Place the chicken in a crockpot. Sprinkle the ranch seasoning over the chicken and place the stick of butter on top. Add the pepperoncini peppers and the pepperoncini juice.
Place the lid on the crockpot and cook on high for 4 hours, or on low for 8 hours.
Remove the lid, and shred the chicken in the juice with 2 forks. Serve as desired.
