This is a combination of designs with a base design from John Suscovich’s book “stress free chicken tractor plans” except we used cedar lumber (we have a sawmill) and strategically wired it on the outside parameter and corners with electric fencing to protect what’s inside from predators on the outside or one can ‘jump off’ of that wire to an electric poultry netting fence to allow them to forage. We plug 3 100’ long drop cords together that just go with it as we move it. It’s a bit heavy to be honest, but it should last us indefinitely.
