We must be overloaded according to the posts above, but our set up works and our hens are happy and healthy. We have fifteen hens overnighting in their cozy 4 x 6 coop. Laying boxes extend beyond the floor down the 6' side. They have one roost. Some sleep on it; others nest on the floor in deep pine shavings or in the egg boxes, usually snuggled up two in a box, clucking contentedly. I was sure this was too crowded, but I was proven wrong. Doors open out each of the 4' ends for day time breeze. I clean the coop and nest boxes daily, a quick chore that I do along with freshening water and feed, passing out treats, raking their yard. Takes very little time and the coop is always fresh for the next night. The coop is raised so they enjoy the shade underneath. The coop is set in their fenced and 4" deep graveled yard that is about 20 x 20. Ours is a different arrangement that seems to fit our hens' needs. ~G
