My first Nigerian doe that I bought last summer had two kids this spring, a buckling and a doeling. I sold the buckling as a wether pet and was planning on keeping the doeling until I discovered she had an extra teat. I decided the best thing would be for her to be a pet only and sold her without registration to a really good pet only home. My doe doesn't have any extra teats and neither did the buck she was bred to. I'm wondering if she shouldn't be bred again, I don't want this to happen in the future. So I guess I'm wondering if this is likely to happen again or is it pretty rare? I use my goats for milking and would love to eventually get involved in showing. Any advice?
