A lot of the time when chicken goes on sale, it is sold in the family size packages. Because of this, I like to cook the entire package of chicken instead of just dividing the chicken to put it in the freezer so that I can just grab it and put it in whatever we are having for dinner instead of thawing it and cooking it first. So, because I have a very close relationship with my crockpot, I grab it out, put the whole package of chicken in and add one cup of water. Then I put it on low for 4-6 hours and let it do its thing. If I don't have time to cook the chicken right away, I sometimes freeze the whole package then cook it (from frozen) in the crockpot the same way at a later time. Amazingly, it doesn't take any longer to cook it from frozen than it does from thawed and it tastes the same. I don't season my chicken while cooking this way because I prefer to do so when I am using it for whatever I am using it for. But, if you prefer, feel free to season with salt and pepper before placing in the crockpot. You don't get a lot of chicken stock with this method, but I still end up with a little stock (usually around 2 cups. The cup of water "grows" with the juices from the chicken) for the freezer. When I am in need of more stock, I will take the time out to cook my chicken in a stock pot on the stove instead, but truthfully I save enough here and there that I rarely need to do this.
