There can be amounts of things other than suffering, though. Caring about the “number of chickens that lead meaningful lives” doesn’t mean that one isn’t a utilitarian. (For the record, I agree with the OP that the notion of “leading meaningful lives” isn’t so important for animals, but I think it’s possible to disagree with this and still be advocating an EA intervention.)

There can, but in practice the amount of suffering is usually the stated reason to care.
Ah sorry, I seem to have misread your comment. Makes sense now, thanks!
