Security for Chicken Coops: Tips for Predator-Proofing and Protecting Your Backyard Flock

Security for Chicken Coops: Tips for Predator-Proofing and Protecting Your Backyard Flock

This post is in partnership with 3-IN-ONE® Lock Dry Lube. All thoughts and words are my own.

Whether you live in the city or out in the country, predators are always a concern if you have a flock of backyard chickens.

Raccoons, foxes, coyotes, weasels, owls, hawks, and even neighborhood dogs have been known to attack chickens at night or in plain daylight, especially if they free-range and you’re not nearby to deter unwanted visitors.

By their domestic nature, hens are easy prey: They have few survival skills, rarely take flight, and tend to flock together so they’re easier to target in one fell swoop.

I’ve raised chickens for seven years and learned a lot in that time, the most important lesson being security for chicken coops. In our previous home in the city, we frequently dealt with raccoons, skunks, and opossums passing through our yard.

Raccoons are notorious for preying on backyard chickens

(Some of you may remember the heartbreak of one of our original hens being killed by a raccoon; another was injured in a separate incident but luckily survived.)

In our current home in a semi-rural neighborhood, we’ve found suspicious animal prints around our coop in the morning, and seen owls roosting in our neighbor’s tree.

Though we may not like it, predators are a fact of homesteading life. But there are several security measures chicken-keepers can take to outsmart them, and they should all be considered if you plan to raise a flock or upgrade your chickens’ housing.

Free-ranging chickens

Building (or Reinforcing) a Bomber Chicken Coop

Use Hardware Cloth, Not Chicken Wire
Many new chicken-keepers mistakenly buy chicken wire when building their coops because, well, it’s right there in the name and it seems to make sense. But chicken wire (a hexagonal-shaped welded wire that’s also called poultry netting) is not a secure material for enclosing coops and runs.

It’s a relatively weak mesh that can be ripped apart or gnawed open, and the openings are large enough for raccoon hands or bobcat paws to reach through and snag chickens. Not to mention, mice and rats can easily squeeze through chicken wire in search of spilled feed and food scraps.

A better choice for enclosing coops and runs is 1/2-inch heavy-gauge hardware cloth or 1/2-inch welded wire mesh (typically used for livestock fencing). The mesh can be used for the walls, windows, vents, and doors, and should be attached to the wood framing with washers and screws, or heavy-duty fencing staples.

Secure the Floor of Coops and Runs
Standalone coops should have solid wooden floors to prevent predators from gaining access from below, and be elevated to keep the wood from rotting. (Old pallets work well for this, as do railroad ties, cinder blocks, or paving stones.)

If your coop is attached to an enclosed run, cover the floor of the run with hardware cloth, bring it up the sides a few inches, and attach it to the frame. Pile on dirt, sand, straw, or whatever medium you prefer inside the run, and your flock has a safe space to roam without worry of predators digging under the run.

For large runs where covering the floor isn’t feasible or economical, create a hardware cloth “skirt” or apron. Bury the hardware cloth a few inches around the outside perimeter of the run and extend it at least 18 inches away from the sides.

If you have grass growing around your run, you can simply mow it short, secure the hardware cloth to the ground with landscape staples, and let the grass grow through the mesh.

The skirt prevents predators from digging their way into the run; once they hit the hardware cloth barrier a few times, they’ll give up and move on.

Deter Predators From Above, Too
In areas where hawks and owls are prevalent, it’s a good idea to secure an open chicken run from above as well. Simple bird netting or even a more elaborate pergola-style roof will prevent aerial attacks and keep birds of prey (as well as wild birds that may spread disease) out of the run.

If you have trouble with predators that can scale a fence or wall, install a roof made from welded wire, or construct wooden slats overhead.

Don’t Forget to Defend Against Larger Predators
Do you live in an area where bears are known to roam? If so, no amount of hardware cloth or padlocks can protect your flock from a hungry bear that can demolish wood and wire structures with ease. (This is especially true of prefabricated coops, which usually don’t have a chance of surviving a bear’s impressive strength.)

Protect your backyard chickens against bears and other predators

Strive to build your chicken coop as solidly as you would your own house, and install an electric fence or electric wire around your coop and run.

Remove any source of temptation (like trash, pet bowls, and other food stores) from your yard, or stash them in bear-resistant containers away from your coop.

Lock Doors and Windows at Night
Barrel bolts aren’t enough to keep deft little raccoon hands from gaining access into your coop. I have heard stories of their nimble fingers undoing multiple barrel bolts and other simple one-step locks! (Hey, they have all night to work on them…)

Personally, I only use them on interior doors to the nesting boxes and storage area.

On the exterior, I have gate latches and slide bolts on all of my doors and further secure them with carabiners (especially on the upper locks, which are more out of reach of critters). Spring links and quick links also work, but always make sure your quick links are properly tightened.

Even if you already have a barrel bolt on your door and haven’t run into any problems yet, I still recommend adding a second lock to the door. It only takes a few minutes and will turn your coop into Fort Knox.

