Has anyone used something called Electro Net (I think I have the name correct)? Basically it is electrified chicken fencing. It is hooked together like field fencing but closer together for chickens and it has electricity flowing through all the horizontal wires which are close together. I comes with its own fiberglass posts and you can place posts in the ground like a camping fence used for horses. It is supposed to keep 4 legged predators out--mostly. The chickens stay in also as long as the fence is hot enough. I live up against state forest and have many predators to think about. I have a very hot fence charger already and this fence sounds like an answer to my chicken prayers.
