Title says it all, I guess 
I have a large chicken coop with attached run that has plenty of extra space. I'm getting 4 or 5 ducks in May and have a 4x6 ft duck coop under construction. It would simplify my life a ton if I put the duck coop in the chicken run which has multiple layers of protection against our local predators-coyotes, hawks, etc. My main concerns are this-
1. Will the ducks empty my chicken water? Their waterer is a 20 gallon rubber trash bin with horizontal nipple waterers. Will the ducks go in their coop and drain that of water?
2. Will the ducks and my rooster coexist? I won't be getting any drakes and I only have the 1 rooster. Anything to be concerned about there? Would he try to mate them?
If it is going to create more problems than it solves I won't do it. I'm just trying to avoid the hassle of setting up another airtight run or worry about running electricity somewhere else.
Look forward to your thoughts, thanks!
