WAUBAY, S.D. (KSFY) -- Did you know it's a 0.04 percent chance of having twin buffalo calves for a herd?
This rare event has happened at the SWO Bison Farm near Waubay, South Dakota. Although it's something unique, there is a catch with the twins being both male and female.
"The bull calf puts off testosterone, which causes the heifer calf, she will not be fertile so she will never have a calf," explained Karena Miller, the assistant manager at the SWO Bison Farm.
The female twin was found all alone and was a surprise to everyone.
"I guess I never imagined such a thing, but it happened. We thought it was a white buffalo, but it ended up being twins which is awesome," said Stacey Miller, a buffalo tech at the farm.
On Wednesday, the female twin received a blessing with many of the Sisseton Wahpeton Sioux Tribal members joining. Those in the younger generation made up quite a bit of the 100 to 150 people at the event.
"Which is encouraging for us to see our youth. They can carry on these, the ways of our Dakota people," said Dave Flute, chairman for the Sisseton Wahpeton Sioux Tribe.
The twins were the first calves born this year to the genetically 100 percent buffalo herd.
"Culturally, it's a message to the people and it could be bad or it could be good. But, we're hoping it's good and we'll take it day by day," said Miller.
While the female twin stays inside to bulk up, her brother is out in the pasture with the others. She won't be able to rejoin the group until she's at least 6-months-old and able to fend for herself. She's also nameless right now, but tribal officials are taking suggestions in hopes of finding that perfect name.
