I had received an Over ez large chicken coop for Christmas we are going to attach a fully enclosed run with roof panels to the coop . When we purchased the house the previous owner had a 4x45x33 dog run made with horse fencing attached to house. We would like to use this area as a second chicken run & are looking for ideas of how to enclose the top, we live in a rural area in northwest Florida .. we have hawks, racoons, fox, coyote etc.. this run area will only be used during the day while i'm working in my garden or doing yard chores.. The chicken coop run would be attached to the dog run area with a door in between to secure at night.. Would construction fencing work to cover the top work of the larger area ?? Or running rope zig zag across ?? Looking for ideas .. Thank You
