hey folks! any idea if poly-tonine a complex vitamin powder is appropriate for ducks? and if so, in what amounts? i'm thinking my ducks could use a vitamin boost. the package says it is for "pullets, laying hens, broilers, and turkeys: as an aid in the prevention of vitamin deficiencies." i am guessing that the manufacturer is thinking of chickens, not ducks, so i bet the dosage would have to be lower than the package advises. thanks!
