Broody ducks?

[duckboatprincess]

I just have a quick question. Will domestic ducks sit on their eggs?
I have two pekins, four rouens, and 2 fawn and white runners. I know what the pekins and rouens were born in March or April (I can't remember when I got them). The runners are a bit younger. Their primary wing feathers aren't fully developed yet.

I just had one of my Pekins go broody. she was sitting on 13 eggs and hatched out 11. She is just over a year old.
