Many people raise them together; however, I choose not to. My ducks always have been a little aggressive to the chickens and they have got into some scuffles with the roosters. Another thing to consider is the water issue. Ducks make a mess of the water, where the chicken water stays pretty darn clean. My ducks also just have a dog-house-type shelter in their run whereas the chickens have the ramp up into the house complete with nesting boxes and roosts. So, it also depends on what your set up is like.
I will say though, that when we let them ALL out of their runs for some supervised free-ranging in the afternoons, there usually aren't any issues. They just stay away from each other and if the the two groups get too close, the ducks usually let them know they should leave their area. LOL
