Having worked for the SPCA of Texas in the past and my father having worked in Animal Control / Non-Profit Humane Societies for over 30 years - I can tell you that without a doubt the majority of these videos are faked / staged. I've been to over 3 dozen cattle ranches in Texas, a couple chicken farms, and more. Sure the are a little crowded at feeding time, but same can be said about a bunch of students in a cafeteria.
PETA and the rest of those morons need to be put in their place and leave it alone. Farmers / Ranchers aren't going to mess with their livelihood.
