I have my poultry fence (50ft) wrapped around my coop-shed. The tester says 2 Kv, does anyone know if that's enough to deter raccoons from getting in the windows. My Gallagher charger says .26 joules and .40 store joules...up to 25 miles. I don't have the ground rod as deep as it can go and was wondering if I should keep pounding it in. Thanks!
