9 Proven Ways to Keep Snakes Away From Your Chickens
In short: how to keep snakes away from your poultry: Seal gaps with ¼-inch hardware cloth, bury a 12-inch skirt, elevate nesting boxes 18 inches, remove brush 20 feet out, and collect eggs twice daily.
Part of our guide on containment solutions for chickens
Snakes follow rodents and egg scent, so most fixes fail because they target the snake instead of what brought it.
| Mesh size needed | ¼ inch or smaller |
|---|---|
| Burial depth | 12 inches minimum |
| Clear zone radius | 20 feet from coop |
| Egg collection | Twice daily |
| Coop elevation | 18-24 inches |
| Most common species | Rat snakes, black snakes, racers |
The short version
- Hardware cloth with ¼-inch mesh stops snakes; chicken wire does not
- Elevating coops 18-24 inches forces snakes into the open where chickens spot them
- Clearing cover within 20 feet removes hunting paths snakes use
- Collecting eggs twice daily eliminates the scent trail that draws egg-eaters
- Adult chickens kill small snakes but can't defend eggs or chicks
What You Need
Most snake exclusion uses materials you already own or can pick up in one hardware store trip. The job takes a weekend for a typical backyard coop, longer if you're retrofitting an older setup with gaps.
You'll spend $80 to $150 depending on coop size. That's mostly hardware cloth, which runs $1.20 to $2 per square foot for galvanized ¼-inch mesh. Cheaper rolls use thinner wire that snakes push through.
- Hardware cloth: ¼-inch mesh, galvanized, enough to cover all vents and bury a 12-inch skirt around the perimeter
- Wire cutters or tin snips: for cutting hardware cloth to size
- Staple gun with ½-inch staples: for attaching mesh to wood framing
- Shovel or trenching spade: for burying the barrier
- Work gloves: hardware cloth edges are sharp and will cut bare hands
- Rake and pruning shears: for clearing vegetation and debris

How to Keep Snakes Away From Your Poultry
how to keep snakes away from your poultry. Use barriers, remove attractants, and deny cover. Do the simple fixes first: seal gaps, pick up eggs, remove brush, and stop spilled feed. The rest reduces risk further.
Start with hardware cloth. Cover vents, windows, and any gap larger than ¼ inch with galvanized mesh. Replace rusted or torn sections. Snakes test weak spots when they smell eggs or rodents. Before you commit to anything, it is worth looking at differences between chicken and duck feet.
Create a buried skirt. Dig a trench 12 inches deep and 6 inches out. Bend the mesh into an L: 12 inches down and 6 inches out. Backfill and tamp the soil so snakes can't burrow under the walls.
Raise the coop. Elevate the floor 18 to 24 inches. Chickens spot a snake crossing bare ground and will mob small ones. Wrap posts with a 12-inch band of smooth metal or PVC that spins to stop climbing.
Remove cover within 20 feet. Cut brush and mow to 3 inches or less. Store firewood at least 30 feet away on pallets. A woodpile against the coop wall invites snakes. There is more on chickens and ticks in a separate guide.
Collect eggs twice a day, morning and evening. Eggs can smell like food from 50 yards downwind. Broken eggs draw snakes within hours. Clean or replace nesting material soaked with yolk.
Control rodents and spilled feed. Use treadle feeders or bring feeders inside at dusk. Spilled grain draws mice. One breeding pair of mice can produce 60 offspring in a season and sustain many snakes.
Seal every crack over ¼ inch. Walk the coop with a flashlight. Fill small gaps with exterior caulk. Patch larger holes with hardware cloth stapled every 3 inches. Foam alone is not enough. We cover signs of predator damage on chickens in its own article.
Add a smooth apron. Lay a 2-foot-wide apron of sheet metal, rubber matting, or landscaping fabric around the coop. Pin it every 18 inches. The apron stops surface movement; the buried skirt blocks digging.
Keep nesting boxes tight and elevated. Mount boxes at least 18 inches off the floor with solid backs. Check joins weekly for splitting or warping. Replace any weakened box immediately.
1. Install ¼-Inch Hardware Cloth on All Openings
Cover every vent, window, and gap larger than ¼ inch with galvanized hardware cloth. Corn snakes and young rat snakes flatten to ½ inch and will squeeze through bigger openings. We cover valheim chicken feeding guide in its own article.
Staple the mesh to the inside of each frame with a staple every 3 inches. Check the join where wall meets floor; wood settles and gaps form there.
Replace sections showing rust or torn wire. Snakes probe weak spots when they smell eggs or chicks.
2. Bury a 12-Inch Hardware Cloth Skirt Around the Perimeter
Dig a trench 12 inches deep and 6 inches out from the walls. Bend hardware cloth into an L: 12 inches down, 6 inches out. This stops burrowing.
