In the next building, the hens weren’t as limp and silent. But they still weren’t exactly sprightly. Our guide said that after a couple of years in the battery cages, the hens are so depleted, "we can't give them away." No wonder, the air was thick with fecal and feather particles, like it was snowing. The cages were arranged in vertical tiers so the crap from each cage rained down on those below. Many of the hens had gray splats on them. Under each row of cages was a deep trench filled with an 8-ft-deep pile of feces, like a long gray mountain range. The pile is removed only when the hens are replaced, every two years. That explains the stench. For more about this charming tour, see Veggie Revolution.
