I googled this question and got here. I'm confused by the premise that chickens only occupy 2-dimensional space, as they love to jump up and get on roosts and perch in high corners. It seems like having height in a coop must be good for something. For instance, I feel like a 54 square foot coop that is 6 ft. tall should be able to house more chickens than one that is 3 feet tall. Am I wrong??
