So, I have a fenced in Run of 5' x 16' and it is covered with Chicken wire to deter hawks and other flying predators. that part is pretty well predator proofed. I have an extension on this run of the same dimensions. I used 4' chicken wire for the fencing part, but I do not yet have this portion covered, and they are yet to be introduced to the extension because of this. I was wondering what I could use for the cover, to keep out the event of climbing predators getting in, such as raccoons and foxes? I could buy more chicken wire and cover with that, but I am not sure that is predator safe, and it would sag, unless I put some sort of support up for it. I thought about using a tarp, but I am sure coons and fox could tear right through that. All this said, the chickens WILL be locked in at night. I am just trying to get an idea of what to use, and remain cost effective.
