Do any of you use Hoegger's Herbal Wormer and Tonic? If so, what do you think of it? Does it get the job done? I haven't learned yet to check out worms in berries under a microscope, but I want to sometime. Do you like to use anything else in addition to this, like once a year, that is a chemical wormer? I'd like to hear your thoughts, as this is the only wormer I've used since starting with goats almost 4 years ago.
