It is recommended to cook chicken on the bone for seven to eight hours on low and three to four hours on high. Boneless chicken takes less time to cook. The average weight of a chicken is 3 1/2 to 4 lbs., and the cooking time is based on this weight.
Boneless Chicken Breast
Because chicken breast is boneless it requires less cooking time. Be sure to decrease the cooking time to avoid overcooking and drying out the meat. In addition to this, when cooking chicken in a crock-pot try adding liquid ingredients like soup to maintain moisture.
Note: Chicken should always be cooked to a specific temperature; 165 degrees Fahrenheit in the center for chicken breasts. Keeping track of the internal temperature of the chicken is your best bet for achieving juicy on the inside, crisp on the outside crock pot chicken.
