Place all three chicken breast and chicken broth in your crockpot.
Cook on high for 1.5 hours.
Remove one cup of chicken broth, and shred chicken with a hand mixer.
Once the chicken is shredded, add cream cheese, ranch, and wing sauce.
Cook on low for 2 hours, stirring occasionally.
Mix well and spoon on to buns.
Top with shredded mozzarella cheese, and place the sandwich in the microwave for 15 seconds to melt cheese.
Serve and enjoy!
