DH and I are building a coop this week, so I'm doing tons of reading here. I've seen a lot about preventing drafts, but I think I'm a little stumped on what that means for me...it doesn't typically get incredibly cold here (although, it did get down to the 30s at night last month, which is rare), but we are prone to very strong Santa Ana winds. Do all sides of my coop need to be able to close, or can I have a side that is only covered by hardware cloth? I see a lot of "open air" coops, so I'm confused!!!
