Hi, I am after some advice about keeping ducks. I would like to keep a pair free ranging in my yard. I am after any advice you can offer about breeds, set up, etc. I live on just under 1/2 an acre in town. So I would like a breed that isn't going to make too much noise. I am not interesting in eating them but to have them for eggs and pest management. Any advice would be a great help. Thanks.
