Agrees with
@Shadrach ....defining the meaning of 'pet' and 'livestock' is going to be seriously subjective... so, different for everyone. I won't even attempt to define that, even for myself....except to say I'd take a sick dog to the vet, but not a chicken. I'd never eat my dog, or any dog, unless maybe I was
truly starving(I don't think anyone really knows what they'd do in that case). But my dogs cats parakeets cockatiels finches turtles frogs fish and even insect 'pets' that I have had are also not my 'children' and I am not their 'mother'. I've given birth twice, buried one of them....non human animals are
not children
or family members. Anthropomorphism is an unhealthy thing, IMO...animals can be an important and satisfying part of our lives, but they are not humans.
I keep chickens for
food, eggs
and meat, where I provide and control the environment they grow in, because I believe animals should live in a decent environment even(maybe especially) if I am going to kill and eat them. It's not as much about 'purity' of food source as it is about taking personal and pragmatic responsibility for the food source. I like to eat chicken and should be able to kill one if I want to eat chicken...not that I personally slaughter every animal I eat, tho much of the meat I do eat is raised 'responsibly' by people I know. But if I am going to keep chickens for eggs and hatch out more replacement layers, I have to face the fact that half those chicks will be male and I can't keep them all, the older hens are not going to be productive enough to house and feed them, so I kill and eat them. It's a realistic and also economic decision, I can't afford to feed nonproductive birds, egg sales pay for their feed, and also a crowded environment is not a decent one.
Although my chickens are food animals it doesn't mean (believe it or not) that I am coldly unfeeling about killing a bird or watching an animal suffer needlessly when ill or injured(they are euthanized), or that I don't feel some affection for(some of) the chickens in my care. I greatly care and astutely observe their antics and behaviors, because it fascinates(entertains?) me and I need to do that to make sure they have what they need to be healthy, comfortable.... and, yes, productive.
