This is my moms mare and and we argue back and forth on whether or not she is in foal. She has had two foals in the past. She never gets "big" when in foal. She would be due the and of June if bred.
That would be my sorrel frame overo mare. She is the biggest pest I own. I can never go anywhere with out her. I have her mom here for breeding to Boo right now as well, except he isnt to keen on her.
This mare was less than 1 month from foaling but to me did not look preg. She foaled 3 weeks later a very large colt (22" and 30lbs at birth). The tip off was she was bagging and the foal movement.
