Quote: I'd think as Big Dan suggested it would act through burning. ACV would also afford some protection. Here's some snippets I found:
Quote: Anyway, I found that when they're down (which shows you which ones are weak to it, as some are immune naturally) then you give raw (not homogenized or pasteurized) cow's milk with the fat skimmed off the top and a flat tablespoon of preferably raw honey, mixed together in a cup. Sometimes you need to dip their beaks in it but mostly by the time they're down, they've been fasting for some time and their diarrhea is bright yellow and khaki, the disease has run its course, and they will eagerly drink the cupful. If you don't give the milk/honey cure at that point they'll die, it seems to be a small window of opportunity for those weak enough to go down with it. You can give them more but basically that almost always gets them back up on their feet and healed within 24 hours and I don't advise giving them the milk/honey cure for longer than 48 hours at the very most.
 
Best to avoid grains and cereals, give rolled oats and maybe millet at the most, a fresh green diet preferably containing raw garlic/onion/dandelion is best for the next few days to let their livers and guts heal the rest of the way. Just let them freerange, I reckon. This almost always gives them a lifetime's immunity and they will go on to breed tougher stock which in turn will produce offspring that probably won't need treating at all; however I won't vouch for vaccinated stock as they seem to reinfect constantly with simple diseases that are supposed to be once-offs. Don't give the cure before or after they're showing the severe diarrhea and preferably laying down because then you delay or prevent the cure; also giving it for too long after they're back up on their feet can have weakening effects as their liver is unable to stand the steady fat intake. It's like a miracle pill at the right time though! Best wishes.