Backfill and tamp the soil so the skirt stays upright. Snakes that hit the barrier move on.
Extend the skirt around an attached run. An open run without a barrier attracts rodents and then snakes.
3. Elevate the Coop 18 to 24 Inches Off the Ground
Raise the coop on posts or blocks 18 to 24 inches. Chickens see snakes crossing bare ground and will mob small snakes.
Wrap each post with a 12-inch band of sheet metal or a PVC collar that can spin. Snakes cannot grip a smooth spinning surface.
Clear the area under the coop. Junk under the floor becomes prime snake habitat.
4. Remove Cover Within 20 Feet of the Coop
Cut brush, tall grass, and ground debris to create a bare buffer of 20 feet. Snakes use cover to move unseen.
Mow or rake the zone down to 3 inches or less so hawks can see snakes. Most snakes will detour.
Store firewood and lumber 30 feet away on pallets. A woodpile next to the coop is snake magnet.
5. Collect Eggs Twice a Day, Morning and Evening
Collect eggs twice daily. Egg scent carries 50 yards downwind. The longer eggs sit, the stronger the trail.
Clean up cracked eggs immediately and replace soaked nesting material. A rat snake that finds eggs will return every few days.
This protects eggs and reduces repeat visits from egg-eating snakes.
6. Control Rodents and Remove Spilled Feed Daily
Switch to a treadle feeder or bring feeders inside at dusk. Spilled grain attracts mice that then attract snakes.
Set snap traps in rafters and along exterior walls. One breeding pair of mice can produce 60 offspring in a season.
Remove spilled feed every day and store grain in sealed metal containers.
7. Seal Gaps in the Coop Structure Larger Than ¼ Inch
Inspect the coop with a flashlight and mark every crack. Fill small gaps with exterior caulk or expanding foam.
Cover larger holes with hardware cloth patches and staple every 3 inches. Foam alone will not stop determined snakes.
Check where the roofline meets walls. A 2-inch gap under the eave is a snake highway.
8. Use a Smooth Apron Around the Coop Base
Lay a 2-foot-wide apron of smooth sheet metal or rubber matting around the coop. Pin it with landscape staples every 18 inches.
The smooth surface gives no cover and stops rodents from burrowing near the walls.
Pair the apron with the buried skirt for a continuous barrier.
9. Keep Nesting Boxes Elevated and Tight to the Wall
Mount nesting boxes at least 18 inches off the floor. Use solid backs and sides so snakes cannot enter from behind.
Avoid shelves or ledges a snake can use to climb. Check boxes weekly for splitting or warping.
Replace any box that's weakened. A snake will widen a small crack over repeated visits.
What to Put Around the Outside of the Coop for Snake Deterrent
Physical barriers work. Scent deterrents do not, despite what the labels claim. Snakes rely on heat sensing and vibration more than smell, so products with sulfur, naphthalene, or essential oils wash away in the first rain and accomplish nothing.
The only repellent product with any research support is Snake-A-Way, which combines sulfur and naphthalene. Even then, results are mixed. It may deter garter snakes for a few days in dry weather, but rat snakes and black snakes cross treated areas without hesitation.
Is Snake Stopper safe for chickens? The active ingredients are generally low-toxicity to birds, but chickens will peck at granules on the ground, and ingestion can cause respiratory irritation. It's not worth the risk when hardware cloth actually works.
Skip the mothballs, cinnamon oil, clove oil, and vinegar. You'll find hundreds of testimonials online, but controlled tests show no consistent effect. Save the money and put it toward hardware cloth.
Keeping Rattlesnakes and Venomous Species Away From Chickens
The same barriers that stop rat snakes stop rattlesnakes, copperheads, and cottonmouths. Venomous species don't have special entry skills; they just carry more risk when they get in.
Rattlesnakes are ambush hunters that wait for rodents near cover. Clear the buffer zone to 30 feet instead of 20 if you're in rattlesnake country. A snake coiled in tall grass 6 feet from the coop is a danger to you, not just the chickens.
Free-ranging chickens will mob a rattlesnake but usually from a cautious distance. The snake strikes, the chickens jump back, and the standoff continues until the snake leaves. Losses are rare unless a hen steps on a coiled snake by accident.
If you find a venomous snake inside the coop, close the hatch and call a licensed snake removal service. Don't try to corner it with a shovel. A stressed copperhead in a confined space will strike at anything that moves.
| Species | Threat to Chickens | Threat to Keeper | Typical Reason for Visit |
|---|---|---|---|
| Rat snake / black snake | Low (adult birds), high (eggs) | None | Hunting rodents or eggs |
| Rattlesnake | Low (adult birds), moderate (chicks) | High | Hunting rodents in cover |
| Copperhead | Low | Moderate | Hunting rodents or sheltering |
| Garter snake | None | None | Hunting insects or frogs |
How to Get Rid of a Snake Already Inside the Coop
If a snake is inside the coop now, open the main door and prop an exit ramp from the ground to the threshold. Step back at least 20 feet and watch. Most snakes will leave when the area is active and exposed.
