Do you know how to check a goat's ligaments? It is the only sure fire way to knowing exactly when your goat is going to kid. That's how I always check mine and they always kid within 24 hours of find their ligaments 'gone'.
Yep, that's part of what I mean by becoming soft. The three closest goat's (Dmetri, Ruth, and Esther) ligaments are all soft, but not gone. So, a few days yet!
