I need it to keep the chickens in
Just a note. I've been using the same fence for a year now and it keeps in MOST of my chickens. I have about 40 blkstars and there are now 6 that fly over every morning. I've clipped one wing & two, no difference. The chickens don't feel the electricity much (because I've seen them poking their heads through without issue).
It does keep other critters out. (My corgi will attest to that.) You may not have as much issue since you have a pretty large area and fewer chickens. (I bought two, so the area is pretty big.)
