Anyway, the problem - I finally have DH on board, ready to build me a coop and get me a nice little flock of layers running around here. Unfortunately, the neighbors became convinced a little faster than DH did and now THEY have a flock of about five or six hens and a rooster. We are on side-by-side two acre lots. The only fencing is what we have up for the horses - it keeps the horses in, but doesn't keep small animals (ie chickens) in our out. The neighbor's chickens routinely wander their yard, our property and even into the property on the other side of us. I don't mind this AT ALL (though, I do find it ironic as when we had our ducks they wandered into their yard ONE time, they immediately came over to complain and I spent the next day erecting fence on the front side of our house to keep them penned in near our pond), but I am wondering how this might work out if/when I get chickens of our own. Growing up this wasn't ever an issue as we were on five acres in the middle of forty acres of hay fields - the closest chickens to our property were about three quarters of a mile from us. What, if any, possible concerns are there when flocks mix and mingle?
