Just to give an example, I (and I think most humans) feel negatively about deforestation or destruction of plant life because it is destroying or profaning something beautiful. It’s like burning art.
Same with the chickens. I’m not sure I consider factory farming immoral, and I definitely don’t consider killing animals for food immoral. I grew up raising chickens (laying hens, it was a family hobby and not a business)and don’t feel any moral or aesthetic issue with killing them. I also hunt and fish a lot, my freezers are full of wild game whose lives I personally ended.
Still, certain kinds of factory farming, like the raising of chicken-blobs, disturb me because they take something I find beautiful and make it ugly. Not sure what to make of the disturbed feeling tho, it’s not a moral condemnation or political position.
That’s the best way I can put it on the internet.
