Too many people, likely boarding on most at least in the western world, are insulated from where food comes from. The emotional hang-ups associated with killing livestock for the table or eating products like eggs are just that, emotional. Good judgment is all to easily clouded by human emotion and that is the basis for many a poor decision with respect to animal care.
Being able to raise and havest farm animals for the table is becoming a lost skill, without people having some exposure to this it is going to be hard to develop a balanced prespective.
One thing to I see happening that is a slippery slope is people projecting human emotions on chickens or other farm animals, things like "my chicken is depressed" or "I hurt my chickens feelings"... Soon as this sort of stuff happens I'd say all objectivity is gone with respect to making good animal care or farming decisions. Chickens don't sense the world as we do, their brains are not wired the same and it is silly and egotistic to think that every other animal thinks, precives and senses the world the same way we do.
Don't get me wrong I like to see our amimals have a good healthy life. But they all have their purpose.
