My girls are now 17 weeks old so I am doing coop maintenance and uncovering the nest boxes. My coop is 4' wide with a roost bar spanning the coop at 47" wide. I have 5 chickens and always intended to add a second roost bar when they got older. At this age, they all crowd around one side of one roost. Is there any point in adding the second bar? They are Easter Eggers, so medium sized birds. Will they ever spread out and need more roost space?
