I'm trying to decide if we should put a roof on the run or not. They'll have the 72 sq ft shed in winter so if the run gets full of snow it's not like they won't have space. I'll not ever have more than 5 chickens due to city ordinance so no chicken math to fight against. Who would roof the run and who wouldn't? If you would roof it, would you do corrugated metal or the corrugated plastic panels? I don't think the greenhouse effect would be an issue due to the afternoon shade. We don't want to just tarp it in the winter because of vanity - we're trying to be advocates for sustainable living and have it appeal to people who think it's ugly or dirty or too much work, etc.
Attached are a couple pictures from 2 years ago. The windows aren't boarded up now, of course, and we're in the process of painting it. The run will go where the corn is in the picture. And don't worry, we'll be digging up the daffodils!
