i don't consider chickens as pets. my conure is a pet. some of my dogs are pets. some dogs hunt for me. they are hunting dogs. chickens are livestock and they are here to feed me and put money in my wallet. would i be sad if some of my older hens died or got killed? of course. they are still livestock and part of the farm(food).
Our goals may change as we add different breeds, but the ones we have right now (except for the cuckoo marans cockerel) are a light breed and none were purchased for food, just eggs and pest control. I had no idea how much fun they would be!
I know that many people do get chickens for food, we may too, at some point. Not sure about that yet, but I do believe that chickens raised in the BYC fashion, on farms and such, have a much better life than those raised in a commercial setting whether they end up on the table or not.
