I have 3 does that recently kidded. They all seem to be copper deficient. I copper bolused black doe December 3rd 2020 and gold doe November 20th and red doe around the same time.The black one has had her black coat be red for like all winter so is it they just haven't shed their copper deficient coat yet? Their noses are balding is that a copper or zinc issue? Their minerals are sweetlix meat maker.
