Quick question to those of you who have built coops before: Is there much to be gained by installing interior walls? Right now, the main benefit would be the ease of cleaning a flat surface instead of having to scrub inbetween my 2x4's in the walls. Currently, I have the outer OSB panels in place only, and wanted to know whether it was necessary to put up some interior walls to cover the studs inside. At this point, i'm leaning against insulating the walls. If I did, I think I'd use some of that thin(1/8" thick) laminate wallboard that you typically see behind washing machines . What are your thoughts?
