well, shera
I used to breed ducks, they didn't start to lay eggs until they were between 9-11 months old! Mine were Rouens though, so I don't know if it is much different for other breeds. I now have a Pekin and a Black Cuyuga and they both started laying around one year old.
As far as the breeding, if you have enough water for them to swim in, the process is rather humourus. It isn't like chickens where the rooster attacks the hen, with ducks the male and female will "court" for a few minutes bobbing thier head up and down, then the boy does his this very quickly and then quacks funny and it's done! My kids ages 6-3 liked to watch

ducks are noobs.
Screw duck eggs.
Chicken eggs taste better
