I started with 8 guineas. Lost two while they were young. Lost four more from an attack by some animal at night. Feathers were everywhere, so it probably wasn't a fox. Most likely my neighbors yellow lab. Today, my wife said that my last two guineas went over to the neighbors yard and their lab killed one! It makes me sick! The last two were a male/female pair and they were laying eggs, so I was hoping to increase my flock. I want to allow my guineas to free-range so they can eat up all the bugs and weed seeds, but how do I keep them on my property? I have found out from some of my other neighbors that they have been wandering around their yards too. I let them out in the morning and they are back in the coop at night when I lock them up for protection. My neighbors don't mind them wandering around their property, but I can't get mad at them either when their dog kills one on their own property. I live out in the country with 7+ acres and woods all around. Unless I put the "invisible fence" collars on each guinea like my dog has, I don't know how to keep them 'home'. Any help would be appreciated.
