Tyson Foods does the same.Go look at the torrid criminal life story of Don Tyson (including murder), that was promoted under the Clinton's (after Clinton became governor of Arkansas, to take over the chicken industry in the 80s in the SE where chickens are commercially grown. Same thing, they get monthly "inspections" by Tyson trained specialist and have to adhere to the same crap. The farmers used t be able to run very small scale farms and they were shut down the same way. Now typical chicken houses have 15-20 thousand birds per house and many have a dozen "chicken houses" also attache to mortgages, etc.
Dairy's were also done the same way in the 70's.
