Yeah, I can just see it. This would be classified as a multiple teat. The fish teat I was referring to actually is a teat that looks like a fish's tail. One teat with 2 different smaller teats at the lower end.
We have spoken to both breeders - those we got our original does from and the breeders that own the sire. Our does' line appears to be completely clear. The owners of the sire were going to check and see if any of his other kids had the trait (this was his first year so there aren't that many to compare to). They are willing to refund our money or offer a free stud service this fall with a different buck. I'm glad that they are trying to make it right. It's just incredibly disappointing on several levels. We had hoped to keep her to replace one of our milking does. And unfortunately because we didn't notice the issue right away, we have allowed ourselves to become attached to her, making slaughtering her that much more difficult.
