Hi Omnizoid,

I have recently posted a cost-effectiveness analysis on corporate campaigns for chicken welfare. I used Saulius Šimčikas’ estimates from 2019, Open Philanthropy's adjustment from 2023, and some others I added in my own analysis. I conclude broiler welfare and cage-free campaigns are:

• 168 and 462 times as cost-effective as GiveWell’s top charities, i.e., way more.
• 0.261 % and 0.718 % as cost-effective as Shrimp Welfare Project’s Humane Slaughter Initiative, i.e., way less.
