I am currently looking for a good coop plan to house up to 6 hens for next spring. I live in northern Wisconsin, so definitely cold in the winter. I would prefer not to use a heat source since electricity will most likely not be available, and do understand the importance of ventilation without drafts. Maybe I'm being naive to think I can do this but I believe I can accomplish this with the right coop and breeds. I'd like to build and prepare the site this fall, so I'm ready for the birds next spring. Any info will be greatly appreciated. Thanks