For a snake in a nesting box, use a long-handled rake or hoe to nudge it toward the exit. Keep the tool between you and the snake. Even nonvenomous species bite when cornered and leave jagged wounds from recurved teeth.
If the snake has a visible bulge from a recent meal, wait an hour. A digesting snake moves slowly and is less likely to flee far before hiding.
Do not try to handle a snake you cannot positively identify. For venomous or uncertain cases, call a local wildlife removal service. Typical response costs run $75 to $150. That cost is far less than a medical emergency after a bite.
If you catch a nonvenomous snake, sweep it into a plastic bin with a broom, snap the lid on, and release it at least 500 yards from your property in heavy cover. Snakes have a homing range near 300 yards, so move it well beyond that.
After removal, find and seal the entry point the same day. A snake that has a successful feed or nesting raid will return until you block its access.
Do Chickens Eat Snakes or Protect Themselves
Adult chickens will kill and eat small snakes up to about 3 feet long. Larger, bold breeds like Rhode Island Reds and Australorps attack more often than docile breeds such as Silkies.
Hens mob a snake by darting in to peck and then jumping back. The repeated strikes exhaust and injure the snake until it dies. Chickens then tear it apart and eat it.
Roosters are more aggressive and can kill bigger snakes. A mature rooster can sometimes kill a 4-foot black snake, but fights cause injuries to the bird.
Chicks and juvenile birds cannot defend themselves. Rat snakes and bull snakes will swallow chicks whole if they enter brooder space. Use ¼-inch hardware cloth on brooders, not window screen.
Eggs offer no defense. A snake inside the coop at night can eat a dozen eggs before morning. Rat snakes that find eggs often return every 3 to 5 days to raid the same coop.
Common Mistakes That Let Snakes In
Most snake intrusions happen because keepers focus on the wrong things or leave a single gap that bypasses all the other work. A coop is only as secure as its weakest point.
- Using chicken wire instead of hardware cloth: Chicken wire stops chickens, not snakes. A ¼-inch gap is all a young snake needs.
- Clearing brush but leaving tall grass: Grass over 6 inches tall is enough cover for a snake to cross unnoticed. Mow short or lay gravel.
- Elevating the coop but not wrapping the posts: A snake climbs a bare wooden post as easily as a tree. Add a smooth spinning collar.
- Collecting eggs once a day: Morning collection leaves eggs sitting all afternoon, which is when most snakes hunt. Collect twice.
- Sealing the walls but ignoring the roof: Snakes climb. Check where the roof meets the walls, and cover any eave gaps with hardware cloth.
- Using repellent sprays instead of barriers: Repellents wash away, and snakes cross treated areas anyway. Spend the money on mesh.
- Leaving feed out overnight: Spilled feed brings rodents, rodents bring snakes. Use a treadle feeder or bring feeders in at dusk.
- Assuming one snake means one problem: If you catch one snake, assume there are more. Snakes overlap in territory and follow the same scent trails.
Questions people still ask
Will a snake come back after I remove it from the coop?
Yes, if you don't seal the entry point. Snakes have strong spatial memory for successful hunting sites and will return within 3 to 7 days if the opening remains. Inspect the coop the same day you remove the snake and seal any gaps. A snake removed but not excluded is just a delayed problem.
Can I use fake eggs to poison or trap snakes?
Fake eggs don't work as bait because snakes detect eggs by scent, not sight. There is no legal snake poison sold in the US for backyard use, and homemade toxic eggs are dangerous to your chickens, pets, and wildlife. Focus on exclusion and rodent control instead. A snake with no food source leaves on its own.
How do I know if a snake is venomous before I remove it?
In the US, venomous snakes have triangular heads, vertical pupils, and a single row of scales on the underside of the tail past the vent. Non-venomous snakes have round pupils, narrow heads, and a double row of scales. If you're uncertain, treat it as venomous and call a professional. Don't rely on color alone: rat snakes and copperheads can look similar at a glance.
Will guinea fowl keep snakes away from my chickens?
Guinea fowl raise an alarm when they spot a snake, which can alert you and spook the snake into leaving. They do not actively kill or chase snakes the way chickens sometimes do. They're useful as a noisy early warning system but not a replacement for physical barriers. A determined rat snake will ignore them and raid nests anyway.
What time of year are snakes most likely to get into the coop?
Snake activity peaks in late spring and summer when they hunt most actively. May through August brings the highest intrusion rates in most US regions. Fall brings a second smaller spike as snakes search for rodents before hibernation. Winter intrusions are rare but possible in warmer climates or if the coop provides heat.
