I am wondering what others might have in their duck runs to keep their ducks occupied? Maybe a silly question, but I just recently split a section of my chicken run off to keep the ducks separate and I am worried they are bored. They have a little duck pond to play in, but the rest of the run is just sand/dirt. They have a duck house to run into if they want, but compared to the chickens run, theirs is empty. Any ideas what I could add to make things more intersting in there for them. I can only provide so many treats before I have 50lb ducks lol. Or is that pretty much all ducks do, eat, swim and sleep?
