Our oldest set of chickens are 14 weeks old. They have been free ranging for about 3-4 weeks now. The first few weeks they stayed within 20 yards of the pen, now they are wondering all over. We have 10 acres- the first 2 are what we use daily, so lots of oak trees and bushes, but also lots of roaming room. The back is all forest. They started wandering in the front of the house the last few days- and going closer and closer to the road. To the point today that a car scared some and they ran back. Is this just the way it is? Will they learn? Should we shoo them from the road? The road is at least 200 yards from their house.
