As I have been raising birds for a long time myself, I really never took stock in protecting my pheasants with an electric fence. My main predator here are racoons. They are very crafty and will find a way around an electric fence. My simple way to keep them out was to put some old corrugated tin around the sides of my enclosure, burried six inches in the ground. I have two widths of the tin high to make the racoons need to try to scale 3 1/2 feet of unclimbable situations. The other four feet of enclosure is 1" chicken wire to deter them from getting in IF they actually find a way over the corrugated tin barrier.
