What Is Chicken Wire? | Simple Fencing for Poultry & Gardens

If you’ve ever seen a chicken coop or a garden fence that looks like a diamond-patterned net made of thin, bendable wire, you were looking at chicken wire. It’s one of the oldest and most common fencing materials, and knowing exactly what it is—and what it isn’t good for—makes the difference between a secure enclosure and a disappointing one. This article covers what chicken wire is made of, what it does well, where it falls short, and how to choose the right kind for your project.

What Exactly Is Chicken Wire Made Of?

Chicken wire, also called poultry netting or hex net, is a type of wire mesh woven into a hexagonal pattern. The most common material is thin galvanized steel wire, which resists rust and weathering. You’ll also find stainless steel versions that offer more resistance to acids and corrosion, and PVC-coated varieties available in colors such as green, black, or gray. The wire gauge typically ranges from 19 to 22, with thinner wire being more flexible and easier to cut but less strong. Common mesh openings are ½ inch, 1 inch, and 2 inches across the hexagon, with 1-inch being the standard choice for most poultry and garden uses.

When you’re ready to buy, it helps to know exactly what you need. Our roundup of the best chicken wire options breaks down the top materials, gauges, and brands for different projects so you pick the right one the first time.

How Is Chicken Wire Made and What Does It Look Like?

The mesh is created by weaving thin wires together in a machine that twists them at each intersection to form a continuous hexagonal sheet. The twisting method can be straight, reverse, or double/triple twist, which affects the stability of the mesh. The finished product is lightweight, very flexible, and easily cut with standard wire cutters. This flexibility makes it easy to shape around corners, trees, or uneven ground—one reason it remains popular after nearly 200 years.

What Is Chicken Wire Used For?

The original use was confining chickens, and it’s still the go-to for that job. But its uses extend into several other areas:

• Poultry and small-animal enclosures: A barrier around a chicken coop, rabbit hutch, or run to keep the animals inside.
• Garden fencing: Protects plants, vegetables, and flower beds from larger animals like deer and dogs, and can support climbing plants.
• Insulation backing: Plasterers and insulators use it as a matrix to hold insulation cements or stucco in place on walls.
• Light construction and crafts: From sculpture bases to homemade trellises, chicken wire’s flexibility makes it useful in many DIY projects.

Important limitation: Because it is thin and flexible, chicken wire is excellent at keeping your animals in, but it is not strong enough to keep determined predators out. Raccoons, foxes, and dogs can bend or tear through it without much effort. For predator-proof fencing, you need heavier welded wire or hardware cloth.

Common Mistakes People Make With Chicken Wire

The four biggest errors are easy to avoid once you know them:

1. Using it as predator-proof fencing. As noted above, chicken wire stops chickens, not raccoons. Always pair it with a stronger barrier where predators are a concern.
2. Confusing it with stiffer products. Chicken wire is not the same as welded wire fencing or hardware cloth, both of which have much stronger, rigid joints. Welded wire is better for long-life, high-security enclosures.
3. Assuming one size fits all projects. A 2-inch mesh is fine for adult chickens but won’t stop baby chicks or rabbits. Choose the mesh opening based on what you’re containing or protecting.
4. Expecting standard galvanized chicken wire to last decades. Galvanized coating resists rust, but it can wear off over time, especially in contact with soil or acidic wood. PVC-coated or stainless steel versions last longer in wet conditions.

A Brief History

Chicken wire was invented in 1844 by Charles Barnard, an English ironmonger from Norwich. The material and the term have been in continuous use since the mid-19th century, making it one of the most enduring fencing designs in modern history. Its simple, effective design explains why it’s still a staple on farms and in gardens today.
