If anyone was curious about penning up farm animals, Red51 stated (in a joking manner) on Steam that you could technically use a rolling pin to chase a cow or pig towards a penned area then block off the exit. Ofcourse in the future there will be better ways to domesticate animals but I mentioned this to a youtuber who actually pulled it off!
BTW, Radioman has an awesome lets play series. The action begins at 10:40 incase the link starts from the beginning.
