Vicknick, I know this thread is older, but I have a young pullet that is showing signs of Marek's now. And I'm wondering how yours did with the Hypericum? I'm going to just give it a try because it can't hurt! But I was wondering if it helped.Update - Gave the droopy one a few drops of Hypericum last week. She's not droopy anymore. I've been watching everyone carefully, and aside from a few sneezes now and then, they're all doing well. I have antibiotic on order, supposed to get here on Tuesday, for Myco symptoms, I'd like to clear that up totally, but have been weighing each in my arms every day, so no weight loss can sneak up on me. So, for now, status is - keepin' on keepin' on...
