Digging Trenches For Chicken Runs: How Deep Should You Go?

Chicken runs are fenced areas that allow your chickens to roam freely while keeping them safe from predators and preventing them from wandering into unwanted areas. To build a chicken run, you need to dig a trench around its perimeter and sink fencing into it to prevent predators from digging their way in. The depth of the trench can vary from a few inches to a foot or more, depending on the type of predator you are trying to keep out. Some sources recommend using chicken wire or hardware cloth in the trench, while others suggest gravel, rocks, or concrete for added protection. The size of your chicken run should also take into account the number of chickens and the potential for your flock to grow over time.

Trench depth: 4-12 inches to prevent predators

When building a chicken run, it is important to consider the depth of the trench to prevent predators from accessing the chickens. While the specific depth can vary depending on the type of predator you are trying to deter, a general range of 4-12 inches is recommended to prevent digging animals from gaining access to the run.

Some sources suggest that a trench depth of 4 inches is sufficient to deter predators. This depth is recommended by sources suggesting the use of hardware cloth, a type of wire mesh, which is attached to the bottom of the run and then buried vertically in the trench. By having the hardware cloth extend downwards, predators will be unable to dig their way into the run. This method is suggested as a minimum depth of protection, with some sources recommending going deeper if possible.

Other sources recommend a trench depth of 6 inches for burying chicken wire or hardware cloth. This depth is suggested as a balance between providing protection from predators and minimizing the amount of digging required. One source mentions that predators typically dig within a few inches of the fence, so having the trench at this depth will deter them before they can gain access.

In some cases, a deeper trench of 8 to 12 inches may be recommended. This increased depth provides an additional layer of protection against more persistent digging predators. One source mentions that a trench depth of 8 inches was sufficient in their experience to keep out skunks. Another suggests a depth of 12 inches for the first fence post hole, with subsequent holes being 4 inches deep.

It is worth noting that while trench depth is important, the horizontal distance of the trench from the base of the chicken run is also a key factor in predator prevention. Extending the trench outwards from the base can make it more difficult for predators to dig their way into the run. Additionally, some sources suggest using alternative methods, such as laying rocks or railroad ties along the bottom edge of the run, as effective alternatives to digging trenches.

Trench width: 12-18 inches for protection

When building a chicken run, it is important to consider the width of the trench to ensure that it provides adequate protection for your chickens. While the depth of the trench can vary, with some sources recommending a depth of 4 inches (10 cm) and others suggesting 12 inches (30 cm), the width of the trench should be given equal consideration.

A trench width of 12-18 inches is recommended for optimal protection against predators. This width serves as a barrier to prevent animals from digging their way into the chicken run. By extending the trench outward from the base of the coop, you can make it more difficult for predators to gain access. This method is often referred to as creating an "apron" or "skirt" around the perimeter of the run.

The key to an effective trench is to ensure that it extends far enough horizontally from the base. This will deter predators from digging their way into the chicken run. While the depth may vary depending on the type of soil and local predators, keeping the width consistent at 12-18 inches will provide a strong layer of protection.

To further enhance the security of your chicken run, consider using hardware cloth or welded wire fencing. Burying this material in the trench can create a physical barrier that predators cannot penetrate. Make sure to attach the fencing securely to the posts and coop to prevent any gaps that predators could exploit.

Additionally, combining the trench with other protective measures can create an even safer environment for your chickens. For example, you can attach fencing to the top of the run to protect against climbing or flying predators, such as foxes, raccoons, and birds of prey. By implementing these measures, you can provide your chickens with a safe and secure environment while deterring a wide range of potential threats.

Chicken wire: bury it or use rocks

Chicken wire is an effective way to keep your chickens in their run and protect them from predators. However, digging trenches for wire can be a tedious and challenging task, especially if you have hard or rocky soil. So, should you bury chicken wire or use rocks to secure your chicken run?

Burying chicken wire is a common method to prevent predators from digging their way into the run. The general recommendation is to dig a trench around the perimeter of the run and bury the wire a few inches below the ground. This method is effective against digging predators such as skunks, coyotes, and dogs. It is important to note that chicken wire may not be as effective in keeping stronger animals out, as they can sometimes tear through it. Additionally, burying wire may not be feasible if you have a large area to cover or if your run is not in a permanent location.

