How to Predator-Proof a Chicken Coop: Mesh, Aprons, Latches and More
Last updated: November 2026 · From the KRMPLANS team, designers of DIY building plans
Quick answer: To predator-proof a chicken coop, cover every opening with 1/2-inch galvanized hardware cloth (not chicken wire), add a buried or surface apron 12 to 24 inches wide around the base, use two-step latches raccoons can't open, roof the run, seal any gap wider than 1/4 inch, and lock the flock inside every night before dark.
Most flock losses happen at night, through an opening the owner did not think was big enough to matter. If you are building a new coop or upgrading an existing one, this guide walks through the predators you are likely to face, the materials that actually stop them, and a simple routine that closes the remaining gaps. It also includes a table to help you identify what attacked your birds if you have already had a loss.
Key Takeaways
- Chicken wire keeps chickens in. It does not keep raccoons, dogs, or weasels out. Use 1/2-inch hardware cloth.
- Stop diggers with a hardware cloth apron buried 12 to 18 inches deep or laid flat 12 to 24 inches outward.
- Raccoons can open hook-and-eye latches and simple slide bolts. Use carabiner-clipped or keyed latches.
- Hawks and owls hunt from above, so a fully roofed or netted run is the only reliable fix.
- Any gap over about 1/4 inch can admit snakes, weasels, or rats. Seal them.
- Shut the birds in every night, ideally with an automatic coop door as backup.
Which Predators Attack Backyard Chickens?
The most common chicken predators in the United States are raccoons, foxes, coyotes, hawks, owls, snakes, rats, weasels and minks, opossums, skunks, and loose dogs. Which ones matter most depends on your region, but almost every backyard has at least three of them nearby.
The University of Maryland Extension notes that owls take birds during the night, hawks hunt during the day, opossums and skunks prey at night, and raccoons will reach through openings. That last point is the reason so many coops fail: a raccoon does not need to get inside to kill a bird sleeping near the wire.
Predators by how they get in
- Climbers and grabbers: raccoons, opossums, cats. They open latches and reach through mesh.
- Diggers: foxes, coyotes, dogs, skunks. They tunnel under walls and fences.
- Squeezers: weasels, minks, snakes, rats. They fit through holes the size of a coin.
- Aerial hunters: hawks during the day, owls at dusk and night.
What Mesh Should You Use to Keep Predators Out?
Use 1/2-inch galvanized hardware cloth, 19 gauge or heavier, on every window, vent, and run wall. Standard chicken wire has 1-inch or larger hexagonal openings and thin wire that raccoons can tear and dogs can push through.
Attach hardware cloth with screws and fender washers or with wood battens screwed over the edges, not with light staples alone. A determined raccoon can pull stapled mesh loose at a corner. Overlap seams by at least 2 inches and fasten every 4 to 6 inches.
Many builders use 1/4-inch hardware cloth on the lower 2 feet of run walls in areas with snakes or rats, then switch to 1/2-inch above. Remember that every vent you add for airflow is also a potential entry point. Our chicken coop ventilation guide explains how to size vents so you can cover all of them with mesh without starving the coop of air.
| Material | Opening Size | Stops | Does Not Stop |
|---|---|---|---|
| Chicken wire (poultry netting) | 1 to 2 in hex | Keeps chickens contained, deters some hawks overhead | Raccoons, dogs, weasels, snakes, rats |
| 1/2-in hardware cloth, 19 ga | 1/2 in square | Raccoons, foxes, dogs, most weasels, larger snakes | Small rats and small snakes in some cases |
| 1/4-in hardware cloth | 1/4 in square | Nearly all mammals and most snakes | Little, but costs more and restricts airflow slightly |
| Welded wire fence, 2x4 in | 2 x 4 in | Large dogs, coyotes as an outer fence | Raccoons, weasels, snakes, rats |
| Hawk or aviary netting | Varies | Hawks and owls from above | Climbing and digging predators |
How Do You Stop Predators From Digging Under the Coop?
Install a hardware cloth apron around the entire perimeter of the coop and run. You can bury it vertically 12 to 18 inches deep, or lay it flat on the ground extending 12 to 24 inches outward from the wall and cover it with soil, sod, or pavers.
University of Maryland Extension recommends that you dig a trench 12 inches to 1.5 feet deep around the entire coop and bury hardware cloth there to prevent digging predators. The flat "skirt" method is often easier because it requires no deep trench. Diggers start at the wall, hit the mesh, and give up.
For raised coops, also wrap the space under the floor or add hardware cloth beneath the floor framing. Utah State University Extension suggests integrating heavy-gauge wire mesh beneath the subflooring to discourage entrance of predators.
How to Predator-Proof a Coop, Step by Step
- Walk the coop at night with a flashlight. Look for light leaking out, gaps at the eaves, and spaces under doors. Rats and weasels can use holes the size of a quarter.
- Replace chicken wire with 1/2-inch hardware cloth on windows, vents, and run walls. Fasten with screws, washers, or battens.
