Welcome, and I'm so sorry for your loss! Build/ modify your shed and run to be as safe as possible, and be careful about free ranging. I lost ten (!) of my nicest hens one afternoon to a sick fox: that was not a good day. Electrified poultry netting is good for ground daytime predators, if it's available where you live. One meter high fencing won't work for much of anything. Good luck, Mary
