I want my chickens to till up (eat all the grass) a section of my lawn which I will be using for more garden space next spring. They are free range, and although I do have a chicken tracor, it would be too small and it is too cold to cover the large area effectively right now. Ideally, I would throw up some electic net fencing on the warm days and lure a few hens in there to work. But I don't want to shell out the $300, and am looking for suggestions of alternative ways to put my chickens to work where I want them. My concern is not predators, it is keeping the chickens where I need them. I read where a person used one single strand of wire 5-6 inches off the ground effectively, but I am skeptical as my hens fly over/roost on 4 foot high fences surounding their coop. Anybody have any suggestions? I am physicaly fit but poor, so keep that in mind PS my boyfriend has a lot of fencing supplies for cows that I can borrow Thank you all!
