Is this the right stuff. I have tried the St. John Wort Capsules that looks like ground herbs with distilled water and it doesn't appear to be helping.
Two on my best Roo's has paralysis on the left side. The entire flock has been wormed and treated with Corid after losing 4 of my best pullets with similar symptoms. So now my best Cream Legbar and Araucana Roo's (hatched in April) can hardly stand but still has a good appetite. What I have read on this thread is giving a little hope.
I would think that Hypericum may help with some disorders, but Marek's is a cancer, and neuro symptoms are caused by tumors in the nerves. I don't think that there are medications that cure cancer or tumors and they continue to grow and spread. You have lost 4 chickens to paralysis, now 2 more show it. I myself would be searching for something that will help, it seems like vaccination is the only thing right now.
