Add flour and salt and mix thoroughly. (Dough will be crumbly.)
Stir in 1 Tbsp. milk.
Chill dough until firm enough to roll into balls.
Meanwhile, melt candy melts and dip pretzel sticks to coat. Leave 1 cm. at the bottom of each stick. These will be the feathers.
Dip small pretzels in red candy melts for the turkeys' feet.
Roll dough into 8 balls.
