I want to make my new Hen Hoop more secure from predators, so I'm using hardware wire over the 1x2 welded wire that is used in the hoop. I have already covered "Area A" with hardware wire and fastened it securely. Area B is in question. Will 18" up from the bottom of the run be adequate, or should I cover more of the area? We live in an area where there are raccoons and possums, so reach-through is a real possibility. The girls will be free in the yard during the day when I'm home, but when I'm gone they will be shut in the run and coop area. They will be locked in the coop part at night. This is the people door. To put it in perspective, the hoop is about 4' tall at the highest point. I have covered the little chicken door at the bottom already, but I'm wondering how much of the rest of the front I should "laminate" with hardware wire. I'm also going to develop a "skirt" with the hardware wire to prevent dig under, but that is still in the developmental stages. Any input will be appreciated.
