My doe Phantom is due on 3/31. This morning, I noticed her udder had filled quite a bit. However, it is not strutted. Also, one of her ligs has disappeared, and the other is very soft. I've noticed she's being very vocal and has spent a few hours up at the goat shed, not out with the other 2 goats & sheep. Could these be signs she's getting ready to go very soon? I don't know much about her kidding habits, only that she was usually unassisted; I just bought her last year.
