I have a mixed up breed of chickens 5 bantams and 2 polish regular size hens, I also have 2 Khaki Campbell ducks male and female. Ducks as I have learned are incredibly messy, chickens no so much. I am having trouble trying to figure out how to keep clean water for the chickens the ducks could care less. I have tried poultry nipples even going as far as picking up the chickens and sticking their beeks on them, they still have no clue. I took out all other water access and they just got thirsty so I felt bad for them and put the other back in. All my chickens let me pick them up and follow me around the coop. The ducks follow but don"t like to be picked up.
