Animals put out heat. To take advantage of their heat (and keep people from stealing them), people built housebarns. I don’t need one because he puts out a lot of BTU‘s at night.
They never really caught on in the US, but they are all over the Canton of Fribourg (near the town of Gruyeres). I love them.
P.S. Those of you who play Farmville, please let me know if you can really purchase a Swiss Housebarn. Muchas gracias…um…er… Merci beaucoup.
