I knew something wasn't right, called the vet several times and kept waiting a bit to see if anything would happen, per instructions. I finally called and said, "This isn't right. She should have had this calf by now!"
The vet came out. I asked if my instincts were right, and he said yes. He and Androo spent over half an hour removing a huge dead calf from her.
I am so sad. Skipper Princess is okay, but she is searching for her calf. It breaks my heart.
