Advise on caring for ducklings
- Overrun with Runners
From what I have read, it depends on the ducks and the chickens. Drakes (males) can be a danger to chickens if they try to mate with them.
If they are all females, it could work out better.

Here is a like with great advise http://www.backyardchickens.com/t/750869/raising-and-caring-for-ducklings#post_10611711
As for keeping ducks and chickens in the same pen that will determine on what breed of chicken you have[some chickens can be very aggressive towards ducks]I have a couple BA's that will chase and scare my ducks, and if you have a drake. as Amiga said Drakes can try and will mate with chicken hen if they don't have enough female ducks to keep them happy [rec. 3-4 female ducks to every drake] So I would not rec getting ducks unless you can keep them in separate pen or only get females. I have chickens and ducks and drake but my drake has plenty of ducks and has never shown any interest in mating with a hen. They free range in a large fenced property too. But at night they all have their own sleeping quarters.
