I probably already know the answer to this question, but thought i'd find out what other chowhounds think. My sister called and asked whether I thought a week old Costco roast chicken was too old to make stock with. This is one of those completely cooked roasted chickens they sell (absolutely delicious and cheap for $4.99, btw). They never got around to picking off all the chicken so she was going to throw the chicken with meat still attached along with some vegetables and herbs, into the slow cooker to make chicken stock. Do you think this is still safe to eat/make stock with?
I usually throw my chicken bones into a zip lock bag and keep them in the freezer until I have enough bones to make stock. I'm a little unsure about whether this chicken is past it's prime for making stock. What about the chicken that's left on the carcass? If you cooked the whole chicken overnight in the slow cooker, would the picked off meat be safe to eat if you were to make chicken vegetable soup?
