Andy, what are the dimensions of the coop drawing you made (length, width, height)? I love your drawing, but I'm concerned about your chickens not having enough space.
I'm a really visual person, so one thing I like to do when I'm planning something is take some masking tape and actually mark out on the floor the size of whatever it is I'm thinking about building. Remember, nestboxes, roosts, etc., will take up a lot of room. Think about cleaning the coop and what your tools might bump into. It might be more annoying than helpful to have a two-foot-wide coop. The dimensions in your original post are very, very small.
