Electric wiring or electric poultry netting for fencing is a great idea! It isn't that hard to set up either, even I can follow the directions LOL. With free ranging, you need to be prepared to lose birds. With only 6, it is possible that you can lose your whole flock in one day. I free range and have to be prepared every day that something bad could happen, but for me its the right choice to see my girls happy and doing what they love. I am only free ranging for a few hours before sunset right now, as they are all at POL, and I don't want them laying all over the land!
