OK not imminent but I know I want to add call ducks and probably some bigger breeds to my going chicken operation. I would plan to build or add on to the chicken run so the ducks have a space kinda to themselves especially when free ranging is not happening. like deep winter or if we are going to be gone a day or more. What I am wanting is concerns of cooping and or running ducks with chickens. What specifically needs to be added and the least expensive easiest to maintain specialized equiptment needed such as I know I need to provide water the ducks can swim in it needs to be filtered or changed out. I need to have it available even in the freezing months how best do I do this. What kinds of problems may arise when runing or free ranging together. etc etc. I'm sure I'm not the only one to get the duck itch after having set up for chickes so what did ya learn what suprised you what do you wish you had know before hand. Thanks.
