"More than 50 percent of Empire Kosher's Thanksgiving turkey volume is from non-kosher consumers," company spokesman Elie Rosenfeld told CNBC.

For those who like to brine turkeys to lock in moisture and add flavor, kosher turkeys already do the job for you. Plus, Rosenfeld said some consumers like the idea that every turkey must be killed by hand by a rabbi in a method meant to reduce an animal's suffering.
Empire has 60 trained rabbis on staff at its plant in Mifflintown, Pa., one-tenth of the company's workforce.
Americans have been switching to poultry this fall as beef prices have boomed, a fact borne out by Tyson Foods' earnings this week. Tyson poultry profits rose even as feed costs shot up due to the drought.

Rosenfeld said kosher turkeys already cost more due to their special processing. Empire Kosher said it takes over three hours to process a kosher bird, compared to only one hour at a non-kosher plant.
Feed accounts for nearly a third of all costs. "All our birds are all-vegetarian fed." Yet Empire has only passed some of those costs along to stay competitive, and volume is up 12 percent from a year ago.

Finally, here's a shocker. Going kosher may actually be the true Thanksgiving tradition!
According to Aish.com, "the world's largest Jewish content website," the REAL first Thanksgiving wasn't between the Pilgrims and Native Americans in 1621, but three years earlier in the Catskills, "according to the Academy of Obscure Jewish History".
In a hilarious case of revisionist history, the academy's "research" discovered the hidden history of how the two ... tribes ... came together for a feast to give thanks. "The Ongepatsht Indians would be invited and the Jews briefly considered having the affair catered before finally deciding to do it all themselves to save money."
