Don't mean to nitpick but Braum's isn't a co-op/consortium. It's a single family's massively-integrated retail operation. They own and operate basically all of their farms and ranches along with the manufacturing plants for their containers and even their delivery fleet. Braum is the last name of the guy who founded it.

(Oh, and it's not Texan. Braum's is an Okie brand; they don't open up stores more than about 300 miles from their central farms in Oklahoma.)
