I have a cow that is 2 weeks overdue with her third calf. She was AI-ed so I know her exact breed date. She is slowly showing signs of wanting to calve - softening, developing her bag. I just don't know if I should be concerned that she is late. Her first two calves were right on schedule. She was bred to an Angus, she is an Angus cross, about 1200 pounds. She is not showing any signs of distress.
