Okie Dokie, so since we moved from Phoenix, I have switched the goats over from Purina Goat Mineral to Cargill Right Now Onyx. It smells pretty terrible, but my girls are looking GREAT! I have many girls who are black, and they had started turning red in their hind legs due to deficiency, turns out the copper in the minerals they were getting weren't chelated (attached to other elements to aid in absorption). The Onyx mineral is the only one I've found with chelated copper. Now they are all looking great, full tails and black legs. Anyway, I highly recommend Onyx to anyone with fish tails and red hind leg hair Anyone else use this stuff??
