I live in SE MN and this year we got 3 chicks. (Wyndatte, Sex Link, and Orpington) They are winter hardy varieties but I do want to keep them comfortable in winter. I know that they need good ventilation. We built a coop but it is a bit drafty (Ok in spring and summer and fall) but for WINTER I don;t think I will be able to insulate it enough so that it would still have enough interior room. My thought it to get a huge broken chest freezer - free, insulated, easy to clean, easy to install a window and vents into, and use that as a coop in winter. Has anyone seen this before? Google returns no similar hits, and I don't think I am smart enough to have hit on something no one else had tried. I know I need a nesting box, roosts, places for feed and water, access to outside....Any suggestions for what I might not be considering? This is either genius or complete idiocy.
