Hi everyone,
I'm thinking about winter already, and the vents in my coop. I have 2 on each side, covered by duct vent covers. (See below). I was thinking that when it starts getting colder I might put those litterbox filters under the vent covers to keep it from being too breezy. (They're kind of like those thin pot scrubbers you can get). Would this cause problems with ventilation? Right now the roost is next to one of the vent, so they could get breezes at night when it was warm. But I know they don't want that in the cold, so I suppose my other option is to move the roost into the middle between the vents. Any thoughts?
Here's a picture of the coop and vents (obviously I plan on shutting the window in the cold as well):
