Thanks for this. I think this stems from the same issue as your nitpick about AMF bringing about outcomes as good as saving lives of children under 5. The Founders Pledge Animal Welfare Report estimates that THL historically brought about outcomes as good as moving 10 hen-years from battery cages to aviaries per dollar, so we took this as our starting point and that’s why this is framed in terms of moving hens from battery cages to aviaries. We should have been clearer about this though, to avoid suggesting that the only outcomes of THL are shifts from battery cages to aviaries.
Note that (unless I missed something) your animal welfare report commits this same minor mistake of assuming that all hens used by companies that made cage-free commitments were in battery cages. While I think that’s true for the majority of hens, some of them were already in cage-free systems, and some were in enriched cages. But this is more than outweighed by some very conservative assumptions. E.g., that THL’s work only moved policies forward by 1 year or something like that. So it’s no big deal :)
What is way more important is all the indirect effects and other factors that I list in the “Ways this estimate could be misleading” section of my corporate campaigns CEA here. I think that they might be more important than direct effects. The same could also be true about AMF.
