Now that the coop is up, I've got to plan on how to arrange the inside. It's an 8X8 with 4x2 windows on 3 walls about 4-5 feet up. I have EE's, Orps, Wyandottes and Brahmas. I was thinking having one long bar all across one side about 5 feet up. Would they be able to get up this high? Do I need to have an intermediary roost closer to the ground?
