We picked up our first 4, 9-week old hens today. Below is my coop. It is 4'x8' and 6' tall in the center. On this side you can see the door to the next boxes and then the entire lower half flips down to allow full access to inside the coop. In the picture below you can see that the front half of the front half flips open and the front gate comes out completely allowing access into the run.
