I think if you keep chickens as pets, that's great. Most people around here keep chickens as livestock, or maybe a small backyard flock as semi-pets. I do agree that chickens are mostly considered dispensable, both as livestock and backyard flock pets. They don't share the same status as cats or dogs for most people.
I think that's great. Just be aware that many people don't consider their poultry as pets and probably will not be willing to spend $$$ on them. We have a couple veterinarians around here where I live, but none of them know anything about chickens. If we can't treat our sick chicken(s) on our own, they get culled and replaced.
