Preheat the oven to 375°F (190°C).
In a mixing bowl, combine the shredded chicken, cream cheese, cheddar cheese, garlic powder, onion powder, and parsley.
Season the mixture with salt and pepper to taste.
Unroll the crescent roll dough onto a clean surface and separate the triangles.
Place a spoonful of the chicken mixture on the wider end of each triangle.
Roll the dough from the wide end to the tip, tucking in the sides slightly as you go.
Arrange the rolled crescents on a baking sheet lined with parchment paper.
Bake in the preheated oven for 12-15 minutes, or until golden brown.
Remove from the oven and let cool for a few minutes before serving.
