> I imagine farmers who treat animals well

This is a cherry picked argument, at least in the US, where "factory farms raise 99.9 percent of chickens for meat, 97 percent of laying hens, 99 percent of turkeys, 95 percent of pigs, and 78 percent of cattle" [1].

Besides, even in this ideal farm where the farmer treats the animals perfectly and lets them live long, fulfilling lives, they're still killing the animal at the end of the day. Hard to see how that is "treating [it] well".
