I'm sick of these videos. You have no idea who was filming this, where they were filming it, and for what intent. This could have been a film of some poultry farm in Mexico.
Things like this are circulating across the internet all the time. It serves us best not to believe them.
Fast food places may not go the extra mile for thier chickens, but if Wendy's kept thier animals like this, they would have been sued a long time ago.
