I am one of those with a Chicken Compound: multiple coops. And even though each group uses the latest coop for its grow-out period, and a while afterwards, the flock members do decide which coops they want to use as their roosting places once the latest batch o' youngsters are let loose to range with everybody else. . I don't worry that they make those decisions, I figure it's they're way of dealing with pecking order issues. Pecking order is fluid and dynamic, shifting as the flock grows and individual chickens mature.
