Complete ALL 5 Captain Kidd missions that are unlocked by collecting trinkets to get the Shard Of Eden ring. The Shard Of Eden ring will decrease your chances of being hit by bullets. When the ring deflects a bullet a yellow animation will appear.
At any point after Sequence 6 go to the Davenport Homestead and walk around the right side of the manor and hide around the corner at the back. Then in Stealth mode lean against the wall and whistle. Approach the turkey when it appears nearby and press Up, Up, Down, Down, Left, Right, Left, Right, O, X to feed it. The turkey will now don an assassin's hood, and follow you around.
