Uh, because I agree but also don't. In some cases chicken wire is fine, in some cases hwc is better and in some cases neither will do a thing to protect your flock.
I agree to an extent. HWC is going to help stop smaller predators, but major things like bears it won't. But it also depends on the determination of the predator and any weak links in the structure, whether that be design or materials. I didn't vote.
