I've done whole chicken in the crockpot and it's never gotten brown like a roast chicken. False advertising

Did you taste it before you threw it away? The secret I have found is to rest the whole chicken on a bed of potatoes onions and carrots. That way the juices fall down and the chicken doesn't stew in its own juices all day long. Then you can eat the carrots and potatoes too! They are not as greasy as you'd think they would turn out. It's not the best chicken in the world but it does the trick when we are busy. I serve it with sauces to dip, like BBQ sauce. Then after dinner I clean out the crockpot and throw the carcas back in with fresh onions, carrots, celery, bay leaves and pepper corns and put it on low overnight and have a delicious chicken stock in the morning!
