I know it’s currently summer but I’m thinking ahead about how I can make my shed warmer this winter. The pigs have already spent one winter in there but it was so cold I worry about them being outside again this year. I’m just looking for peoples ideas on things I can do to keep it warm. The walls and roof have polystyrene on them for insulation and that is covered with another layer of plywood. The hutch which is in the shed itself has foil insulation on its roof and walls and a second layer of plywood. They have many cosy beds etc. So yeah I would love other ideas please if you have any
