My B.O.'s are 13 weeks old? They still huddle together on the floor at night. I know they know how to get on the roost, I have seen them hangining out there in the morning before I let them out of the coop. But when I lock them up at night, they are huddled on the floor. Also, I don't have my nest boxes built yet, when would I expect them to start laying eggs. 5 months?
