The horses that I used to care for got two flakes twice a day, and pregnent and nursing mares got three. But sometimes the rule is better to give too little than too much as far as grain goes if your unsure.
I agree:)

Thanks Beaker, my mare with foal and also my pregnant mare are both getting 3 flakes now and also the mare and foal feed.
Our horse Misty is doing good now, no sign of any problems and eating/drinking and "going" just fine. No sign of colic.
