This will probably do nothing at all. To have affect the predator must be grounded.Walt do the chickens not touch it? Or is this on a outer fence?
I was thinking of putting a few 8ft lodge poles in my chicken yard with a hot wire at the top to see what they thought of that.
My electric fence strains start at 2 inches from the ground then rise at intervals of 4 inches with a total of 4 strains.
