Hi all! Uber newbie here in upstate New York trying to get ready for some fuzzy new friends, so just in the planning phase currently. If I'm trying to get appropriate air ventilation (draft-free, dry, healthy air circulation) inside of a 200 square foot prefab shed (sample pic attached), which of the following would you recommend: -one window on each side of the shed (allowing for a cross breeze) = 2 total -two windows on each side of the shed (allowing for a cross breeze) = 4 total -two windows only on one side of the shed on the south-facing side = 2 total -a cupola and vents all along the top of the shed with maybe one window -all of the above?! There will be two sets of double doors open all day, but closed at night with all animals inside for safety. Just wondering if leaving the windows open at night would create an unhealthy draft during pretty heavy winters and it would be better to have vents all along the top that are always open? Thanks for any help - much appreciated!
