I'd like to add the trespasser needs to be grounded.
So either on the ground, or touching something grounded. Most fences work, wood to a lesser extent than metal. You can probably go to a farm store and get some info although it's available online as well, with diagrams. If your soil is loose and sandy, the electric fence might not work as well as in a loamy damp soil.
the smaller the load (amount of wire charged by the unit) the bigger the pop will be. (why I opted not to buy a 60 mile unit off Craig's List. I want my dog to leave my chicks alone, but I don't what popdog either.)
Electric fencing isn't difficult;t to figure out once you know the basics.
Exactly. Ground rods properly situated is a must - but adding ground WIRES to the fence helps solve the grounding the trespasser problem.
The ground wire is attached to the ground rod terminal of the charger and is run like a normal strand of fencing. Especially where the soil is bad, but even if it's optimal.
Picture 4 strands, the top strand is attached to the "hot" part of the fence charger, the second one is attached to the "ground" part of the fence charger, the 3rd one is attached to the "hot" part of the fence charger, the bottom one is attached to the "ground" part of the fence charger. Positioned at heights such that the dog will have to touch at least one of the hot wires and one of the ground wires at the same time if it goes after the chickens, so no matter what it's doing with its feet- it will get shocked. (because the ground wire acts as the ground when the dog touches- it completes the circuit).
The math to picking a charger has to do with what material you're using as well as how far the fence is running. Polywire, polyrope and polytape are easier to set up than metal strands, but it's helpful to know that they have multiple strands inside the wire. Some have 6 strands, some have 9, polytape can have up to 15. So whatever the length of the fence, multiply it by the number of wire strands. i.e. 100 feet of 9 wire polywire is 900 feet of wire to charge. 100 feet of 15 wire polytape would then be 1500ft. I went with 9 wire polywire because it lasts, delivers the 12,000 without a problem and is easy to work with.
