Battery-cages are how 99% of big agri-business, or 'factory-farmed' chickens are kept, in amazingly cruel confinement their entire lives!
In mega barns........with hundreds of thousands (!) of hens crammed into small battery cages.........where they have less than 6 x 7 INCHES of space to "live" their entire lives; and endure horrific
conditions, unable to express normal chicken behaviors such as flapping their winds, dust-bathing, fresh air, sunshine, etc., etc., etc.......
Jeez............google 'factory farming'.....or 'battery caged hens'.....or watch the movie 'Food, Inc'.......or better yet watch 'Fowl Play'......and witness what big agri-business has done, and is doing to
living, breathing, feeling creatures................all in the name of profit!!
It's heart-breaking, and disgusting, and just so WRONG!!!!!!!!!!!
It's part of the reason why I am a vegetarian, and have happy, free-range chickens!
