I recently made a post about using electric fencing in the new coop I was building. I got some responses but they were from the coop design/construction forum and one reply said that electric fencing is mainly only good for keeping chickens in not for keeping predators out. I'm not saying I don't believe them I just thought I would come here and get a second opinion from the forum specified for predators. Here is my situation, I'm building a 1000 square foot run for my chickens(and soon to be guineas) and I've decided due to costs I would leave the top uncovered, using electric fencing to keep the predators out. I only have one real predator here and that's raccoons. We have the seldom hawk or coyote but I just need to focus on coon prevention. My plan was to run two, possibly even three strands at varying heights around the length of the run. I figure at 1 foot off the ground, 3 foot and maybe one around the top of the fence at 6 foot up. The chickens would not be able to get to this fencing, it will be just on the outside of the main 6 foot fence. Is electric fencing as I've described enough to keep raccoons out? The coop will be extra fortified with a pop door shut every night. I plan on running the electric fencing nearly around the clock, is there anything bad about this or any suggestions to make?
