Over the past couple of weeks, I've been watching live web cameras on MareStare.com. It's been fascinating and very educational. They have messege boards for discussion, and also to help keep watch on pregnant mares, before, during and after their foals' birth . It's a good community of people helping each other.
I will warn you that the live births can be graphic and stressful to watch, at times. (It might also keep you up late at night!) There have been some sad outcomes, but most are very happy and heart warming. Give it a try, if you're game. I'll leave the link on my permanent sidebar.
