Spoon salsa on top of chicken and spread to cover the chicken.
Cook on low for 3-4 hours, or on high for 2 hours, until chicken is cooked through. I cook on low.
Remove chicken to a plate to cool slightly, along with the salsa that is on top of the chicken.
Shred with two forks or your fingers and place in a bowl.
Stir in some of the liquid from the slow cooker, starting with a few tbsps and adding more as desired.
