Drain the canned chicken and place it in a medium mixing bowl.
Add the cream cheese (room temperature), chopped onion (or 1/2 teaspoon onion powder), garlic powder, kosher salt, and 1/2 cup of the chopped pecans to the bowl.
Mix thoroughly until well combined and smooth, using a spoon or spatula.
Place the mixture in the center of a large piece of plastic wrap and shape it into a ball by wrapping and pressing the plastic around it.
Unwrap the ball and press the remaining chopped pecans onto the top and sides to coat evenly.
Wrap the coated cheese ball in plastic wrap and refrigerate for at least 1 hour (can be stored up to 3 days) before serving.
Unwrap and serve the chicken cheese ball with crackers and fruit.
