Hey everyone! Needing some insight on adding a duck enclosure to an existing chicken coop. We will have 2-3 runner ducks in here. All chickens and ducks freely free range during the day so this would just be for nighttime. We have an automatic door. So far this rough estimate is about 4.5’ x 4.5”. Top will Hinge for cleaning and egg collection if they are female. Was thinking to leave the rectangular section circled in green as ventilation? But I realize that is the poop catch area for the chickens. Or I could do some side windows and close that area off. Any suggestions welcome!
