For me that is one of the perks! The only chicken I eat are the ones I raise myself, and I only try to crockpot the older ones that might be a little tough cooked by another method. The "falling-off-the-bones" tender is what I am looking for.
Does your regular oven have a cook timer? I use it sometimes to cook a meal, although 11 hours is a LONG time to have it waiting. If I am going to be leaving the house early afternoon and want dinner ready by 6-7, I will prepare the meal in the morning, then put it in the oven at 1pm, set the time to turn the oven on at 4 and cook for 2 hours and it will turn off and keep it warm until we are home.
