It's more like they were raised in farms with one common space for the birds, still extremely cramped with probably no grass or natural light but maybe slightly better than battery cages.
They'd like you to believe that the 130 farms they collect eggs from resemble the one they videoed - https://www.youtube.com/watch?v=a9MZdfAUlXs - but it's hard to evidence objectively.
Clarence Court's eggs are pretty expensive compared to other brands -- obviously that's nothing to do with conditions but
I can say all the ones I've bought so far have been really, consistently good quality.
I'll be very disappointed if I find they're battery-farming too.
It would be fantastic if all farms were like that! Industrial animal farming is the most profitable and scalable from a business perspective, but horrifying from a moral point of view.
