We just moved and have started free ranging our flock of 4 hens and 1 rooster. They are about 100-150 yards away from the house and for the first week they stayed near the back of our property. This week however twice I have found them closer and right next to the house. Is there any way to encourage them to stay closer to their hutch? They have plenty of area even further back from their coop that they can wander in. Any suggestions would be appreciated!!
