Hello everyone! I am new to electric fencing and would like to install one in our property in order to keep my chickens and dogs inside of it. We have foxes and hawks and at the moment our chickens free range on 4 acres around our house. One of our dogs is also free ranging and does not wander far, however due to this reason one hen has been taken by a fox some time ago. Our other dog is a true protector but he would wander off away if given the chance so I would like to put up an electric fence around 4 acres which would keep my chickens and dogs together (they get along wonderfully). And would also like to use it in winter - we have snow and frost, and it gets till -20C (-4F) here in the winter. My question is - how many strands of wire should I use and at what height? And is metal wire a good option? And what kind of fence sticks (posts?) are best? Wooden stakes are pretty expensive but are those white, plastic ones strong enough to hold up and at what distance should they be positioned? And will this fence work in the winter? One of my dogs is a good jumper so I am worried he'll get over a lower fence. The highest fence plastic sticks are 140cm (4ft 7). Chicken electric netting is out of the question because it is super expensive here and only about 1 m (3 ft) in height. The total length of the fence would be around 350 m (1148ft). Forgot to mention that I am about to get guinea fowl for pest control so I am hoping the fence would keep them in. Some photos of my dogs and chickens who need a fence.
