I found this thread on the topic- https://www.backyardchickens.com/forum/viewtopic.php?id=356156&p=1 I was wondering why I don't read more about other people doing this. It sounds brilliant! Maybe you do, but haven't mentioned it. I'm planning on it, as where we want to move to there's just too many predators to safely free range. Basically, I'll have my coop and then have at least two chicken yards attached to it. The chickens will be allowed out into one yard at a time. When the one yard starts getting hammered down, that pop hole gets closed and the new yard is opened to them with fresh, clean grass and other goodies in it.
