I can tell you that I never really used a blind To Hunt hogs....I always hid behind a Bush.... But I can tell you what I heard more than once In hunting camps in Texas.....Instantly popped up blinds spook hogs Around Feeders...... That you need to set them up and let them settle for about 3 days.However it has been experienced then a group of young and dumb hawgs, Meaning small, Might come crashing into the Feeder regardless.... But educated ones will come in and bolt away.
