I put the plastic up on the coop today. The weather was so nice, it felt like I shouldn't be doing it yet, but I know that the weather can get horrible anytime now. The worst part is that we can't see the girls from our window anymore. The girls aren't sure what to think about it. They don't know what to think of the plastic and I know they wish that they could see outside, too. We'll all live through it, though, and I know this winter they will love having the plastic up so they have shelter from the snow and wind. This is the south facing side of the coop. I'm leaving the top panel of the door open right now. If it gets snowy in there, it wont' take that much to go out with a piece of plastic and staple it up. This is the east facing side of the coop. My clear plastic shower curtain wasn't big enough to do the whole side, but at least they can sort of see out. I left space at the top for ventilation. We don't get much wind from the south or east during the winter. The west and north sides are made of plywood, so no problems there. I'd love to see photos of what others have done to winterize. This is our first winter with the girls. Hopefully this will work out.
