Today's patch sneakly added a new world boss, [creature_megaturkey]. Killing it gives you [item_massiveturkeylegt5], which is an ingredient needed to craft [recipe_foodconluct5].
The food gives you a constitution and luck boost based on your level, with level 60 giving you 33 constitution and 5% luck. You can check the bonus for any level you want by going going to the [item_foodconluct5] page.
It's currently unknown how the big guy made its way into the game since there was no mention in today's patch notes. Tosch, a community manager at New World, replied to a post on the forums with a message saying "THE REVENGE OF THE TURKEYS!" so, maybe this is actually the turkeys taking their revenge after Thanksgiving! Not quite sure that was a good idea from the turkeys though...
Players are reporting that the respawn time for [creature_megaturkey] is around 3 hours. Here are some of the locations where you can find it:
