"An HSUS undercover investigation conducted in February and March of 2012 revealed a range of severe problems, including inhumane treatment of animals, at a Manheim, Pa., egg factory owned by Kreider Farms.
Of the nation's 280 million egg-laying hens, Kreider cages approximately 7 million at its four Pennsylvania facilities. Pennsylvania is the nation's third largest egg-producing state.
The following problems, among others, were documented by the HSUS investigator.
Birds were severely overcrowded in cages more cramped than the national average;
each hen received only 54–58 square inches of space on which to spend her life.
Injured and dead hens, including mummified bird carcasses, were found inside cages with living hens
laying eggs for human consumption.
Hens were left without water for days when a water source malfunctioned, causing many to die.
Hens' legs, wings, and heads were found trapped in cage wires and automated feeding machinery.
A thick layer of dead flies on the barn floors caused a crunching sound when walking on it."
