im fairly new to backyardherding. i have two ndg does in milk, one kidding next month , and one alpine doeling kidding in two months. i think it is a good idea to get rid of problem livestock although i know it can be difficult. however, the well being of the entire herd (including your human tribe) has to be taken into consideration. personally i would not sell problem livestock. the perfect home is going to be your only selling option. i would have to consider the option of termination if the problem is really troublesome.
