My guess is wetbacks.
We have a winner!! Add in a few vegans to the facility to do some high def killing and do all the filming, especially the up close, dying hen vids.
I've had laying hens and roaster hens as well as quite a few roosters for years. Have one in the back yard now. I even have a Silver Seabright hen in a cage in my bedroom. Had her as a pet for years. But I eat chicken often. And I eat more eggs than my doctor would recommend.
What I see in this video is more confirmation of why we need to remove and BAN these Mexican savages and the employers that hire them. They have no more regard for an American's life than they do one of these harmless chickens...
Slinging boxes of chicks onto a conveyor belt is both cruel and a destruction of the employers property. They are extremely fragile. That would be like throwing kittens out the back door to see if you can make them hit the fence.