Using rocks to secure chicken wire is a less labour-intensive alternative to burying it. One effective method is to lay the wire flat on the ground around the outside of the coop and attach it to the wire sides of the run. Then, place large rocks (20-30 pounds) along the wire, stacking them two or three high. This method provides a physical barrier that deters predators from digging their way in. It also prevents them from following the wire straight down into the ground.

Another option is to use a combination of trenching and rocks. Instead of burying the wire deep into the ground, you can dig a shallow trench and lay the wire in an L-shape, extending it horizontally outwards from the base of the coop. This creates a "predator apron" that prevents animals from digging their way in. You can then use rocks to weigh down the wire and create an even more secure barrier.

Ultimately, the decision to bury chicken wire or use rocks depends on various factors, including the type of predators in your area, the effort and cost involved, and the permanence of your chicken run setup. Burying wire is a traditional method that offers good protection against digging predators, but it can be time-consuming and may not work against stronger animals. Using rocks provides a physical barrier that deters predators and is easier to implement, but it may not provide the same level of protection against burrowing animals.

In conclusion, both burying chicken wire and using rocks have their advantages and considerations. By understanding the specific needs and challenges of your chicken run, you can make an informed decision on which method to choose or even combine elements of both for effective predator protection.

Fence posts: dig holes, concrete them in

To build a fence, you need to start by laying out the fence posts. Mark the locations of the posts and the gate before installing them. Use graph paper to draw a plan for your fence, noting the post and gate locations. Check all local codes for fence style, size, and placement, and make sure you know your property lines. Call to have underground utilities marked before you begin digging.

Once you have a plan, you can start digging the holes for your fence posts. Digging post holes is easiest with a power earth auger, but a shovel or spade can also be used, especially if you need to cut overgrown roots. A spud bar or a tile spade can help to loosen the soil and carve away at the sides. Throw the dirt onto a tarp to protect your lawn. If you're digging in sticky clay soil, dip your shovel in a bucket of water to prevent the soil from sticking.

The depth and diameter of the holes will depend on the local building code and the type of fence you are building. For a 4x4 post, the diameter is typically 12 inches, and the hole depth should be below the frost line. The post holes should be deep enough to accommodate the gravel at the bottom and the concrete. Generally, holes should be dug to a depth of 30 to 32 inches.

After digging the holes, you can start setting the fence posts. Place the posts in the holes and use a level to ensure they are straight. Use a measuring tape to space the posts equidistant from each other, typically 6 to 8 feet apart. Once the posts are positioned correctly, you can start adding the concrete. Break bags of dry concrete into the holes and pour in the recommended amount of water. Allow the concrete to set for an hour before removing any supports.

Cover the top of the fence with 2x4 or 1x6 boards to create a frame, screwing the boards horizontally into the posts for added stability. This will help to sandwich the fencing in between the posts and provide extra security for your chicken run.

Chicken run: attach to coop, cover the top

Chicken runs are outdoor enclosed areas that allow your chickens to roam freely while keeping them safe from predators. The first step in building a chicken run is to dig holes for your fence posts. Sink the posts in concrete to ensure they stay put. Use a level to make sure they are straight, and a measuring tape to ensure they are set equidistant from each other—about 6 to 8 feet apart is a good distance.

Next, attach the wire fencing to the posts using staples (u-shaped nails) and a hammer. Staple the mesh every 6 inches, securing it tightly to the posts. Make sure the wire is attached to the chicken coop itself as well. You can attach the run to the side of the coop by cutting a chicken-sized hole in the side of the coop and a slightly larger hole in the fence. Tightly bolt the fence to the side of the coop so predators can't get in.

To prevent digging predators like coyotes and dogs from accessing the run, dig a trench around the perimeter and sink the fencing down a few inches. Some sources suggest that trenching is not necessary, and instead recommend lining the bottom edge of the run with railroad ties or gravel, shale, or granite mixed in the soil as a barrier against diggers. Another option is to lay a 1-foot-wide layer of heavy-gauge chicken wire or welded wire flat on the ground around the outside of the coop.

Finally, cover the top of the run to prevent climbing predators like foxes and raccoons, as well as aerial predators including hawks, eagles, and owls. Use 2x4 or 1x6 boards to create a frame, screwing the boards horizontally into the posts along the bottom, middle, and top of the fencing for added stability.
