Oh Yes, ducks are the best!!! I love mine too! they are much smarter I reckon than chooks.
Theres lots of beginner duck threads here showing ponds etc.
Go with good ol muscovies for peace, I have white mallards and the girls quack loudly but its a cute donald duck sound.
I have my 2 young mallards sleeping with my silkies at night, they love to snuggle under them, so cute.
They range with my chickens and unlike their parents they havent managed to destroy the water yet.
If you want ducklings, get a drake and duck(female) or if you just want eggs for cooking, get 2 girls.
Have fun.
