Twins rarely survive, and often take the mare with them. If they do all come out unscathed, you're pretty much guaranteed to have very small and somewhat unhealthy foals.
Horses are flat out not designed to have twins. They only have enough room for one, so when two develop, they rob nutrients from each other. Sometimes one will survive, or be born ok, but the other will be sickly or more often then not die.
Twins should be avoided at absolutely ALL costs. It is a rather simple procedure to have your mare checked, and pinched off if the vet discovers she's twinned. Twins in horses are not cute, and almost always fatal for one of the parties involved.
Twins aren't born "identical". In my experience they're usually the same color, but with different markings. If they do survive, one is almost always bigger then the other.
I hope God tells her to smash her computer with a sledgehammer.
