Hi, I'm a newbie from NE Minnesota. I've been reading this great forum a LOT and have piled up a lot of info for planning my coop, run, how to care for chickens, everything I can find out about. At the risk of beating a dead horse, I'd like to hear more advice on coop size for areas where chickens might need to stay in the coop during a two week long, 20 below cold snap, or a snow storm and two feet of snow in the run. My city code requires "a floor area or combination of the floor and fenced in area for keeping chickens shall not be less than ten square feet of floor space per chicken". I'm planning on 10 sq. run per chicken, but I'm thinking the coop maybe should be a bit bigger than the BYC recommended 4 sq. per. Any ideas from you folks that right now have snow up to your belly buttons?
