Hello. I have been keeping a small tribe of angora goats for a few years now and we used the "Molly's Herbals" worming formula for the first time this past summer. We only needed to worm our goats once all year, which was a drastic improvement on the previous year. The formula included black walnut and wormwood. We will continue to add pastures in order to increase our rotating and reduce our need for such worming, but until then I am interested to know if there are folks out there gathering black walnut and feeding it as a wormer.
