You can't roast a chicken in a slow cooker, but you can just put a whole chicken in the slow cooker with salt, pepper, herbs if you like, and cook for about 4 hours.
Very nice.
yes lovely very tender done it a lot. If you pour off juices when chicken is ready and leave a few minutes it dries up the skin making more like oven done. mmmmmmm
Yes I have tried it and it was nice but not a lot better than when cooked in the oven. I cooked it in chicken stock, sage, thyme, onion and lemon, and that made wonderful gravy. Alternatively the lamb, beef and pork joints i do in the slow cooker are much nicer than oven cooked IMO
