"Battery hens" is the term used mostly in the UK. Here in the U.S.A., we would probably call them "factory chickens." These are hens in the chicken factories producing eggs for the consumer. In cages. Stuffed several to each cage, and never leaving those cages until they die or are taken out to be culled, because their production has fallen. Most battery or factory hens are only two years old, maybe three. But they have never touched ground, never run free, never had a treat in their lives, and all they do is lay eggs. That's their purpose in life.
Hi there! New here too, actually new to the whole chicken thing.
I've never heard of a battery hen, until mac in abilene and gryeyes explained it in your reply postings, thanks guys! So, are you rescuing one ore are you just thinking about it? Are you keeping chickens for pets, eggs, food?
