A friend sent me this interesting approach to safeguarding the entrance to the coop by building a "hot plate" on the pop door ramp. Has anyone ever tried this?
"A low-strung electrified wire wraps around Darren Bender-Beauregard's chicken coop in Paoli IN, and is attached to this metal plate at the entrance. The chickens hop up and are not shocked unless they have one foot on the ground...but they always hop up....unlike the unwary raccoon, possum, skunk, snake, etc., who learn REALLY fast not to repeat the attempt. Darren found he could leave the coop open full-time and never worry about predators."
I'm skeptical about how this would work. (Apologies if this has been posted before since my Search term "Coonzapper" didn't turn up anything.)
