So a few instances have occurred where I awoke to a lovely day of my cows and goats on the roof of their home. Some get excited enough about food to jump on down, but others just chill on the rooftops. I think this may have to do with me having put items in the buildings along with beds. This may be causing over crowding. I will post an image of my barn layout + both instances of them being on the roof. I have since removed the two feeders and two watering troughs from the chickens house. They no longer pop onto the roof.
