I know winter is far away and no one wants to think about it, but what do you do for shelter for geese in the winter? Right now when they need shelter the ducks and geese are under the chicken coop that is probably 2 feet off the ground with no sides. I want to build them a shelter for winter but don't know how insulated it needs to be (I live in New England). I want to build a hoop house type building and i am wondering if that will be sufficient or do they need a better insulated wooden structure? This is what i'm talking about http://www.oardc.ohio-state.edu/4hpoultry/t02_pageview/Hoop_House.htm. I'm going to put some plastic over it in winter.
