CLINTON — The roof of a barn collapsed under a heavy snowload at Caverly Farms overnight.

Four cows are dead and 80 other cows were rescued from the barn, said Brian Caverly, an owner of the dairy farm on River Road, who discovered the collapsed roof around 3:30 a.m. today.

He said four cows that suffered broken legs and were put down by a veterinarian.

Farm employees were cleaning up debris this morning. Caverly said it was “remarkable” that 80 cows made it out alive considering the extent of the roof collapse. Those cows were relocated to other barns at the farm.

The family-owned dairy farm, which sells its milk to Hood, has about 425 milk cows and 400 young stock, according a brochure provided by the farm at Open Farm Day in July.
