E.g. Healthier Hens doesn’t seem like it has been able to demonstrate that it is cost-effective to donors at a small scale. Why would scaling it up 1000x go better?
FWIW, I thought some interventions they were exploring looked potentially pretty cost-effective, near the bar for marginal animal welfare work, and with a ratio of 7 years of disabling chicken pain prevented per year of waking human life saved by GiveWell recommendations. See here.
Ah, FWIW, the ideas that looked cost-effective were not related to keel bone fractures or based on feed fortification. Their feed trial ended up going badly for the hens.

Healthier Hens has since shut down, though, and CE/AIM is looking to start a keel bone fracture charity with a different and much higher leverage strategy: certifier outreach. This probably can’t absorb nearly as much funding, though.
Nice—that’s good to know—I was under the impression that it was a good idea, but didn’t get much traction.
