Can I cook chicken in the crock pot?

Yes, you can. I do it all the time. I like to do it very simply. Put the chicken in along with two bottles of beer for the liquid and let it go on high for almost all day (until it starts to fall off the bone). The beer gives it a nice flavor and then I use the chicken to make sandwiches with BBQ sauce (like pulled chicken sandwiches), add the chicken to pasta, put the chicken on nachos or in tacos, etc.
