Looks fine, Kay. If she hangs out in the front left corner, will we be able to see her? She looks great--more filled out than last year? Her backbone is more covered? Or am I imagining things? She's the mare you have a hard time keeping weight on despite lots of grain?
One thing both my mares did that was so telling they were about to foal is to have frequent poops. Both had several piles in a very short time, like 1-2 minutes apart. Right afterwards--they started labor.
