Thanks for suggesting that, Nathan! For context:

I arrived at a cost-effectiveness of corporate campaigns for chicken welfare of 15.0 DALY/​$ (= 8.20*2.10*0.870), assuming:

• Campaigns affect 8.20 chicken-years per $ (= 41*1/​5), multiplying:

  • Saulius Šimčikas’ estimate of 41 chicken-years per $.

  • An adjustment factor of ¹⁄₅, since OP [Open Philanthropy] thinks “the marginal FAW [farmed animal welfare] funding opportunity is ~1/​5th as cost-effective as the average from Saulius’ analysis [which is linked just above]”.

• An improvement in chicken welfare per time of 2.10 times the intensity of the mean human experience, as I estimated for moving broilers from a conventional to a reformed scenario based on Rethink Priorities’ median welfare range for chickens of 0.332^[6].

• A ratio between humans’ healthy and total life expectancy at birth in 2016 of 87.0 % (= 63.1/​72.5).

In light of the above, corporate campaigns for chicken welfare are 1.51 k (= 15.0/​0.00994) times as cost-effective as TCF [GiveWell’s Top Charities Fund].
