Well said, Ribh. There are two extremes in chicken keeping and a whole gamut of the spectrum between them.
On the one extreme, you have the commercial industry, which only thinks of the welfare of the birds when it applies to production. On the other extreme, you have PETA, who think all domesticated animals are an abomination and slaves and should not exist.
A little less extreme, you have people on BYC who give their hatchery hens a good life but cull when the production goes down. The other side of that, you have people who keep games or semi-feral tribes that live and replicate themselves naturally, as Shad's did.
Most of us are going to fall between somewhere. Hopefully, we learn to think like a chicken and give them the best life we can. What a small and sorry world it would be without a possilbity of a connection to animals. What did Chief Seattle say, that humans would die from a great loneliness of the soul?
I came at chickens with a mentality from the dog world. I read on here for a year before I acquired my first pullets. Coming from dogs, I immediately knew I was going to go to a breeder instead of a hatchery (which my first instinct was to equate with "puppy mills for chickens," whether that is fair or not). I didn't know enough then to ask how my pullets were hatched and raised, but they obviously weren't mass produced. At my house, they didn't have acres of land, but they did get out in my garden on grass and shrubs for at least some time every day. I think it was a good life for them.
