This made me laugh. My daughter had 10 very tame sheep. When she let them into her back yard to eat grass, they forced open the screen door and came in her nice neat house. The whole herd wandered all around the house, looking at everything including the bathrooms. When she finally got them to leave and just eat the back yard grass, they spent their time on the patio staring in the windows and occasionally licking them! From then on, whenever the grass needed "mowing", the sheep would eat some and then gather at the back windows and look in and baa. They would come in if they ever got a chance and she needed to keep the door locked!
There were coyotes in the vicinity and maybe the sheep thought that the house was a much better place for everyone concerned!
