I have heard from so many people that individual states require an identification means in order to sell stock, like a registration #, a tattoo, an ear tag or a microchip. I would be willing to tattoo my goats, but i cannot find anything online for identification rules in Michigan! since my goat's arent registered, i can't find a place to get a herd tatto number either. Is there such a thing? it seems like there would be, because there are alot of tattooed mutts for sale, or unregistered animals it seems like. what is scrapies by the way? that came up soooo often during my searches. Also, i was wondering what kind of tests I should do here. Daisy came with a metal tag in her ear, from a TB free herd, and I have seen people advertise about being "cae" (and something else i can't remember), free. where do I get these tests done? I have asked that before, but i dont' remember what people said.
