Ynet has an interview with Empire Kosher's new president.
Although not mentioned in the article, Empire uses only free-roaming chickens while Rubashkin's are all cage-grown.
Also note that Empire's major effort to reclaim its base was to add KAJ supervision and move to the 'right.' But this move has nothing to do with kosher and everything to do with branding. As always, in today's Orthodox world, the external veneer is far more important than the actual status of any thing, any person or any idea.
Predictably, the shtreimel makes the man.
