I am assuming you want to know how to keep your chickens from eating the ducks food and the ducks from eating the chicken food.
First ands easiest way is to keep the ducks separate/feed separate.
If this is not possible and they free range together try placing the ducks food in an area surrounded by water, adult chickens by nature don't like to get wet, ducks do. If the duck food is only accessible by crossing a water barrier then the chickens will stay out of it.
The best method is distillation.

Yes, it will not hurt them. Ducks are often kept with chickens and they share grains. Keeping the chickens on a regular diet of duck specific grains is not a good idea as the nutritional needs of the species are slightly different. You will not get your best growth and egg production from hens fed this way.
Filtration is the best method.
u can tell buy color and size
Allow the water to evaporate, leaving behind the salt would be effective for separating salt and water in a mixture.
Via filtration, through a 0.45um glass fibre filter.
Yes. if you want eggs to eat get females. If you only want pets get either.
Three types of farmyard fowl are chickens, guinea fowl, and ducks. The chicken may be the best known type of farm fowl. However, there are different breeds of chickens, including Wyandotte, Andalusian, Australorp, and Java.
Yes and no. First off most will tell you it is best to have an odd number of roosters in a flock. Not an even number. Ducks & geese are messy birds. So they make dry bedding wet which chickens dislike. Hope this helps!
