That's the towed-array integrated poultry and apostate scanner used by the Baptists to detect heretics, blasphemers and chickens. The multispectral transducer can detect one part per billion of wine or ammonia, as well as minute vibrations caused by dancing, and who knows what else. The data is electronically linked to a processing unit in Alabama, from where the Christian Enforcement League is dispatched. They come in the middle of the night. There are a lot of empty homes around here the day after they scan our brains. None of those folks are ever heard from again. If your coop wasn't clean, or if you had any impure thoughts while you were being scanned, I'd be heading for parts unknown before dark if I were you.
