Does a rabbi bless every chicken in kosher meat plant?

No, a rabbi does not bless every chicken in a kosher meat plant.

In kosher slaughter, a rabbi or a specially trained shochet (ritual slaughterer) performs the shechita, which involves a quick and precise cut to the animal's neck. The shechita is done according to strict Jewish ritual laws and is intended to ensure that the animal dies quickly and painlessly.

After the animal is slaughtered, it undergoes a process of inspection and preparation to ensure it meets the kosher dietary requirements. This process includes removing certain parts of the animal and checking for any defects or injuries that would render the meat non-kosher. However, it does not involve a rabbi blessing each individual chicken.
