The Massachusetts Division of Fisheries and Wildlife is out with some "tips for aggressive turkeys" (more specifically, how we can deal with them, not tips for turkeys looking to get ragier). Among them:
Don't let turkeys intimidate you. Residents can threaten a bold or aggressive turkey by making loud noises, swatting it with a broom, or spraying water from a hose. A leashed dog is also an effective deterrent.
Also, ditch your bird feeders and cover your windows and anything shiny: Turkeys love bird feeders; but hate the "turkeys" they think are menacing them when they see their reflections and will go after them because it turns out pecking orders are a thing when it comes to turkeys.
And never feed them. Not after midnight, not before midnight, never.
