I’ll stick with Kirkland Signature which is supplied by Wilcox. I don’t really think Costco ever raised their egg prices afaik.

Edit: it is a bit opaque but their main supply network allegedly includes Wilcox and Handsome Brook which are rated decently

Has Costco ever commented on its suppliers/sustainabillity or ethicality in this context?

[SlightlyLeftPad]

Sadly no, so it’s likely opaque intentionally, for reasons.

Costco always enforces strict opacity on it's vendors as a trade secret - it allows them to negotiate from a position of power with fairly large players as well as preventing competitors like Walmart from potentially undercutting Costco by forcing an exclusivity deal or price war.
