Many of you have seen my little coop (see avatar). I just have a couple questions about winterizing it. This side faces north: Here is the same end from the inside. I did put foam board insulation under the roof this weekend. The south end has the same vent in the gable, the south walls are windows. I have trim boards that I left off for the summer, that could be put on to cover the gap above the gables. I was also thinking about putting a piece of plywood on the inside of the coop to cover the 4 wall vents. The pop hole is on the south side and has heavy plastic strips covering it. I'll probably just leave that; if it gets really cold I can slide the door down over it. The little house seems to be draft-free. I can't feel any wind when I stand inside it. I just don't want to over-do it and have it too closed up. It's about 4x6, DLM, 4 BO hens. Any thought/suggestions will be appreciated.
