We have approx. 60 Barred Rocks that are 9 weeks old. We are trying to figure out why they are not all roosting. I would guess that only about 15 of them are roosting. Does this mean we don't have the roosts set up correctly? Can the roosts be at the same height or do they need to be stair stepped to accomodate the pecking order? Any suggestions? They seem to pile up on floor right inside the human door and we can hardly get in the coop once they are in for the night. Help, please!!!
