I heard that to sell your goats you must tag them. I know that you must tag them if you plan to sell them at an auction, or they can only be sold as meat. This may just be in michigan. I have always thought that tagging in a small herd is stupid, and even stupider if they are pets, and stupidest to tag goats because they always seem to get their heads stuck and thier tags torn out, exc. I do have the tag for one of my goats in my closet, never had it put in, but still own it. When i got daisy, she had the metal tag in her ear, and it was all infected so we took it out and it healed well, only now there is a rectangular hole in her ear still. we threw that one away.
