Constructing an ethics that demands that a chicken act as a moral agent is obviously nonsense; chickens can’t and won’t act that way. Similarly, constructing an ethics that demands humans value chickens as much as they value their own children is nonsense; humans can’t and won’t act that way. If you’re constructing an ethics for humans follow, you have to start by figuring out humans.
It’s not until after you’ve figured out how much humans should value the interests of chickens that you can determine how much to weigh the interests of chickens in how humans should act. And how much humans should weigh the value of chickens is by necessity determined by what humans are.
Well, if humans can’t and won’t act that way, too bad for them! We should not model ethics after the inclinations of a particular type of agent, but we should instead try and modify all agents according to ethics.
If we did model ethics after particular types of agent, here’s what would result: Suppose it turns out that type A agents are sadistic racists. So what they should do is put sadistic racism into practice. Type B agents, on the other hand, are compassionate anti-racists. So what they should do is diametrically opposed to what type A agents should do. And we can’t morally compare types A and B.
But type B is obviously objectively better, and objectively less of a jerk. (Whether type A agents can be rationally motivated (or modified so as) to become more B-like is a different question.)
Of course we can morally compare types A and B, just as we can morally compare an AI whose goal is to turn the world into paperclips and one whose goal is to make people happy.
However, rather than “objectively better”, we could be more clear by saying “more in line with our morals” or some such. It’s not as if our morals came from nowhere, after all.
