I have a bird with Marek’s symptoms (blood test pending). She has been having difficulty with progressively poor balance and leg weakness for over two weeks now. I have read many threads regarding improvement of symptoms using St. John’s wort and/or hypericum however there seems to be a difference in the two that I am confused about. Many of the posts seem to reference a homeopathic formulation of hypericum which I cannot find. What I found locally is the St. John’s wort 300 mg capsule (states active ingredient is hypericum perforatum). Is there anyone who can tell me what the appropriate dosage to try would be for a 9 week old 290 gram bantam?
