I use the one from Morning Bird. It comes powdered, in different quantities.
This is the only one I've tried so I don't know how it compares to any other brands that may be available.
The "recipe" is 1/4 teaspoon to one quart of water for this particular brand.
It also says you can mix it in with fruits/veggies or softwood.
And as I just learned, you provide it for as many days as your birds were on medication
(the instructions on the container don't specify that). Hope that helps
Others on here probably have experience with other brands.
