Well, for Belle's sake.... thank goodness for small foals!
Duchess, I looked it up again in my horse book:) and it says normal gestation is 342 days. If you've been figureing 326 that may be why your foals seem late.
I think the 342 is right, at least for Belle, she hit that mark right on with Dot.
If I figure Belle's date at 326 that makes her due, April 27.
