Here are some steps you can follow to make a mobile poultry structure:

1. Determine the size and type of poultry you will be housing. This will help you determine the size and number of mobile structures you need to build.
2. Choose a suitable location for the mobile structure. It should be a flat, well-draining area that gets plenty of sunlight.
3. Gather the materials you will need, including wood or metal framing, wire mesh or hardware cloth, roofing material, and any other supplies you will need.
4. Build the frame of the mobile structure using the wood or metal framing. Make sure it is sturdy and well-supported.
5. Attach the wire mesh or hardware cloth to the frame to create the walls and roof of the mobile structure. This will allow sunlight and fresh air to circulate while keeping your poultry safe from predators.
6. Add a door or gate to the mobile structure so you can easily access the birds.
7. Cover the roof of the mobile structure with the roofing material to protect the poultry from the elements.
8. Add bedding, such as straw or wood shavings, to the inside of the mobile structure to provide a comfortable place for the poultry to rest.
9. Place feeders and waterers inside the mobile structure to provide food and water for the poultry.
10. Move the mobile structure to a new location on a regular basis to give the poultry access to fresh grass and insects. This is especially important if you are raising chickens, as they love to scratch and forage in the soil.
