Predator-Proofing Your Coop: What Actually Works

If you keep chickens long enough, you will meet a predator. It might be a raccoon that reaches through a wire gap, a hawk that drops out of the sky, a fox in daylight or a neighbor's dog. A hen that looks safe in the evening can be gone by morning. The good news is that most predator losses are preventable with decent construction and one boring habit: closing the coop every night.

This guide covers the common predators, the materials that work, how to secure a coop and run and the daily routines that keep flocks safe. Predators vary by region, so talk to your local extension office, state wildlife agency and neighbors about what you are likely to face.

Know Your Predators

• Raccoons. Smart and dexterous, with hands that can open simple latches and reach through wire. They often attack at night.
• Foxes and coyotes. Dig, jump and squeeze under gaps, and may hunt at dawn or dusk, sometimes in daylight.
• Hawks and owls. Strike from above. Hawks hunt in daytime, owls at night.
• Weasels, mink and rats. Can squeeze through very small holes.
• Snakes. Often take eggs and chicks.
• Dogs. Neighborhood dogs, and sometimes your own, can kill birds.
• Opossums and skunks. Raid eggs and sometimes attack birds.

Some predators, including many hawks and owls, are protected by law, which means you cannot legally trap or shoot them. Check with your state wildlife agency for the rules in your area.

Use Hardware Cloth, Not Chicken Wire

Chicken wire keeps chickens in, but it does not keep predators out. A raccoon can tear it, and small animals can squeeze through the openings. Use welded hardware cloth, typically half-inch mesh, on windows, vents and any opening, attaching it with screws and washers rather than staples. For runs, hardware cloth is the safer choice, though more costly than poultry netting.

Stop Diggers

Predators that dig, such as foxes, dogs and rats, can tunnel under a fence. Two common solutions are burying hardware cloth a foot or more underground, or laying an apron of hardware cloth extending outward from the base of the run, perhaps a foot or two, and covering it with soil or stones. An apron stops animals from digging at the fence line. A concrete footing or a layer of pavers around the coop also works.

Cover the Run

An open-top run invites hawks, owls and climbing predators. Cover the run with hardware cloth, welded wire or sturdy netting, depending on your risk. Many keepers also put hardware cloth skirts, shade cloth or cover on part of the run so hens can duck for cover. Hens kept under tree branches or with a rooster may do better, but nothing replaces solid overhead protection.

Latches That Defeat Raccoons

A simple slide bolt is not enough against a raccoon. Use a two-step latch, such as a carabiner clip, a spring-loaded latch or a bolt plus a clip, that requires more than a push or pull to open. Check hinges and gaps in doors, and make sure panels fit tightly so predators cannot get fingers or snouts under or around them. Raccoons are especially persistent, so use a latch that requires opposable thumbs and a bit of thinking to open.

Close the Coop Every Night

The best predator protection is a closed coop at night. Hens put themselves to bed at dusk, so a regular routine of closing the pop door after they go in prevents most nighttime losses. If you cannot be home at dusk, consider an automatic door with a timer or light sensor, but check it regularly, since batteries and mechanisms can fail. Count your birds when you close up, and check for signs of trouble.

Reduce Attractants

• Pick up feed at night and store it in sealed metal bins.
• Collect eggs daily.
• Clean up spilled feed and clear brush near the coop where predators can hide.
• Keep waste and compost away from the coop.
• Control rats, since they attract larger predators.

Read the Signs

If you lose a bird, the evidence can suggest the culprit, although signs can be ambiguous. Missing birds with feathers scattered may point to a fox or hawk. A bird killed and mostly left behind, with the crop eaten out, may suggest a raccoon. A pile of dead birds with little eaten sometimes indicates a weasel or mink. Tracks in mud and trail camera footage can help. If you identify the animal, you can reinforce the relevant weakness.

Guard Animals and Other Tools

Some keepers use livestock guardian dogs, geese or other guard animals, with mixed results. Motion lights and other deterrents can help temporarily, but predators adapt. Nothing replaces a solid structure. If you have repeated problems with a persistent animal, contact your local wildlife agency or a licensed trapper, since laws vary and some methods are regulated.

Mistakes That Cost Birds

• Relying on chicken wire. It stops chickens, not predators.
• Skipping the apron. Diggers will find the gap.
• Forgetting to close up. One missed night is all it takes.
• Weak latches. Raccoons open simple ones.
• Open tops. Hawks and owls strike from above.
• Not checking regularly. Inspect for holes, rot and loose wire.