If you need to thwart human predators (sadly, it happens — I will never understand what kind of person tries to steal chickens) or just want more peace of mind when you’re gone all day, padlocks are a better option.

Weather-resistant padlocks will offer the best performance in the long run, but any lock left around dusty chickens and out in the elements will start to get sticky (which means you will more likely be lazy about locking them each day).

Rather than replacing all of my locks when this happens, I like to use 3-IN-ONE® Lock Dry Lube to unstick them. A single can lasts a very long time, and can be used for other locks around the house, including door locks, bike locks, car door locks, and even the padlocks I put on my cooler when I camp in bear country. (I know, that last one sounds crazy, right?)

3-IN-ONE Lock Dry Lube helps loosen stuck locks

3-IN-ONE® Lock Dry Lube goes on as a liquid but dries to the touch in just a few minutes, so there’s no messy drips to deal with. It lubricates and loosens stuck locks and leaves a clear film that protects against corrosion.

And most importantly in outside applications, the formula doesn’t attract dirt (which can make locks gummy over time).

Staying Vigilant

Don’t Wait Until Dark
If predators know there’s a potential meal to be had, they’re apt to linger until the last light. Round up your hens well before sundown and make sure they’re safely confined to their coop while there’s still some light left. (My own hens start roosting about half an hour before sunset.)

Hens roosing in their coop

In the same vein, let your flock out well after sunrise so they don’t run into predators that lurk at dawn.

Do a Head Count
Make sure all of your hens are accounted for when you lock them up for the night. Visually sweep the coop and run (with a flashlight, if necessary) to ensure no stragglers wandered in during the day (like feral cats or opossums, which has happened to me before!).

Opossums can find their way into your coop or run

It’s also not uncommon for people to accidentally lock up a neighbor’s cat with their chickens, not realizing the cat was still inside.

Know Your Flock’s Distress Call
As a chicken-keeper, you should familiarize yourself with your flock’s normal behavior and sounds.

Learn to differentiate between their happy clucks, everyday squawks, and enthusiastic “egg song,” as I like to call it, from their frantic distress calls that warn of danger and predators.

Hens free-ranging in the backyard

While you can never fully protect your flock when they’re free-ranging, try to supervise them if you can, or be close enough that you can hear them and chase off predators when needed.

Inspect Your Coop and Run Regularly
Always check your coop and run for signs of damage, wear and tear, or attempted entry by predators. Reinforce or replace any component as needed to keep your structure secure. Even the most well-built coop and run can be infiltrated if a predator has enough time to weaken access points over a long period.

Most importantly, don’t overlook the small stuff. While most of our efforts may be focused on defending against predators like raccoons and hawks, mice and rats (and their droppings) can also pose a serious problem to a flock.

Seal off any gaps or small holes as soon as you find them, and discourage rodents from taking up residence in the first place by collecting eggs daily, storing feed properly, and cleaning up spills or scraps at the end of the day.

Collect all eggs right away to deter predators and rodents

    what can I use on the bottom of a coop and run so chickens will not dig holes no wire as they will scratch and hurt their feet.
    I was thinking about the artificial green turf to lay down but will it makes chickens sick if they peck at it. I have seen posts that people use it in nesting boxes.
    What do you suggest?

      I missed the comment just below yours where the person recommended not putting wire at the bottom of the coop, but I’ve had hardware cloth covering the bottom of mine for the past 11 years and never had a chicken hurt her feet or prevent her from scratching, dust bathing, etc. So your mileage may vary. Currently I use 6 inches of wood pellets as my coop floor and it’s my favorite material so far (I’ve also tried sand and straw in years past).

    Dont ever put wire at the bottom on the coop or run. Chickens scratch, dig, make bowls to dust themselves and the will hurt their feet and prevent them from doing these things even if you cover with dirt. Put a perimeter predator apron around the outside of the run/coop. Look it up.

    Very thorough article about an important topic for future or current backyard chicken keepers. We had to learn a lot of these lessons “the hard way” sadly. The wisdom and pointers in this article will hopefully help someone preemptively. The only piece I would add is about the photosensitive automatic coop door (just like the other commenter mentioned). They are worth the price. We still “head count” our chickens every night and check that all parts of the coop/run are secure as designed, but now if we’re not home at exactly sunset, we don’t fret.

      I agree, and that automatic pop door is something we’re going to incorporate when we move our coop and build a new run for it. It’s a simple and inexpensive solution that benefits everyone!

    Found your site after searching for other people who had survived the cherry tomato plant invasion (your article from 2011?). The compost pile was ground zero a few years back.
    Good tips on chicken coops. I built one for my wife’s mom, and am still getting egg dividends. Your setup looks sweet. Ours is overconstructed like a bomb shelter against Florida hurricanes, but I learned how to roof in the process. For anyone reading, the photosensitive automatic slide doors for coop entrances really helped her mom keep her freedom and not miss out on evenings making sure her girls were closed up in the coop.

      We have lots of “undigested” tomato and squash seeds from our compost pile too. They’re prolific! 🙂
