We are just getting our first flock of chickens together, and a friend has offered us Cayuga ducklings. My daughter is crazy about the idea, and I'm considering it. Can ducks free range with chickens? What is the smallest number of ducks to keep? Would they be happy in a walled off extension of our chicken run? We have acreage, but I only feel comfortable letting birds free range in our 1/2-acre fenced backyard, and they need to live fairly close to the house where we can hear them. The predator situation is pretty intense. Everyone would have to get along in close quarters. I would appreciate any opinions or advice. I don't know much about ducks. Thanks!
