My chickens often come to the door of the back entrance/ utility room where I keep a small supply of chicken food. Ini Min has made a habit of coming in when the door is open to poop on the mat. And both Black and Pearl come in once or twice every year when they become broody to see if they can find a nice breeding spot in the utility room. Katrientje only comes to the door to check if there might be treats for her.
