My doe kidded April 7th. She has never had a full udder and now her teats have turned dark as well as the area around the teats. She is letting one of the kids nurse, but we've been feeding two, because she won't let them nurse. Could she have an infection or something? I've been giving her nutridrench. She has not lost her appetite and doesn't seem sick at all. But her udder just doesn't look right to me. Any help would be greatly appreciated.
