Cruelty to animals in factory farming

Overcrowding (causing severe stress), inadequate space allowance and immobilization of animals (causing malformations), tethering, use of slats, inadequate lighting, use of wire mesh flooring for poultry and lamb, beak clipping, use of spectacles and dubbing of poultry, inadequate feeding of white veal calves, inhumane slaughter of unwanted male chicks (suffocation in airtight barrels, drowning in boiling water, boxes connected with a car exhaust pipe), are all examples of cruelty to animals in some factory farming.
