This post estimates that animal welfare interventions may be ~10x more effective, implying $450 /​ human life-equivalent, though this is an especially rough number.
I have estimated corporate campaigns for chicken welfare are 10,000 times as effective as GiveWell’s Maximum Impact Fund, for a moral weight of chickens relative to humans of 2 (most people think this is too high, but I think it is reasonable; see discussion here).
