I’ve limited experience compared to many, this is my 3 or 4th year at ducks now. My Saxony duck is a doll baby but very vocal! I don’t mind. Welsh girls both very very vocal but quite friendly. My Cayuga’s are very friendly, but a little more difficult to approach unless you have peas or meal worms.
