Because of where I live, I have an electric fence. This has saved my grand kids many heart aches. Each time someone asks about them I have something to say. Before anyone puts up an electric fence they should go to this wed site redsnapr.com, I did. They have fence planning basics, fence tips for different animals types as well as the products needed to do the job right. They also have a support group taht will answer any questions you might have. Some sites tell you not to use barb wire, I do. The reason for this is if an animal get caught in the wire they could die. But for any animal like bear or coon with heavy fur you need the barbs to reach the skin. The above site or one like it is a must read before installing an electric fence. For those that still want to pee around the coop, don't worry that story about peeing on the electric fence is not true.
