I am using the poultry netting from Premier. I bought 300' of it just over a year ago, and have since bought 300' more, giving them a 100X200' run area. This, IMO, was one of the best things I have done for those chickens. I have a ongoing fox problem here. I lost 16 birds to them in two daytime attacks. I could not let the chickens out without somebody being there with them. Now, they get out everyday, and I don't have to worry about them anymore. As far as chickens going over the fence. I had one out of my nineteen, the first day the fence was up, go over. I gave her a clipped wing, and I haven't had a problem since. I am using the 48" high PoultryPlus netting. The posts are closer together, 8' instead of 12', the posts are heavier, with two ground stakes. I am powering mine with 115VAC. There is a solar powered charger available if that's what you want. Check out Premier's website, give them a call.
