I'm planning on free-ranging my chickens when they are old enough- I'll have 10 hens and 1 rooster. My neighbors also have about 10 hens and a rooster. There is a decent natural barrier (seasonal wetland with a small bridge) between our properties, but the two groups may come as close as 50 yards from each other. Will my rooster and the neighbor's rooster want to fight? Their flock never comes over to my yard now, but I'm worried about fights breaking out once my flock goes outside. Any thoughts?
