I am in the process of finishing up the final touches on my coop and I have put lots of nice ventilation by not having the walls go all the way to the roof. I was thinking of covering these large vents with some spare screen I have laying around to help keep some of the flies, bugs, etc. out of the coop. However, someone recently mentioned to me that having the screen may also trap dust and dander etc.inside the coop which would not be a good thing.
Can anyone share their advice or experiences please.
