Introducing Chickens to my Ducks???

[MysticalMom]

I have an opportunity to rescue 5 adult chickens ( hens) and give them a MUCH better home than they have now. I'm a duck owner and not sure how to introduce said chickens to my ducks. Will there be a lot of problems? If I decide to do this chicken thing, whats the best way to introduce everybody? My ducks free range in the day and are penned at night. I'd like to do the same with the chickens since that's what they're already used to. The chickens will have a separate pen.

Same question, different order. Have chickens, want to introduce ducks...
