HI...we are finishing up our coop (if the weather will cooperate) and need some advice on the run area. We are going to make it 5 x 12 but do not know if we should make it short, or tall enough for me to walk in. It will be covered in 1/2 inch hardware cloth all over as well as the floor area to deter predators. At least four inches of sand for the flooring over the hardware cloth and a lightweight removable cover for when the weather is bad. We see so many different heights on here so can you tell us........ WHAT WORKS BEST FOR YOU?????
