Yes fibreglass insulation in the walls and the floor and ceiling are insulated with a styrofoam board insulation.Thanks! That information really helps! I will try a tarp over the run this year. Are your coop walls filled with fiberglass insulation? I was thinking about using blue board and then covering with some type of thin sheeting.
The walls , floor and ceiling are covered with plywood. Floor has vinyl flooring also.
Absolutely no way rodents can get to my insulation inside my Coop. Built like Fort Knox..
