Replying on the red tailed hawk gave me an idea. Some of the more obscure catalogs, like Lillian Vernon and Dr. Leonard's, advertise a device that looks like a single sprinkler head. It's designed to shoot a blast of water when something moves in the path of it's motion detector eye. I'm thinking it might help to have 2 of em, one on each side of a chicken coop at night. They're not that expensive, and if they don't work I could always cover the md eye and use them as a regular sprinkler.
Anyone ever heard/tried such a thing?
