Mix softened cream cheese with the ranch powder, cheddar cheese, 1 tablespoon milk, bacon, and chicken until well combined. Add more milk if desired.
Spread about ¼ cup of chicken mixture evenly on each tortilla.
Roll the tortilla up gently, yet tightly to make sure it holds together and keeps its shape.
Refrigerate for about 30 minutes to firm up the softened cheese.
Cut off ends of the tortilla roll and cut into 1-inch slices.
