons are dexterous enough to flip a simple hook-and-eye latch open with their front paws — a well-documented failure point in predator-proofing guidance. A carabiner clipped over the hook is the fastest, cheapest fix, and a purpose-built two-step latch that needs a push-and-slide or push-and-turn motion is the more permanent upgrade. Check every access point on the coop, not just the main door — nest-box lids and feed hatches are common blind spots. See our best chicken coop latches guide for a full comparison, including a no-key combination lock option.
4. Automate the door so it closes every evening, no exceptions
Most predator losses trace back to one specific human-error window: a door left open past dusk, whether from a late night out or simply forgetting. Raccoons and foxes are largely nocturnal hunters and are already active by the time a coop door should be closed, so a timer- or light-sensor-based automatic door removes that risk entirely — it closes at the same window every evening whether or not anyone’s home to do it. See our best automatic chicken coop door guide for the specific models worth buying.
5. Cover the run overhead — walls alone don’t stop hawks and owls
Hardware cloth on the walls does nothing against a predator that attacks from above. Hawks and owls are the main daytime and dusk threat to a run with an open top, striking straight down where wall-level mesh offers zero protection. A solid roof panel, a welded run cover, or heavy-gauge netting stretched over the top closes that gap — see our best chicken run cover guide for options sized to different run footprints. If the flock free-ranges beyond the run, a fully enclosed chicken tunnel gives them extra covered ground without leaving them exposed the way an open yard does.
6. Drop to ¼-inch mesh on nest boxes and vulnerable openings
Half-inch mesh stops mammals but still lets a small snake or mouse through, and both go straight for eggs and chicks. Run a band of finer ¼-inch hardware cloth around nest-box vents and any low openings near the ground, backed by the standard ½-inch cloth everywhere else. Our best nesting boxes for chickens guide covers boxes designed with predator access already in mind.
7. Add a camera to see exactly what’s testing the coop
Torn mesh or a bent latch in the morning tells you a predator tried — not which one, or how close it came to succeeding. A night-vision coop camera lets you check overnight footage and identify the specific animal testing your perimeter, so you can reinforce the exact spot it’s working instead of guessing. Our best chicken coop camera guide compares models built for coop conditions.
The bottom line
Predator-proofing a chicken coop is a system, not a single product: ½-inch, 19-gauge hardware cloth on every wall, window, and vent; a 12-inch buried or skirted apron so diggers can’t tunnel under; a carabiner or two-step latch on every door, since raccoons can open simple hooks; an automatic door that closes at dusk without fail; and a covered run roof for hawks and owls. Do all five and the coop closes off the gaps predators actually exploit — do four out of five, and sooner or later something finds the one you skipped.
