So I just got chicks and ducklings. I know it will be a while before they're big enough to be outside and handle the cold etc but I'm asking in advance.... Due to configuration I have to build a run that goes up over the door to my lawn mower she'd and down the other side into the big run. I know it'll need a solid bottom and rungs across for grip and obviously wire on the other 3 sides. I'm quite confident that the chickens can do it as apparently they climb. But....can ducks do it? How steep can they climb?
