I personally wouldn’t suggest lining the inside of a coop with styrofoam unless the chickens don’t have access to it. We tried to line the a spot on the ceiling with the blue styrofoam and the chickens pecked at it. I worried that they would eat it so we took it down.ive had chickens outside its -10 aslong as long they have a shelter they cano get away from the cold wind/draft and rain there fine, just make sure they get food and water, they have feathers thats what there for to protect them from the cold, you can line the inside of the coup with styrafoam foam insulation, its a pink color about inch thick and is moisture proof can get at home depot.
