I haven't moved in yet... 19 days and counting... but the barn looks like it will be very drafty in the winter. I can put boards up over the wooden wall, but I don't really know how to draft and predator-proof the stone wall's holes. The layout of the barn is that there are three large stalls on the right side and the left is all open. If we are able to herd the chickens into one or more of the stalls, I don't need to worry about the stone wall quite as much, I don't think? I was considering putting a freestanding coop in one of the stalls to protect them during the winter, but I don't know how practical it will be or how expensive it would be to make. Any suggestions for upstate NY would be appreciated! This is Saugerties, NY, if that helps figure out what the weather will be like.
