If you have the ability, have your own hens. It’s a really rewarding experience and then you can know for sure that the hens are happy and treated well.
Unfortunately, I’m moderately uncertain about this. I think chickens have been put under pretty tremendous selection pressure and their internal experiences might be quite bad, even if their external situations seem fine to us. I’m less worried about this if you pick a heritage breed (which will almost definitely have worse egg production), which you might want to do anyway for decorative reasons.
Similarly, consider ducks (duck eggs are a bit harder to come by than chicken eggs, but Berkeley Bowl stocks them and many duck farms deliver eggs—they’re generally eaten by people with allergies to chicken eggs) or ostriches (by similar logic to cows—but given that they lay giant eggs instead of lots of eggs, it’s a much less convenient form factor).
