Melissa Culverson posted two photos to public Facebook page One Day Closer to Rain (Drought), but there was something unusual about the newborn male.
The black calf, which Melissa called a 'miracle drought calf' has an extra leg, attached to its back.
Commenters suggested animal may have a genetic condition, or that the leg belonged to a twin that had been absorbed by the calf in the womb.
Melissa said she hoped the animal would bring good luck.
