Can you give us an idea which would treat what chooks.Good to hear, wonder what happened? Might never know, but sounds like you got some great advice here.
Just wanted to say, about the charcoal, it's a lifesaver for sure, but cannot treat ALL toxins. Some cannot be treated, some can be treated in other ways. Vitamin C in mega-doses can treat some things charcoal cannot. Another great one to always have on hand for your animals.
Best wishes, hope she goes from strength to strength.
