How to House Your Pigs: Sheds Fencing and Space Requirements
Before you bring home a single pig, you need somewhere to put it. And not just “a spot in the yard.” Pigs need real shelter, real space, and real fencing. Get any of these wrong and you will have a very bad time.
Chapter 3 of Backyard Farming: Raising Pigs by Kim Pezza breaks down everything you need to know about housing your pigs. There is a lot to cover, so let’s get into it.
How Much Space Do Pigs Need?
More than you think.
For a mature pig with access to an outdoor area, plan for 48 to 50 square feet of shed space per pig. If your pigs do not have outdoor access (not ideal, but sometimes reality), you need about 100 square feet per pig indoors.
For the outdoor area itself, you want at least 200 square feet per pig. Breeding animals need even more, around 400 square feet per animal.
These are minimums. More is always better.
Drainage Matters More Than You Think
Here is something most people overlook: the type of soil on your property changes how much space you need.
Sandy soil drains well, so you can get away with the minimum of 100 square feet per animal in the outdoor area. Clay soil? That stuff holds water and turns into a swamp. With clay, you need 200 to 250 square feet per animal at minimum. Some experienced farmers recommend up to 800 square feet per pig to keep things manageable.
Pigs plus mud is fine. Pigs plus standing water and bad drainage is a health problem waiting to happen.
Rotational Grazing
If you have real pasture land, you can run about 10 pigs per acre of good pasture, but you will still need to provide supplemental food. This is important: pigs cannot survive on pasture alone. They are not cattle. They need grain and other nutrients to stay healthy.
Rotating them through different sections of pasture helps keep the ground from turning into a wasteland. It also breaks parasite cycles, which is a big deal for pig health.
The Shed
Here is the good news: pig sheds do not need to be fancy. Pigs sleep close together. They are social animals and they like to pile up, especially in cold weather. So your shed does not need to be huge.
What it does need:
- A dry floor. This is the single most important thing. Wet floors cause foot problems, respiratory issues, and general misery.
- Good ventilation. Fresh air flow is critical for pig health.
- A solid roof. Leaks defeat the purpose of having shelter.
- Good bedding. More on this in a second.
- Non-slip flooring. Pigs on slippery surfaces hurt themselves. Adding wooden batons to the floor gives them traction.
The Bedding Debate: Hay vs Straw
Some people swear by hay. Others say straw only. The author used straw for years and never had a problem with it. Pigs love straw. In winter, they burrow right into it and build themselves little nests. It is actually pretty great to watch.
One nice thing about pigs: they are surprisingly clean animals. They will not go to the bathroom in their shed if they have any choice at all. They pick a separate spot for that. So your bedding stays cleaner than you would expect.
Ventilation: The Balancing Act
You want good air flow, but you do not want drafts. A draft in winter can make pigs sick fast.
How do you know if your pigs are too cold? They huddle together tightly, shiver, and eat more than usual. If you notice your feed bill going up and your pigs piling on top of each other, they are telling you something.
Too warm? They avoid contact with each other, eat less, and start panting. Pigs do not sweat, so they have a hard time cooling down. Heat is actually more dangerous than cold for most pigs.
Types of Housing
You have options here, and the author covers several.
Wooden sheds are better than metal ones. Metal gets extremely hot in summer and cold in winter. Wood insulates naturally and is easier to work with.
Other options that work:
- Calf hutches work well for smaller setups
- Porta-huts are portable and practical
- Old greenhouses can be converted (seriously)
- Mini-barns are a great choice if you can afford them
The author built her own shed: 20 feet by 10 feet with a slanted roof. Nothing fancy. It did the job for years.
Fencing: The Big One
If housing is important, fencing is critical. A loose pig is a problem. A loose pig in your neighbor’s garden is a disaster. And pigs are smart, strong, and determined.
Let’s talk about your options.
Hog Panels
These are the gold standard for pig fencing. They are 16-foot rigid metal panels that you attach to posts. They are strong, reliable, and purpose-built for hogs. If you can afford them, use them.
Wire and Field Fencing
This works if you use thick gauge wire. Thin wire is useless. Pigs will push through it, lean on it, and generally destroy anything flimsy. Go heavy duty or do not bother.
Wooden Fences
These can work, but they need reinforcement. Pigs rub against fences. They lean on them. They test them. A basic wooden fence on its own will not hold up for long.
What Does NOT Work
Chain link fence does not work for pigs. It seems like it should, but pigs will lift it, bend it, and push through it. Do not waste your money.
Electric Fence
Electric wire is great as a training tool. You run a hot wire along the inside of your main fence. Pigs learn quickly. One or two zaps and they respect the boundary.
But electric alone is not enough as your primary fence. Use it as backup and training, not as your only barrier.
The Boar That Jumped
The author shares a story about her boar jumping a temporary fence. Just straight up launched himself over it. Boars in particular are strong and motivated, especially when there is a sow nearby. Do not underestimate them.
Dig Guards
Pigs do not just go through or over fences. They go under them. The solution is a dig guard: a strip of metal buried about 6 inches underground along the fence line. This stops them from rooting their way to freedom.
Fence Maintenance
Build a good fence, and then inspect it regularly. Walk your fence line. Check for weak spots, leaning posts, gaps at the bottom. A fence is only as good as its weakest point, and your pigs will find that weak point before you do.
The Bottom Line
Housing pigs is not complicated, but it does require thought and planning. Get the space right. Get the drainage right. Build a simple, dry, well-ventilated shed. And for the love of everything, build a good fence.
Your pigs will test every boundary you set. That is just what pigs do. Plan for it, and you will be fine.
