it’s a machlokess between the many american poskim.
on one hand, chanukah is a time of hoda’ah and therefore we praise and thank hashem in the birchas hoda’ah of shmona esrei, with al hanisim. however bringing a turkey into the picture totally takes away our focus of our jewish way of thanking and celebrating chanuka, and shouldnt mix into our menu.
mitzad hasheini, we must thank hashem for everything, even for our country, and is a welcoming addition to our plates once we’re in the ‘thanking mode’.
the universal minhag is to compromise and to prepare and mold potato latkes in the shape of a turkey.
