If you want to keep your livestock in field boundaries, why not use stock fencing? It is an affordable form of temporary or permanent demarcation. We drive timber posts into the ground and staple these to the posts. Our stock fences include square meshes with heavy or medium gauge wires, fitted as per your requirements.
Deer fencing is primarily the same as stock fencing. It consists of longer posts and higher meshes to keep deer out of a given area.
