Back when barns were uninsulated wooden structures with usually a hay loft above. The only heat came from the animals. More animals more heat. Straw was used for bedding. Most of these barns were warm in cold weather.
For the OP; lots of straw bedding that is dry and more animals or a smaller enclosure for the ones there are.
