So this will be our first central PA winter with our chickens and ducks. They have a wooden coop with an attached run. During the summer the chickens always go up in the coop to roost at night and the ducks stay in the run. We’re thinking of putting plywood around the run for the winter. Will this be sufficient? Should we use the heat lamp in the coop? Or the run? Or both? I know they can be resilient birds but I want to do right by them. And being this is our first winter we want to make sure we get it right. Any advise is welcome. Thank you!!
