I live in a somewhat rural area, and chickens are growing more common. I've had mine for about 2 years now, and they have always free-ranged. Our yard is only half an acre, but our neighbors don't have a problem with our quiet birds. We added a rooster in the fall, and while he does crow, he is a surprisingly quiet guy. Until recently. The other day, I noticed I was hearing a LOT of crowing. Not wanting him to become an annoyance to the neighbors, I followed the noise and went to find him. Instead, I found someone else's rooster! He was alone, and crowing over and over and over. My rooster was nowhere to be found, though the girls came when I called them. He showed up that night. Today, I hear more crowing, so I go out to see what the ruckus is. And this rogue rooster is in my yard! I chased him off with a broom, but in the meantime he started fighting with my rooster. A few minutes later, he had circled back around and was looking to pick another fight. This time I got my dog to help with the chase (he was a bit confused, as he has been taught to leave the birds alone, but the rooster didn't know that!), and I think we shooed him off for a while. I know this is only a temporary solution, though, as they seem to be in a territory dispute. What can I do? I have no idea where this rooster came from, but he doesn't seem to have any hens. Would a fenced chicken yard help? I like to free-range my birds, but not at the expense of their safety.
