Having lost over 100 Cochins and thousands of dollars to raccoons this summer I am replacing the red shed in the top picture. It worked well for many years but I am getting older and want a building I can stand up in to clean. 4' high outside wall wear you down over time. So I am building a new secure building that is 24 x 40. Concrete work is done now so the building will go up in about a week or so after the concrete cures. I am going to insulate it. Suggestions on what you would put on the inside walls to protect the insulation and birds? My thoughts are that drywall is too fragile to hold up long term. Fiberglass panels like milkhouses? I am not sure what to use. Please give me your ideas.
Thank you