- Add the apron. Bury it 12 to 18 inches or lay it flat 12 to 24 inches outward around every wall.
- Upgrade every latch. Use two-step latches, spring-loaded barrel bolts with a carabiner through the hole, or padlock hasps. Raccoons have nimble paws and can open hook-and-eye latches and plain slide bolts.
- Roof the run. Use solid roofing, hardware cloth, or at minimum hawk netting to block hawks and owls.
- Seal gaps over 1/4 inch with hardware cloth, wood trim, or expanding-foam-backed flashing, especially near roosts and nest boxes.
- Install an automatic coop door on a light sensor or timer, and check that it closes fully every evening.
- Remove attractants. Store feed in metal cans with tight lids, collect eggs daily, and clear brush where predators can hide near the coop.
Does a Chicken Run Need a Roof?
Yes, if hawks or owls live in your area, which covers most of the country. A roofed or fully netted run is the only reliable defense against aerial predators, and a solid roof also keeps the run drier.
A fully enclosed run built from hardware cloth on all sides, including the top, protects against nearly every daytime predator, which lets you leave the pop door open while you are at work. For layout and sizing ideas, see our chicken run size and design guide.
If you are planning a new build, it is far easier to frame a covered run from the start than to retrofit one. The saltbox chicken coop plans include a 16x8 walk-in coop with a 16x10 covered run, and the barn chicken coop plans with two runs pair a 10x12 walk-in coop and storage loft with two separate runs. KRMPLANS plans come as instant-download PDFs with framing drawings, a shopping list, and a cut list, so you can add hardware cloth and an apron to the material order before you start.

What Killed My Chicken? Predator Signs Table
Predator signs can point you toward the culprit, but they overlap, so treat this table as a starting point rather than a diagnosis. University of Maryland Extension advises owners to look for footprints, scattered feathers, and egg shells left behind, and notes that weasels tend to bite at the vent region.
| Predator | When | Typical Signs | Main Defense |
|---|---|---|---|
| Raccoon | Night | Birds pulled partly through wire, heads or crops eaten, latches opened | Hardware cloth, two-step latches |
| Fox or coyote | Dusk, night, early morning | Whole bird missing, feather trail, digging at base | Apron, locked coop at night |
| Hawk | Daytime | Plucked feathers in a pile in the open run | Roofed or netted run |
| Owl | Night | Head or neck eaten, bird taken from an open run | Roofed run, birds locked in |
| Snake | Day or night | Eggs or chicks gone with no shells left | 1/4-in mesh low, sealed gaps |
| Rat | Night | Missing eggs or chicks, burrows, chewed feed bags | Sealed feed, 1/4-in mesh, apron |
| Weasel or mink | Night | Several birds killed, bites at neck or vent, little eaten | Gaps sealed to 1/4 in |
| Dog | Often daytime | Many birds killed or injured, mostly not eaten, fence pushed in | Sturdy fencing, apron, hardware cloth |
Common Mistakes to Avoid
- Trusting chicken wire. It is the single most common cause of raccoon losses.
- Stapling mesh with light staples. Use screws with washers or battens.
- Leaving the pop door open "just tonight." Predators patrol on a schedule and find the one night you forget.
- Forgetting the vents. High gable and eave vents are an easy entry for raccoons that climb.
- Relying only on an automatic door. Check it at dusk. Doors jam on bedding, ice, or a hen standing in the frame.
- Leaving feed out overnight. Spilled feed draws rats, which draw snakes.
Choosing rot-resistant framing also matters, because soft, rotted wood lets predators pry mesh loose. Our best wood for a chicken coop guide covers durable options.
Frequently Asked Questions
Is chicken wire enough to keep predators out?
No. Chicken wire is designed to keep chickens in, not predators out. Raccoons can tear it or reach through it, and dogs can push through it. Use 1/2-inch galvanized hardware cloth for any wall, window, or vent that predators can reach.
How deep should I bury hardware cloth around a chicken coop?
Bury hardware cloth 12 to 18 inches deep around the full perimeter, or lay it flat on the surface extending 12 to 24 inches outward and cover it with soil or pavers. Both methods stop most foxes, dogs, and skunks from digging in.
What latch can raccoons not open?
Raccoons struggle with two-step latches, such as a spring-loaded barrel bolt with a carabiner clipped through it, or a hasp with a padlock. Avoid hook-and-eye latches and plain slide bolts, which raccoons can learn to open.
Do automatic chicken coop doors help with predators?
Yes. An automatic door closes the coop at dusk even if you are late getting home, which removes the most common cause of nighttime losses. Check it regularly, since bedding, ice, or a bird in the doorway can stop it from closing fully.
What is killing my chickens at night but not eating them?
Several birds killed with little eaten often points to a weasel, mink, or dog, while raccoons often eat the head or crop. Check for small gaps, look for tracks, and lock the flock in a fully meshed coop until you find the entry point.
