I kinda partially agree with Max here. While I certainly agree that there should be reasonable methods taken to reduce unneeded cruelty to our food animals, some is going to be innate in the idea of keeping animals for food. My grandparents owned a dairy farm with some chickens on the side. None of those animals were ever intended for the slaughterhouse and to my at the time young mind felt they were well treated, yet there are plenty of people out there who would feel myself and my grandparents were monsters, simply for owning livestock.
I like eating meat. I don't like that in order to keep many kinds of meat cheap they have to be kept in conditions many would consider inhumane. But unfortunately until we get food to the point where everyone can have easy, basically free access to as much as they need of a fair variety, including meat, that is the reality.
If we can develop cultured meat that does not have significant issues that will reduce the need for walls of chicken cages stacked on top of another, that's great. If someone can market an insect meat successfully that can be mass farmed instead that would be great. If someone chooses to be a vegetarian, or vegan, and reduce the overall demand for meat to make these mass meat farming methods less of a requirement thats great as well. But it should be a person's right to eat meat if they wish, animals are not people, and until alternatives are developed we have to do what we have to do.
