I lost two big hens this week by raccoons. So I buy an electronic fence to prevent them. The instruction said I need a metal ground rod to reach the permanent wet earth. However, my house is locating on the hill and there are lots of rocks under the earth. I don't think I can install the ground rod that deep. So I have to try the two-wire system. Can anyone tell me for the best prevention from raccoon, what is the height bewteen ground and the ground wire, and the height between ground wire and fence wire? Thank you.
