Hi, could you all share your opinions about the efficacy of chain link fencing in regards to deterring predators? I read that weasels can squeeze through 1" diameter poultry wire; the fencing of the dog run that I use as a chicken coop is at least 2.5." (Actually, I'm not sure if there are weasels in the Pacific Northwest, I should look into this.) But has anyone had bad predator-related experiences with chain link fencing and its inadequacy? I wonder too if possums could get through the large spacings. I am considering putting 1/2" mesh all around the base of the run. Any advice is appreciated. Thanks.
