Dr. Ron Hatcher and his wife Elsie have been breeding Rocky Mountain horses for 15 years.
"It's a breed that was originated really in Eastern Kentucky around the turn of the century," Elsie said.
Elsie said they were in love with the Rocky Mountain breed the fist time they laid eyes on the horse.
"That's what we breed for people. Friendly easy to be around the horse," Elsie said.
The very first Rocky Mountain horse the Hatchers bought recently gave birth to a set of twins.
"Very rare that twins survive in horses we understand," Elsie said.
When they saw they were having twins, the Hatchers became concerned about the second horse.
"When we realized that we were having a second, that we were having twins with the delivery of the second horse, we immediately called the vet," Elsie said.
Once the Hitchers called the vet he warned them of the slim chances the second horse would survive.
"But when he got here he was really surprised that they were both up and nursing and that they were about the same size."
Now that the horses have passed the three week mark, the vet said they should be in the clear.
"They're gaining weight and the mother is loosing a great amount of weight, she seems to have enough milk for them so we feel we are over the danger of twining," Elsie said.
The University of Kentucky is currently conducting a study on another pair of twin horses born in Richmond, Ky., earlier this year. They will also be coming to the Hatcher's farm to study their twins.
The researchers have determined the set from Richmond is fraternal.
The Hatchers are anxious to see if theirs are too.
