"Some people might get easily confused by this, but breeding an individual for multiple generations with a goal or objective in mind, and causing some degree of change to their genes over that period doesn't make it more ethical to continue ignoring the fact that they are individuals with their own goals and desires and using them simply for your own benefit."

Well that's just according to you unless its applied to people. Like... the chickens don't actually know whats going on. And those chickens aren't going to continue to exist unless we use them for meat. Like how is it more ethical to choose to let an entire species die out instead of just eating them and giving them an actual purpose along with a life? That's like saying it would of been better if all the Jews had died in WWII instead of surviving and going on to have families and crap. Like you don't get to choose who's better of dead you're not god. Plus they're ANIMALS. They pretty much don't matter that much. That's why people can accidentally run over them or swat them on purpose with a swatter or hunt them and never get in trouble. Like no one actually cares about animals unless they're pets not even vegan people. They think they do but they really don't and being vegan is a huge waste of time fighting a losing battle that'll never win. AND you miss out on cool food so it's double crap.

AND btw, those chickens are still literally useless with no point except to waste resources. They're a waste of time, food and money that could have been spent on people or animals that help people in some way.
