Feeding stations. I can effect where birds range by placement of feeding stations. Place feeder(s) in location(s) away from where you do not want them to be. They will tend to concentrate their activities there. If more control needed, more than one feeding station can be used so they are some distance appart. Also try using different types of feed at each feeding station. In my experience the flock will move back and forth between stations, apparently in effort to get a balanced diet. I like to use BOSS and scratch at different locations and scatter them about to increase effort / time they are trying get their fill. If that does not work, then in addition try providing some sort of cover near or between feeding stations where they can loaf, again away from house.
