Went out to check the chickens this morning and wouldnt you know it, a buff laced polish juvenile was awol. My barn is two inches of the property border fence between my place and my uncle's and on his side I found a foot and a wing. We have solid siding on that side of the barn except the bottom four inches which has welded wire 2 in by 4 in. So we spent this morning running a strand of electric fencing three inches from the ground all along the barn and outside runs. My question is this: Do i need to run another strand say about five or six foot off the ground to prevent them from jumping that strand and climbing the 2 x 4 welded wire and entering the runs?
