I am going to be getting a 8x10 galvanized steel shed this weekend. I need some advice on how to modify it for good ventilation for New Mexico summers, and keeping it warm in the winter. Or rather not drafty during the winter. I want to put some hinges, and larches so I can open and close which ever vents I need to. I'm also going to put brackets for the roosts. I'm going to put hardware cloth, and a floor in the coop. I'm going to use pressure treated 4x4s for the foundation, and put 2x4s for the floor joists, and put pressure treated plywood with linoleum on top as the floor. Do I need to put hardware cloth, or chicken wire under it? Also what's the best way to cut the metal so I can still keep it in good shape for me to use as "window" vents. Also can I put something on the metal to keep it from rusting? I really want to start putting it together and get my girls and boy in it. Any input is welcome. Thanks for the advice in advance.
