In the sink, unwrap the chicken and turn it upside down so the guts fall out into the wrapper and move the wrapper to the side (See, you don't even have to touch them!). Rinse the chicken inside and out well. Try to drain all of the water out of the chicken.
Spray your crock-pot with cooking spray and set it in, breast side up. Spray the chicken with cooking spray. Lightly season with salt, pepper, garlic powder, and season salt. Put the lid on and let it cook on low for 8-10 hours. My crock-pot cooks very quickly, though, so I do it about 6-8 hours. If you leave it too long, the bones start to decinegrate - yuck! Don't add any water or broth. The chicken will make its own juice and your house will smell amazing!
Serve with whatever sides you like. :-)
