Herd Master
Not a goat, but I had a sheep who only wanted one of her twin lambs a couple years ago. I penned them both, and let mom nurse them several times a day, as I held her so she'd let her 'unfavorite' nurse. I went on the theory that 'you either take both, or you're not getting your favorite'. She accepted the other one a bit more each day, and was ok with them both by the end of the first week. It was a bit of work, but less than bottlefeeding would have been. Good luck!
