I've read a lot of posts but am asking about your experiences with using hardware cloth only as the bottom of the fencing around a run. Has anyone had a predator (hawks, coons, and possums here) climb up fencing and get through chicken wire? Will they climb to the top and get through chicken wire or netting? Will they access a roof of an attached building to come down into the run? What has been a successful for you to deter hawks from free ranging chickens in your yard or pasture? I only have three pullets and cannot afford to feed the wildlife! Thanks in advance for sharing!
