Definitely have ventilation at the top and two windows that allow airflow in hot weather. My goat shed was my chicken coop. I have vents on all 4 sides. As far as my window goes it doesn't open and I need to put a plexiglass cover over the window so my goats don't break the old glass window. My floor is plywood and insulated, with a sheet of Lino flooring to easily clean. I use pine shavings.
