What You'll Learn

Planning and measuring the area
Once you have a general idea of the layout, grab your graph paper and sketch out a detailed plan. Include measurements and mark the materials you plan to use. This step will help you visualize the project and ensure you have all the necessary supplies.
When measuring the area, consider the width, height, and length of the tunnel. A width and height of about 40 cm (16 inches) provide ample space for chickens to move comfortably. However, you may need to adjust these dimensions based on the size of your largest chicken, especially if you have a rooster with long tail feathers.
Additionally, when planning the length of the tunnel, keep in mind that it should be long enough to provide adequate space for your chickens to roam and forage. You can also incorporate a second run or a new foraging area at the end of the tunnel to offer your chickens an even larger space to explore.
Finally, when selecting materials, opt for sturdy and flexible wire mesh that can maintain the shape of the tunnel. Choose mesh with holes no larger than 4 cm (1.5 inches) to prevent chickens from squeezing through and to keep out predators. Remember to cover the top and bottom of the tunnel with wire mesh for added protection.

Buying supplies
When buying supplies for your DIY chicken tunnel, it's important to consider the specific needs of your flock and the area you want to cover. Start by measuring the length of the tunnel you want to build and the width and height that will provide enough space for your chickens to move comfortably. A width and height of about 40 cm (16 inches) are standard measurements that allow chickens to move freely, but you may need to adjust based on the size of your flock.
Next, decide on the type of material you want to use for the tunnel. Chicken wire or welded wire fencing are commonly used options, and you can secure them with stakes, landscape pegs, or sod staples. If you opt for wire fencing, choose a sturdy, flexible wire mesh that holds its shape well and has small enough holes to keep predators out and prevent chickens from escaping. You can also use plastic resin chicken netting to cover the top of the tunnel, which will provide additional protection from wild birds and other predators.
To build the structure of the tunnel, you'll need support materials such as T-posts or wooden posts that can be driven into the ground to create a frame. Bendable rods or flexible wire can be used to create a dome-shaped top, providing more headroom for your chickens. If you want to add a pulley system for easy access, be sure to include the necessary hardware in your supply list.
Finally, don't forget to purchase UV-resistant zip ties to secure the wire mesh or netting to the frame. These ties are essential to ensure the durability of your chicken tunnel, as regular zip ties will snap over time due to sun exposure. With your measurements and materials list ready, you can now head to your local hardware store or garden centre to purchase the supplies needed for your DIY chicken tunnel project.

Constructing the frame
Once you have your measurements, you can begin to assemble the materials. The key component of the frame is a rigid wire mesh that will hold its shape. You can use welded wire, or opt for a roll of rigid wire mesh that can be unrolled and bent into a semi-circle or triangle shape. If you want to save money, you can also use thicker metal wire as a frame and wrap it with chicken wire secured by zip ties. To fully protect your flock, you may also want to cover the bottom of the tunnel with wire mesh to prevent predators from digging their way in. Make sure to use UV-resistant zip ties to avoid having to replace them over time.
When constructing the frame, start by driving T-posts or stakes into the ground to create a sturdy base. Attach the wire mesh to the posts, bending it into the desired shape. If you are using welded wire, you can join separate pieces together with zip ties. Make sure the frame is securely attached to the posts before moving on to adding the chicken wire.
Finally, attach the chicken wire to the frame. This will create a barrier that keeps your chickens in and any predators out. Use small-holed chicken wire to prevent smaller chickens from squeezing through. You can attach the chicken wire with zip ties or wire. Once the frame is complete, you can add a gate or attach one end of the tunnel to your chicken coop.

Adding a roof
Planning the Roof Structure
Start by measuring the width and length of your chicken tunnel. This will help you determine the size and shape of the roof you can build. Consider the height of your tallest chicken, especially if you have a rooster, to ensure they have enough headroom. Decide on the shape of your roof, whether it's a simple triangular or dome-shaped structure.
Gathering Materials
For the roof structure, you can use sturdy and flexible wire mesh, welded wire, or thicker metal wire. The wire should be rigid enough to hold the shape of the roof and provide stability. You will also need UV-resistant zip ties to secure the wire and prevent them from snapping over time. If you want to add a layer of protection, consider using chicken wire or plastic resin chicken netting over the wire framework.
Constructing the Roof
Begin by creating a framework for the roof using the wire or welded wire. Bend the wire into the desired shape and secure the joints with zip ties. If you're using thicker metal wire, you can wrap it with chicken wire for added strength and structure. Make sure the roof framework is securely attached to the sides of the tunnel to bear the weight.
Adding a Cover (Optional)
While some chicken keepers prefer an open-air roof, you can add a layer of protection by covering the wire framework. Use chicken wire or plastic resin chicken netting and secure it to the framework with zip ties. This will create a barrier against predators while still allowing airflow and sunlight into the tunnel.
Maintenance and Adjustments
Regularly inspect the roof for any signs of wear and tear. Check the zip ties and joints to ensure they are still securely fastened. Over time, you may need to replace the zip ties or make adjustments to the framework to maintain the stability of the roof.
By following these steps, you can effectively add a roof to your DIY backyard chicken tunnel, providing your flock with a safe and comfortable space to roam and forage. Remember to adapt these steps to fit your specific needs and the design of your chicken tunnel.

Finalising the enclosure
First, decide on the dimensions of your enclosure. A width and height of about 40 cm (16 inches) provide ample space for chickens to move around comfortably. When determining the height, consider the size of your largest chicken to ensure they can fit comfortably. It's also important to use mesh with holes no larger than 4 cm (1.5 inches) to prevent chickens from squeezing through and to keep out small predators.
Next, assemble the necessary materials. The primary material you'll need is rigid wire mesh, which is essential for maintaining the shape of the tunnel. Additionally, you'll require stakes or landscape pegs to secure the mesh in place. It is recommended to use UV-resistant zip ties to bind the mesh together, as regular ties may snap over time due to sun exposure. If you're particularly crafty, you can repurpose old wire by bending it into shape, but ensure there are no large holes that chickens can escape through.
When constructing the enclosure, start by driving stakes or T-posts into the ground to create a sturdy framework. Stretch the wire mesh over this framework, securing it tightly with zip ties. If your enclosure is adjacent to an existing fence, you can attach the mesh to it for added stability. Don't forget to cover the top of the enclosure with mesh as well to prevent wild birds from entering and to provide protection from above.
Finally, consider the access points to the enclosure. You can leave the tunnel open at one end, allowing chickens to roam freely between the tunnel and a fenced area. Alternatively, you can install a gate for easier access and better control. If you have an old gate from a previous project, you can repurpose it by replacing the hinges with elastic straps, ensuring smooth operation.
By following these steps, you'll have a functional and safe enclosure for your DIY chicken tunnel, providing your feathered friends with ample space to roam and enjoy their new playground.
