I have six girl Cochens and One Rooster. I am thinking of six female runner ducks for eating ticks. We have a big issue these days in Central Texas. Good plan? Also, do you think they will get along with the Cochen's and vise versa? and we have a creek 30 yards from coop...will that work for their water needs? Will they poop up the creek? Appreciate suggestions. And the eggs are yummy I hear? thank you.
