Design and planning

Building an A-frame chicken tractor requires careful design and planning. Before you start building, it's important to consider your shelter needs, flock size, and the materials you'll be using. You should also determine the size of your flock, coop, and land, as well as how often you plan to move your chicken tractor. A ratio of 1-3 chickens per tractor is ideal for providing fresh grass and clean space for foraging.

When it comes to materials, you can choose between repurposed items or supplies purchased from a hardware store. If you're looking for a lightweight and easy-to-move tractor, consider using 2x2s instead of 2x4s for the frame. You'll also need plywood, hardware cloth, and a metal flashing for the roof. For added durability, you can use solid painted steel roofing for the roof and sides, while using chicken wire for the front and back to provide airflow and protection from predators.

It's important to have some building experience before tackling this project. You should be comfortable using power tools, taking measurements, and following directions. Reading through the plans, understanding the steps, and taking measurements before cutting are crucial to a successful build. If you're unsure about a step, use cardboard to map it out first.

To make your tractor mobile, follow the wheel design provided in most build plans. This will ensure ease of movement. Additionally, consider adding a custom tow bar to move the tractor with an ATV or garden tractor. For added convenience, you can install a chicken guard to operate the door in colder weather.

Building the frame

Building an A-frame chicken tractor requires some building experience and the right tools. You should be comfortable using power tools, taking measurements, and following directions. Before you begin, it's important to read through the plans in their entirety to understand how all the steps fit together.

The first step is to decide on the design and layout of your mobile coop. This will depend on your shelter needs, flock size, and the materials you select. You can use repurposed items or purchase new supplies from a hardware store.

When it comes to the frame, you can use 2x2s or 2x4s. Using 2x2s will result in a lighter and easier-to-move structure. Start with a basic design and add the features you want. For example, you might want a removable egg-laying pan that can be pulled out and cleaned without entering the tractor. You can purchase an aluminum pan designed for a rabbit hutch, which works well for this purpose. You'll also need to consider the placement of doors. For example, you might want a hinged door for accessing the laying pan and another door at the bottom for refilling food and water.

If you're using 2x2s, be sure to add plenty of bracing for attaching the plywood and hardware cloth that will encase the A-frame design. The rafters should be notched at the top to allow the ridge beam to sit on them, providing a nailing surface for the rafters to connect to the beam and offering a solid resting surface for support.

Once the frame is built, you can add hardware cloth and plywood to the sides. Stain the plywood with Spar Urethane before attaching it to the frame. Don't forget to add hinges and latches to the doors to increase security. Finally, add a piece of metal flashing along the top for additional water protection.

Adding doors and features

When building an A-frame chicken tractor, you can add various doors and features to enhance its functionality and convenience. Here are some detailed instructions and ideas for adding doors and other features:

Adding Doors:

  • Consider installing multiple access doors: Having more than one door can make it easier to collect eggs, throw in scraps, and manage your flock. For example, you could have a main door and a smaller hatch on the top for throwing in scraps, as well as a side hatch for the nest box.
  • Use appropriate materials: Chicken tractor doors can be made from various materials such as wood or metal. Ensure that the material you choose is durable and weather-resistant, especially if you plan to keep the chicken tractor outdoors.
  • Ensure proper sizing: The size of the door should be proportional to the size of your chicken tractor and the number of chickens you plan to keep. It should be large enough for the chickens to enter and exit comfortably, but not so large that it affects the structural integrity of the tractor.
  • Include hinges and latches: Install sturdy hinges to attach the door to the tractor and a secure latch to keep it closed. You may also consider adding a lock for added security.
  • Prevent warping: Wooden doors may be prone to warping over time. To prevent this, consider using diagonal braces across the width of the door, especially if it is a large door. Proper bracing will provide support and help keep the door flat.

Other Features:

  • Nest box: Create a comfortable and accessible nest box for your hens to lay their eggs. You can get creative, like using part of a dryer as a nest box, as mentioned by a chicken tractor owner.
  • Roof and sides: Cover the roof and sides with solid painted steel roofing to provide protection from rain, shade from the heat, and durability against strong winds.
  • Front and back: Surround the front and back of the tractor with chicken wire to allow for airflow and ventilation while keeping your chickens safely enclosed.
  • Wheels: Include wheels in your design to make the tractor easily movable. The Green Willow Homestead's build plans include a special wheel design that keeps the tractor both mobile and durable.
  • Tow bar: If you want to move the tractor with an ATV or garden tractor, you can add a tow bar. Green Willow Homestead offers a custom tow bar made of thick-walled steel tubing and laser-cut steel plates.
  • Automatic door: Consider installing an automatic door, such as the Chicken Guard Extreme, which can be useful for colder weather and if you need a heavier ramp.

Making it mobile

Building a mobile chicken coop has proven to be a success for many. The layout of your mobile coop will depend on your shelter needs, flock size, and the materials you select. You can use repurposed items or supplies purchased from a hardware store.

To make your chicken tractor mobile, you must ensure that it is not too heavy. One builder recommends using 2x2s instead of 2x4s to make the tractor lighter and easier to move. Another builder cautions that their tractor became very heavy and nearly impossible to move by hand after they added a second layer to increase headspace. They had to hitch it to a lawnmower to move it around their property.

You can also make your tractor mobile by installing wheels. One builder provides wheel designs in their build plans, making the tractor extremely easy to move. Their custom tow-bar features thick-walled steel tubing and precision laser-cut steel plates that easily bolt together. The tow bar mounts to the tractor using quick attach/detach cotterless hitch pins.

If you want to avoid the hassle of building your own, you can purchase a chicken tractor wheel mounting kit.
