A blogger has posted photos he took inside the Jentzch Mink Farm, in Medford, Wisconsin.
According to the poster, he was driving past the farm and stopped to talk with one of the workers, who showed him the inside of the farm.
A member of the Jentzch family, Bruce Jentzsch, is also listed as a contact person for the nearby Central Mink Foods, a mink feed supplier for Wisconsin fur farms.
These are the photos:
