Hello All, I would like to design/build a small barn for myself and am wondering what type of floor do folks think is best for the cooler climates (Central Maine â 4b). I plan for it to be home to dairy goats, pot bellies and maybe some sheep (not sure about the sheep). Donât think anything like a dairy cow or horse, but who knows down the line (can you tell we are a little new to this?). Should I be thinking a natural earth floor or concrete or something else? Thanks in advance.
