NC has always had large scale poultry production. Holly Farms Chicken started in Wilkesboro in the 50’s and grew to be large enough to be bought out by Tyson or Perdue (can’t recall which) in the late 80’s or early 90’s.
Big chicken killed the small producers.
I sell a lumberyard in Goldsboro who has been selling to several of these chicken house builders for the last ten years. It was huge business for them during the Great Recession when there was no other new home construction going on.
We also sell Hog Slat over in that neck of the woods.
