That’s some excellent steelmanning. I would also add that creating animals for food with lives barely worth living is better than not creating them at all, from a utilitarian (if repugnant) point of view. And it’s not clear whether a farm chicken’s life is below that threshold.
I think it’s fairly clear that a farm chicken’s life is well below that threshold. If I had the choice between losing consciousness for an hour or spending an hour as a chicken on a factory farm, I would definitely choose the former.
Ninja Edit: I think a lot of people have poor intuitions when comparing life to non-life because our brains are wired to strongly shy away from non-life. That’s why the example I gave above used temporary loss of consciousness rather than death. Even if you don’t buy the above example, I think it’s possible to see that factory-farmed life is worse than death. This article discussed how doctors—the people most familiar with medical treatment—frequently choose to die sooner rather than attempt to prolong their lives when they know they will suffer greatly in their last days. It seems that life on a factory farm would entail much more suffering than death by a common illness.
I don’t see why a chicken would choose any differently. We have no reason to believe that chicken-suffering is categorically different from human-suffering.
If we were to put a bunch of chickens into a room, and on one side of the room was a wolf, and the other side had factory farming cages that protected the chickens from the wolf, I would expect the chickens to run into the cages.
It’s true that chickens can comprehend a wolf much better than they can comprehend factory farming, but I’m not quite sure how that affects this thought experiment.
Even if this is correct, in terms of value spreading it seems to be a very problematic message to convey. Most people are deontologists and would never even consider accepting this argument for human infants, so if we implicitly or explicitly accept it for animals, then this is just going to reinforce the prejudice that some forms of suffering are less important simply because they are not experienced by humans/our species. And such a defect in our value system may potentially have much more drastic consequences than the opportunity costs of not getting some extra live-years that are slightly worth living.
Then there is also an objection from moral uncertainty: If the animals in farms and especially factory farms (where most animals raised for food-purposes are held) are above “worth living”, then barely so! It’s not like much is at stake (the situation would be different if we’d wirehead them to experience constant orgasm). Conversely, if you’re wrong about classical utilitarianism being your terminal value, then all the suffering inflicted on them would be highly significant.
I find the argument quite unconvincing; Hanson seems to be making the mistake of conflating “life worth living” with “not committing suicide” that is well addressed in MTGandP’s reply (and grandchildren).
This is a good point, and was raised below. Note that the argument doesn’t seem to be factually true, independent of moral considerations. (You don’t actually create more lives by eating meat.)

I probably would too, but I am not a chicken. I think you are over-anthropomorphizing them.

And I expect that a human would do the same thing.
I made a hash of that comment; I’m sorry.
This is testable; give the chickens a lever to peck that knocks them out for an hour.

Robin Hanson has advocated this point of view.
