Hi I'm a fairly new to this but I've researched a lot.. I'm having trouble deciding on where to put vents.... The house will facing east... We get a lot of north wind... I know it says not to put vents by roost ... Should I put vents going E & W or N& S? The roost bars run N&S.... We live near Memphis Tn so summers are hot!! I want to have enough ventalation to get rid of ammonia in winter bc I think I'm going to use deep litter in winter and sand in summer... But enough in summer bc it's hot. Any help would be appreciated !!
