Crock pot question?

I cooked a chicken (about 5 lbs) in my crock pot on low for about 7 hours and it simmered in about a half a cup of chicken broth to keep it tender. Do I still need to cook it in the oven? I don't have a thermometer but it is white in color and appears to be done. I am in favor of using the crock pot for the convenience of allowing it to slow cook while I do as I please while the chicken usually turns out quite tender. What is your opinion and please share any ideas regarding crock pots as I am always open to new ideas. Thank you in advance!
