for people who love the littlest dairy goats
The person who sold you the goats should have tattooed them. The breeder's tattoo goes in the goat's right ear, and the year and number goes in the left ear. Every year has a different letter -- this year is A; last year was Z; next year will be B. The breeder has to be the one putting the number in there though, because only they know what number is correct. If you just pick a number and put it in there, it might be taken by another goat in their herd, and the registry would reject it. Call the breeder and tell them they need to do it for you.
