The most noise they make is during mating season when the male is trying to mount the female. The females are slightly smaller at 8-12 pounds. If you live in the city, you may want to consider a smaller bird. We also raise Indian Runners and Mandarins as well as Red Golden pheasants. We have found the Mandarins to be almost silent, although they will make some noise when we are trying to catch them for examination.
Mandarins are monogamous which means that they mate for life.
No matter what kind of birds you choose, all ducks can benefit from a pond or kids swimming pool. Some ducks will actually mate on the water, and they are always looking for a place to take a bath every day. You will also want to give some serious consideration to housing the birds. Since you live in the city, you will want to build a pen that has fencing buried two feet underground and that goes 6 feet above ground. You will also need some netting for a roof.
