I am new to raising backyard chickens and have a very elementary question. Everything I am reading on the size of coop I require is 10 square feet per chicken (since mine are not able to free range). But, here is my question: Is the 10 sq/ft "including" my run, or is that strictly the size of the coop I need to make sure these girls have plenty of room? I am looking at a building a 10wx8d coop with a 10wx12L run which will make it 10x20 overall and achieve my 200 sq/ft. Will this be sufficient?
