Ericz, I think you need to cover your run with something stronger than chicken wire. A lot of different predators will go through that, including dogs and raccoons. Unless you have dogs guarding your property that are out there all the time, chicken wire is not enough. I would at least layer a stronger fencing over the top of it around the bottom, like a 2" x 4" welded wire fencing. That will help keep out dogs. I've only seen a dog go through that once. Chicken wire is weaker, since it's made with a finer wire and also stretchy, because it's only twisted, not welded. It's easier for animals with strong jaws to get a grip on it, stretching and tearing holes in it.
