Ducks are basically feathered snacks for every carnivore in a five-mile radius. It sounds harsh, but if you've ever walked out to your coop at 6:00 AM only to find nothing but a pile of feathers and a broken heart, you know I’m not exaggerating. Predators like raccoons, foxes, and weasels are clever. They don't just want a meal; they have the dexterity and persistence of a safe-cracker. Building a predator proof duck house isn't just about putting up some plywood and calling it a day. It’s an arms race.
Most people start keeping ducks because they’re hardy. They handle the cold better than chickens and their eggs are rich. But ducks are also incredibly vulnerable because they are heavy, slow, and—frankly—not very bright when it comes to self-preservation. While a chicken might fly up to a high roost, a duck usually just sits there. This makes the structural integrity of their housing the only thing standing between them and a very bad night.
The Hardware Cloth Rule (And Why Chicken Wire is a Lie)
Let’s get one thing straight: chicken wire is for keeping chickens in, not for keeping predators out. If you are using that thin, hexagonal wire, you might as well be using tissue paper. A determined raccoon can pull it apart with its paws, and a fox can bite through it in seconds.
For a truly predator proof duck house, you need 1/2-inch or 1/4-inch galvanized hardware cloth. It’s a pain to work with—it’ll cut your hands if you aren't wearing gloves—but it’s the gold standard. You need to staple it down with heavy-duty fencing staples, not just thin office staples or small nails.
Raccoons are the biggest threat here because they have hands. They will reach through gaps and literally pull a duck apart piece by piece through the wire. By using a small mesh like 1/2-inch hardware cloth, you ensure those tiny, murderous hands can't get inside. It's an investment that saves you from a lot of grief later on.
Digging Deeper: The Hardware Cloth Skirt
Predators don't just go through the door; they go under the walls. Rats, weasels, and foxes are expert diggers. You can build a fortress of a house, but if the floor is just dirt, a predator will just tunnel underneath while you’re asleep.
There are two ways to fix this. First, you can give your house a solid wooden or concrete floor. If you go with wood, make sure it’s thick enough that a persistent gnawer can't get through. But many people prefer the "deep litter" method on a dirt floor. If that's you, you absolutely must install a hardware cloth skirt.

This involves burying the wire at least 12 inches into the ground all around the perimeter of the house. Even better? Flare it outward. When a fox starts digging at the base of the wall, it hits the wire. It doesn't have the logic to step back two feet and start digging there; it just gives up. It’s a simple psychological trick for animals that works incredibly well.
Windows, Vents, and the "Pinky Finger" Test
Ducks produce a massive amount of moisture. If you don’t have ventilation, your ducks will get respiratory issues or frostbite in the winter because the air is too damp. But every vent is an open invitation.
You’ve got to check every single gap in your predator proof duck house. A weasel can fit through any hole the size of a wedding ring. Seriously. If you can stick your pinky finger into a gap, a weasel can get its head through, and if the head fits, the body fits.
Cover every window and vent with that same hardware cloth we talked about. Use screws and washers to secure the wire to the frame of the house. Don't just tack it on the outside; sandwich it between two pieces of wood so it can't be pried off. It sounds like overkill until you realize how strong a hungry coyote actually is.
Locks and Latches: Think Like a Raccoon
If you have a simple sliding bolt or a hook-and-eye latch, a raccoon will figure it out. They are remarkably patient. I’ve seen them slide bolts open in minutes.
You need "two-step" locks. Think carabiners, spring-loaded latches, or padlocks. Anything that requires a bit of dexterity and two distinct movements to open will usually stump a raccoon. It’s annoying for you when you’re trying to carry a bucket of water and open the door at the same time, but it’s the price of safety.

The Nightly Routine vs. Automatic Doors
Even the best predator proof duck house is useless if the door is left open. This is where most "predator attacks" actually happen—human error. You get home late, you forget, or you think "oh, they'll be fine for one night." They won't be.
Automatic coop doors have become a huge trend. They’re great, but they aren't foolproof. Some of the cheaper models can be pried up from the bottom by a clever predator. If you buy one, make sure it has a locking mechanism when closed.
Also, ducks are notorious for not going inside when they're supposed to. Unlike chickens who head to the roost at dusk like clockwork, ducks might decide to stay out on a pond or sit in the middle of the run until it’s pitch black. You still have to do a "head count." Every. Single. Night.
Dealing with Aerial Predators
We spend so much time worrying about things on the ground that we forget about the sky. Hawks and owls are devastating. An owl can snatch a duck in the middle of the night if your house has an open-top run.
If your ducks aren't locked inside a solid building at night, their "day run" needs to be fully enclosed with poultry netting or, ideally, more hardware cloth. Brightly colored tape or hanging CDs can deter hawks during the day, but they aren't a guarantee. A physical barrier is the only thing that works 100% of the time.
Real World Example: The Weasel Massacre
A friend of mine in rural Pennsylvania thought her coop was solid. She had 1-inch chicken wire and a heavy wooden door. One morning, she found all six of her ducks dead. No meat was eaten; they were just killed and left there.

That is the hallmark of a weasel. They kill for sport or out of a predatory reflex. They got in through a small gap where the roof met the wall—a gap she thought was too high and too small for anything to care about. This is why the "pinky finger" rule is the most important thing you’ll read today.
Siting the House for Maximum Safety
Where you put the house matters. Don't put it right up against a fence line where a predator can jump from the fence onto the roof. Keep it in a clear area where you have a good line of sight from your own back door.
Predators hate being out in the open where they feel exposed. By keeping a perimeter of mowed grass around the predator proof duck house, you make it much more intimidating for a fox to approach. They prefer cover. Use that instinct against them.
Actionable Steps for a Secure Setup
If you’re looking at your current setup and feeling a bit worried, don't panic. You can retrofit almost any structure to be safer. Start with the most likely entry points and work your way down.
- Audit your wire: Replace all chicken wire with 19-gauge galvanized hardware cloth.
- Secure the perimeter: If you can't dig a trench, lay hardware cloth flat on the ground extending two feet out from the coop walls and stake it down. Grass will grow through it, hiding it, but it'll stop diggers.
- Upgrade your locks: Toss the simple hooks. Get heavy-duty latches that require a carabiner or a secondary pin to open.
- Seal the gaps: Use expanding foam for insulation if you want, but cover it with wood or metal trim. Predators will chew right through foam.
- Check the roof: Ensure there are no gaps between the rafters and the top of the walls. Use bird blocks or hardware cloth to seal those triangular openings.
- Add motion lights: Solar-powered motion sensor lights won't stop a hungry predator, but they can act as a deterrent and, more importantly, alert you that something is moving outside.
- Listen to your birds: If you hear your ducks making a "hissing" sound or a rhythmic, panicked quack in the night, get out there with a flashlight. They know when something is watching them.
Building a predator proof duck house is about layers of defense. No single thing is perfect, but when you combine buried wire, solid locks, and tiny mesh, you make your backyard a very frustrating place for a predator. Most will eventually move on to an easier target. Keep your birds locked up tight, stay vigilant about maintenance, and you'll avoid the heartbreak of a preventable loss.
