This morning I went out to check on my girls (and the surprise roo) and as I was putting in their fresh water I got dripped on. I looked qup I was thankful that it wasn't a chicken with a runny nose but was not excited to see condensation running down the inside of the roof. I'm located in SW Michigan and the roof is made of the wavy vinyl that you can find at Lowe's or another home store. I have venting right near the top so I'm trying to figure out why I have so much moisture buildup. The coop is 5x6 and 4' tall and 2' off the ground (so roof height is 6'). The walls are insulated but the roof isn't. We have 8 standard birds. We could have snow by the end of the week so I want to make sure they are cozy before the real cold sets in. Any suggestions or ideas would be greatly appreciated.
