I have chickens and rabbits, but have heard that ducks are more efficient keepers than chickens. Are ducks noisier than chickens (my hens are godawful loud most of the time, but I don't want to piss off neighbors or hubby TOO much)? What do you guys think? I have a small fenced yard to keep them all in (rabbits in raised hutches, chickens in a small coop), and I recently started selling the chicken eggs but they can't keep up with demand (I only have 5 laying hens and some chicks right now). I have heard that Khaki Campbells are high producers, and excellent foragers...what are the pros and cons of duck ownership? Should I consider replacing my hens with ducks, or is it possible/beneficial to keep both hens and ducks together? Thank you!
