bikkurikun: I guess these are baby roosters. Possibly the shredder at the chicken farm broke down, so they had to dump them somewhere else.

Every year about 200 million male day-old-chicks are being tossed in the shredder alive.

i don't know about shredders, but my uncle's rendering plant would receive several 55 gallon drums of suffocated male chicks a couple of times a week. The 'sexers' would look at the chicks, toss the males into the drums, one after another, until one layer snuffed out the previous layer. When the drums were filled a lid was popped on and another barrel moved into line. This was in the 1960s, so maybe now they use shredders. Circle of life, people; circle of life.
