Thanks for the pointers on where to start looking. This is helpful.

The modern “factory farming” is not something I care to defend for any intent or purpose. It may as well disappear tomorrow, as far as I am concerned.

However, I still see no argument against deeply caring domestication of a small number/herd of animals, providing them food, shelter and care in exchange for milk or unfertilized eggs. Can’t seem to find a convincing argument against that in my current ethics framework.
