Thank you! The two different tractors we use have very different uses. We use the John Suscovich chicken tractor for eating grass, localizing the manure and creating simply a healthier and happier bird. The one in the video is just a coop on wheels that they can lay eggs in, but we use it to keep them in a broader area and "free range" with limitations. Depends on what you're wanting as to which way you can go. Either way, we have free ranged our chickens for many years and they inevitably end up where they aren't supposed to be (eating the garden, pooping on the porch, etc.). So, keeping them contained and mobile has ended up working best for us. Thanks for stopping by!
