I worry that if she keeps letting them free range, her chickens may stop coming home and start roosting over there.My chickens were hatched 4/30 this year. They were doing the same thing but with my cockerel leading the pack. They were not visiting a nearby farm. They just wanted to wander further and further away.
They now spend most of their days in the newly fenced in 1/4 acre pen I made for them. I let them out about 1 - 2 hours before dusk and that has kept them from going too far.
