What a Chicken Run Is and Why You Need One
A chicken run is an enclosed outdoor pen that lets your chickens scratch, peck, and forage while protecting them from predators like foxes, hawks, and raccoons. Unlike a fixed coop, a run is often portable or semi-portable, giving your birds access to fresh ground and grass without the risk of them wandering into your garden or a neighbor's yard.
The run works alongside your coop: the coop is where chickens roost and lay eggs at night, while the run is where they spend their daytime hours. A well-built run keeps predators out, contains your flock, and lets the ground underneath recover between uses if you move it regularly.
Key Takeaways
- A chicken run needs 3 to 4 square feet of space per bird minimum, with sturdy framing and hardware cloth (not chicken wire) to stop predators from digging or pecking through.
- The frame is typically made from 2-by-2 inch timber or PVC pipe, with a roof to block rain and sun, and a door that latches securely.
- Hardware cloth must be buried at least 6 inches into the ground or bent outward along the base to stop foxes and raccoons from digging underneath.
- A portable run lets you move it every few days so chickens always have fresh grass and the ground underneath gets a rest.
- The whole project takes one to two days with basic tools: a saw, drill, staple gun, wire cutters, and a tape measure.
Choosing the Right Size and Location
Start by counting how many chickens you plan to house in the run. Each bird needs at least 3 to 4 square feet of space inside the run itself—more if they will spend most of their day there. A run for four chickens should be roughly 4 feet wide by 4 feet long by 2 feet tall, though taller is better if you want to walk inside to collect eggs or catch a bird.
Pick a location that gets morning sun but has afternoon shade, especially in hot climates. A spot under a tree or near a fence works well. Avoid low-lying areas where water pools after rain, because wet ground breeds disease and parasites. If you plan to move the run regularly, choose a flat area of lawn or pasture without large rocks or roots that will catch the frame.
Gathering Materials and Tools
For a basic 4-by-4-foot portable run, you will need:
- Eight pieces of 2-by-2 inch timber, each 4 feet long (for the frame)
- Two pieces of 2-by-2 inch timber, each 2 feet long (for corner braces)
- One sheet of plywood or corrugated plastic, roughly 4 by 4 feet (for the roof)
- 25 to 30 feet of hardware cloth (1/2-inch mesh is ideal; avoid chicken wire, which predators can tear)
- Galvanized wood screws (2.5 inches long) or galvanized nails
- A galvanized hinge and a sliding bolt or carabiner for the door
- Exterior wood stain or sealant (optional but extends the life of the frame)
Tools you will need: a circular saw or hand saw, a power drill, a staple gun with heavy-duty staples, wire cutters, a tape measure, a carpenter's square, and work gloves. A shovel is useful if you plan to bury the hardware cloth.
Building the Frame
Lay out your eight 4-foot pieces of 2-by-2 timber on a flat surface to form a rectangle. This creates the top and bottom perimeter of your run. Use a carpenter's square to check that the corners are at 90 degrees. Drill pilot holes at each corner to prevent the wood from splitting, then drive 2.5-inch screws through one piece into the end of the next. Use at least two screws per corner.
Stand the frame upright. Attach the two 2-foot braces diagonally from the top corners to the opposite bottom corners on two opposite sides of the frame. These diagonal braces stop the structure from racking (twisting out of square) when you move it. Screw them firmly in place.
If you want the run to be portable, attach handles to two opposite sides using rope or metal handles bolted through the frame. This makes it much easier to drag the run to a new spot every few days.
Attaching the Hardware Cloth
Unroll your hardware cloth and cut it into panels using wire cutters. You will need five panels: one for each of the four sides and one for the top. Start with one side. Staple the hardware cloth to the frame using a heavy-duty staple gun, driving staples every 4 to 6 inches. Pull the cloth taut as you go so it does not sag.
For the bottom, you have two options. If you plan to move the run frequently, staple hardware cloth to the underside of the bottom frame and bury it 6 inches into the ground at each new location. If you want a permanent installation, dig a trench 6 inches deep around the perimeter, lay the hardware cloth in the trench, and backfill with soil. Alternatively, bend the hardware cloth outward along the ground in an L-shape and pin it down with landscape staples or rocks—this stops predators from digging underneath.
Overlap the seams where two pieces of hardware cloth meet by at least 2 inches and staple them together. Check for sharp edges and fold them back or cover them with duct tape so the chickens do not cut themselves.
Adding the Roof and Door
Cut your plywood or corrugated plastic to size and attach it to the top of the frame with screws or bolts. Angle the roof slightly so rain runs off one end rather than pooling in the middle. Leave one corner or one side of the roof hinged so you can open it to collect eggs or catch a bird without having to disassemble the whole run.
For the door, cut an opening in one side of the frame large enough for a chicken to pass through comfortably—roughly 12 inches wide by 12 inches tall. Attach a piece of hardware cloth or a wooden panel to this opening using a hinge on one side. Add a sliding bolt or carabiner on the other side so the door closes and latches securely. Test the latch several times; it must be tight enough that a determined raccoon cannot nudge it open.
Finishing and Moving Your Run
explore exterior wood stain or sealant to the timber frame to protect it from rot and extend its life. Let it dry completely before introducing chickens. Check the entire structure for sharp edges, protruding screws, or gaps larger than 1/4 inch where a predator might squeeze through.
If your run is portable, move it to a new location every three to five days. This gives the grass underneath time to recover and prevents a buildup of parasites in one spot. Drag it by the handles or use a garden cart if it is heavy. Water the area where the run was sitting to help the grass regrow.
In winter, consider adding a windbreak on the north side using burlap or a tarp, and may support the run has good drainage so it does not become a mud pit. In summer, provide shade cloth over the top if the run sits in full sun all day, or move it to a shadier location during the hottest months.
Frequently Asked Questions
Can I use chicken wire instead of hardware cloth?
No. Chicken wire is designed to keep chickens in, not predators out. Foxes, raccoons, and weasels can tear through it easily. Hardware cloth with 1/2-inch mesh is much stronger and will last for years.
How often should I move a portable run?
Move it every three to five days if the grass is short and the ground is getting worn. In spring and early summer when grass grows fast, you can move it less often. In winter or dry periods, move it less frequently because the grass is not recovering as quickly.
What if I do not have a roof on my run?
A roof protects chickens from rain and sun, but if you do not have one, the run will still work—just move it more often so the ground does not become muddy or bare. Hawks can also swoop down and grab a chicken in an open run, so a roof or netting overhead is a good safety measure.
Do I need to bury the hardware cloth all the way around?
If you move the run frequently, burying it is not practical. Instead, bend the hardware cloth outward along the ground in an L-shape and pin it down with landscape staples or heavy rocks. This stops most digging predators. For a permanent run, burying it 6 inches deep is the most find option.
How much does it cost to build a run?
A basic 4-by-4-foot run costs between 80 and 150 dollars depending on the quality of materials and whether you use reclaimed wood or new timber. Hardware cloth and hinges are the most expensive parts. Prices vary by region and supplier.
