After a mare is covered, it will become pregnant. This takes 12 months to progress. On the 12th month you must call the vet and make sure your mare is boarded at an equestrian center. If you don't call the vet, you will lose the foal. From the 8th month onward, you can spend 50 Equus for an ultrasound in order to know the foal's coat, gender and breed in advance.
