6 Chicken Coop Tarp Draft Protection That Old Farmers Swear By
Learn 6 farmer-proven tarp methods to protect your flock from dangerous drafts. These time-tested techniques ensure a warmer, healthier chicken coop.
That biting north wind finds every crack and seam in a chicken coop, and a drafty coop is a recipe for sick birds and frostbitten combs. Proper draft protection isn’t about making the coop airtight; it’s about controlling airflow to keep your flock healthy through the coldest months. For a fast, effective, and affordable solution, nothing beats a good tarp.

Why Tarps Beat Plywood for Winter Coop Drafts
When a cold snap is coming, you don’t have time to be a master carpenter. Tarps go up fast with just a handful of screws or staples, providing instant protection where you need it most. Plywood is a permanent, heavy solution that requires cutting, fitting, and more effort to install and remove.
The biggest advantage of a tarp is its temporary nature. You can block the windward side of the coop in winter and easily roll it up or take it down come spring to restore ventilation. Plywood walls block that crucial summer cross-breeze and can trap moisture year-round, creating a damp environment that’s far worse for chickens than the cold itself.
Tarps are also forgiving. A coop settles, wood warps, and gaps appear. A flexible tarp can cover those imperfections easily, while a rigid piece of plywood needs to be precisely cut to be effective. For a quick, reversible, and budget-friendly fix, tarps are the clear winner.
Heavy-Duty Canvas Tarps: The Breathable Choice
Canvas is the old-school solution for a reason. Its greatest strength is breathability. While it blocks wind effectively, the woven cotton fabric allows moisture vapor to escape, which is critical for preventing condensation and frost buildup inside the coop.
A damp, sealed-up coop is a breeding ground for respiratory illness and frostbite on combs and wattles. A treated canvas tarp strikes the perfect balance, stopping the biting wind while letting the moisture from the birds’ breath and droppings get out. They are also quiet, unlike a poly tarp that flaps and cracks loudly in the wind, which can stress the flock.
The tradeoff is weight and water resistance. Untreated canvas will get saturated and heavy, so look for one that is water-repellent or wax-treated. They cost more than a basic poly tarp, but their durability and breathability make them a sound investment for the long haul, especially in climates with damp, cold winters.
Clear Vinyl Tarps for Sunlight and Warmth
Covering the open, wire-mesh side of a run with a clear tarp is one of the best things you can do for your flock’s winter morale. It blocks the wind and snow completely while letting in precious sunlight. This creates a small greenhouse effect, passively warming the space and giving the birds a comfortable, bright area to use on sunny winter days.
This influx of natural light is also important for egg production and Vitamin D synthesis. A dark, gloomy coop all winter can stress your birds and slow down laying. A clear vinyl panel, even if it just covers the run, makes a world of difference for their well-being.
Be aware that clear vinyl is not as tough as other options. It can become brittle and crack in deep-freeze temperatures and is more susceptible to tearing than a heavy canvas or PVC tarp. Use them strategically on the sun-facing, less windy side of the coop or run for maximum benefit and lifespan.
Reversible Poly Tarps: The All-Purpose Staple
The common blue, brown, or green polyethylene tarp is the affordable workhorse of the farm. It’s cheap, lightweight, and completely waterproof, making it a go-to for quick fixes. If you have an unexpected draft or a leaky spot on the roof, a poly tarp is the fastest way to solve the problem.
Many of these tarps are reversible, often with a silver side and a darker side. While the effect is modest, you can face the dark side out in winter to absorb a bit more solar heat and face the silver side out in summer to reflect it. It’s a small advantage, but every little bit helps.
The major downside is that poly tarps are 100% non-breathable. If you use them to block a large wall, you must ensure you have excellent high ventilation (vents near the roofline) to let moisture escape. They are also notoriously noisy, and the constant flapping in a high wind can be a source of stress for your chickens.
Insulated Tarps for Extreme Northern Climates
For those in truly cold regions where temperatures consistently drop well below zero, an insulated tarp is a serious upgrade. These are essentially durable, water-resistant blankets filled with insulating foam or poly-fill, complete with grommets for easy hanging. They offer a real R-value, helping to hold the birds’ collective body heat inside the coop.
Think of it as wrapping your coop in a winter coat. An insulated tarp is most effective when used on the windward wall or the northern-facing side of the coop, where the most heat is lost. It dramatically reduces the temperature differential, making the coop more stable and comfortable without the need for risky heat lamps.
These are a specialized tool, not an everyday solution. They are heavier, more expensive, and completely block light. Using one means you are fully committed to managing ventilation separately, as they create a very tight seal. But in a blizzard or a polar vortex, they can be the difference between a comfortable flock and a dangerously cold one.
PVC Coated Tarps: Unbeatable Wind Protection
When your primary enemy is relentless, powerful wind, a PVC (polyvinyl chloride) coated tarp is your best defense. These are the same heavy-duty, rubbery tarps used on commercial trucks and for industrial coverings. They are incredibly tough, tear-resistant, and completely unfazed by high winds.
A standard poly tarp will shred itself in a season of constant wind exposure, but a PVC tarp will last for years. The thick, vinyl coating makes it 100% waterproof and creates an impenetrable barrier against the wind. If your coop is in an exposed field with no natural windbreak, this is the material you want.
Like insulated and poly tarps, PVC is a total vapor barrier. Ventilation is not optional; it’s mandatory. You must have high vents, far from where the birds roost, to allow ammonia and moisture to escape. The cost and weight are higher, but for sheer durability and wind-blocking power, nothing else comes close.
Hay Tarps: Covering Large Coops and Runs
If you have a large, barn-style coop or want to cover an entire chicken run, a standard-sized tarp won’t cut it. This is where hay tarps come in. Designed to cover massive haystacks, they are built for huge dimensions and long-term UV exposure, making them perfect for large-scale protection.
These tarps are made from heavy-duty, UV-treated polyethylene and come in sizes that can easily blanket a 20×30 foot run. Covering the top and the windward side of a run can create a large, usable winter space for your flock, keeping the ground dry and free of snow. This prevents the muddy, icy mess that often keeps chickens cooped up for months.
Because of their size, securing them properly is non-negotiable; a huge tarp can act like a sail in the wind. They are an investment, but for a large flock, the benefit of creating a dry, protected, and expansive winter habitat is enormous. It’s about protecting the entire living space, not just the sleeping quarters.
Securing Tarps with Battens and Grommets
A tarp is only as good as its installation. Simply putting a few screws through the grommets is asking for trouble. The first big gust of wind will pull the grommets right out, leaving you with a shredded, flapping mess.
The best method is to use wood battens. A batten is simply a thin strip of wood, like a 1×2 or a 1×3. You sandwich the edge of the tarp between the batten and the coop wall and then drive screws through the batten, the tarp, and into the coop’s framing. This distributes the pressure along the entire length of the wood instead of concentrating it on a few small grommets.
Craft with ease using these 100 bamboo sticks, perfect for model building and DIY projects. They're easy to cut, drill, and bend, offering strong support for kites, doll houses, and more.
For extra security, especially at the corners, use screws with large fender washers through the grommets. The washer spreads the load and prevents the screw head from tearing through the grommet. A properly secured tarp should be taut and silent, not loose and flapping. Taking an extra 15 minutes to add battens will save you from having to go out in a storm to fix a failed tarp.
Ultimately, the best tarp is the one that solves your specific problem—be it wind, moisture, or extreme cold. Remember that the goal is to block drafts at roost level while allowing moisture to escape through high vents. A dry, draft-free coop is the foundation of a healthy winter flock.
