The triplet calves born on the Christopher farm near Letcher, SD, are truly a once-in-a-lifetime occurrence.

So excuse John Christopher if he couldn't believe his fortune when he found three healthy calves in a pen last weekend.

“I was just in shock. I just couldn't believe it," Christopher said. "It's something that we're still wrapping our heads around. I mean what are the odds?"

Russ Daly, South Dakota State University (SDSU) Extension veterinarian in Brookings, says the number most often associated with a cow having triplet calves comes from a 1920 study that says it is a 1 in 105,000 chance.
