With my ducklings looking more like ducks these days, I really want to let them out but I'm sooooo afraid they're going to take off and I won't be able to find them. What do you all suggest? Should I get a large "run" or a pen to keep them confined or should I not worry about it and let them out?!? I do have a pen we used last summer for the bunnies. I can always put that up around their house and take the run off for now. Give them some more space until I can expand that run with another crate or two. I'm just torn as to what to do with these guys. My goal is to have them free range.
