Ahh, this is clever. Thank you each for pointing towards this. However I need to be careful not to cut down my ventilation, as 1square foot per bird takes up most of the slanted upper portion of the structure as it is. I won’t have a pile of snow directly outside the vent… perhaps a thinner version would suffice? Also, any ideas what percentage this, or a thinner version, will reduce ventilation by?
