The vegetables should be perfectly fine to eat. They'll probably be mushy after 8 hours of cooking, but that's the only issue I can think of with them.

Yeah, they were a bit mushy, but not too bad. I just made a little soup with them and some of the stock and it was good. :)

If you'd roasted the chicken, I'd tell you to keep the carcass to make stock out of. But 8 hours in a crock pot should have gelatinized all the cartilage and bone matter it could and cooked all the flavor out of it. Tossing the bones is fine at this point.

That's what I thought, but I wanted to make sure just in case. Thanks for the info! :)
