I got 9 ducklings last summer and am down to two pair of those this spring. I decided I wanted to make sure I had enough ducks so I ordered 10 females from Metzer's Farm. They arrived 2 weeks ago. I can't wait until they are all running around.
I have one Cayuga duck with my mixed flock and she is so sweet. It took a lot more work to make her friendly then any other breed I have had. So spend a lot of time with them...( like that will be hard!)
