I was curious, four of the goats we've rescued from the auction have tattoos in their ears, on both sides. Does this mean they are registered? Three are alpine, and one is a toggenburg. And if it does, is there a way to find out info on them by looking up their number? Also, I just rescued a pygmy doe yesterday from the auction. She's about 7 years old judging by her teeth, and I found after we bought her that she has a tag in her ear, says US and then on the inside it says WA and then a number.. does this mean she could be registered?
