I enjoy gardening and will be fencing an area in soon. I plan to use wooden fencing around the perimeter of the garden and was wondering if a four foot height for the fence would be enough. I plan to use the chickens in between crops to get rid of the greenery in the garden and convert the garden shed to a coop during the time they are there. I also intend to use wire at the bottom of the fence to deter predators. Any advice on this would be appreciated. The size of the garden will be 40 ft x 60 ft.
