We are thinking about doing this (temporarily) if we go on vacation next summer so we can keep the coop door open. There isn't anyone we know who is willing to come out here at 7 am and again at 9:30 or later to open/close and we are looking at alternatives to the auto openers (due to our coop design only allowing one type and also the cost). If we do this, how far from the ground and how far apart is best? Also dh said the grass growing up underneath would interfere with the hotwire so if you have this, do you put concrete or gravel or something around the run? Also how do you do the door area?
