What farm do Costco eggs come from?

I'm curious, could you please enlighten me on the origins of the eggs sold at Costco? Specifically, which farm or farms are they sourced from? It's important for many consumers to know the provenance of their food, and I'm sure Costco's customers are no exception when it comes to their eggs. So, if you have any information on the matter, I'd be grateful if you could share it with me.
