The Rule To Remember For The Juiciest Slow-Cooked Chicken - Tasting Table
Briefly

Slow cookers excel at offering a hands-off cooking experience, providing moist and tender chicken through a low-and-slow cooking method that locks in flavors.
Ensuring that the chicken is fully submerged in liquid is crucial for even cooking and safety; fill the cooker halfway to three-quarters for best results.
To reduce excess liquid after cooking, briefly uncover the slow cooker and increase to high heat for 30 to 45 minutes to achieve a thicker sauce.
Avoid lifting the slow cooker's lid during cooking to maintain steam and heat; losing steam can cause cooking times to increase significantly.
