Yes, it's true. These sheep were originally purchased in 1968 from a wealthy Pittsburgh philanthropist who has been experimenting with Big Horn and Dall varieties. He wanted to breed animals that could survive and remain healthy in the wilds of the Pennsylvania mountains. By 1968 he had succeeded, but has lost interest in continuing the project any further.
Our location is in west-central Pennsylvania. The elevation averages around 1700 ft. above sea level. Our winters can get as cold as 20 below zero and our summers can get up to 100+ degrees. These factors could easily be handled by pure bred Bighorn and Dall sheep, however, the dampness of our climate and low elevation in this eastern area causes pneumonia in pure breed mountain sheep. Such animals cannot live here. Our sheep are not pure blooded but specially bred to survive in this environment. They are approximately 7/8 pure Bighorn and Mountain Dall sheep.
