The sheriff is sitting at the table with the killer turkey wearing a turkey costume for the annual ball. The turkey kills the sheriff and when it shows him hiding the sheriff's body, the sheriff isn't wearing the costume.
When Kristen calls her Dad in the jeep, he asks her to come with him to a ball that night. Later when she calls him from the woods, she tells him that their car broke down, they're staying in the woods, and she'll be home in time to go to the ball with him tomorrow night.
After the demonic turkey steals the car early in the film, it is clear in the next shot that the driver behind the wheel is human and wearing a seat belt as opposed to the demonic turkey driver one should expect.
The film takes place in New England at Thanksgiving time. The characters are walking around in shorts and short sleeved shirts. If the filmmakers had spent any time in New England in November, they would know that it's way too cold to walk around in shorts and short-sleeved shirts.
