So, I recently lost $300 worth of birds to a very persistent (and well known chicken-loving) fox. I live in the country, but our birds (chickens, ducks, and quail) are kept half a mile away (long story, tough situation). Frankly, all 20 of my 9 week old Wyandottes and 20 8 week old Quail were killed after I made the mistake of free-ranging my chicks and the fox dug under the quail coop to get inside. The chicken coop is totally foxproof, though, and I've built pens. Yet I want to go even further and was wondering what people's experiences with guinea fowl as predator control were. I'd free range and let fly a pair of guinea adults... Mostly as an alarm system for the chickens and intimidation factor for predators. How well might this work?
